The tungsten carbide inserts underwent cryogenic treatment in a specially designed cryogenic chamber (KRYO 550-16), capable of cooling samples down to deep cryogenic temperatures (-196 °C). The chamber’s temperature was gradually reduced from room temperature (RT) to the cryogenic temperature (CT, approximately -196 °C) at a rate of 2 °C/min as shown in Figure 1B. After being maintained at this temperature (-196 °C) for 24 and 36 h, the temperature was gradually raised back to room temperature (Devi and Mahalingam, 2023). Additionally, the current experiment was conducted to thoroughly examine the performance of cryo-treated cutting tools on Custom 450 stainless steel. The objective was to determine the optimal parameters at various spindle speeds (1,500 rpm, 2,300 rpm, 3,100 rpm), feed rates (0.1, 0.15, 0.2 mm/min), and a constant depth of cut (0.5 mm).

In this formula, Rij represents the i th run j th response value, Rbj is the best j th response value, and Edi is the Euclidean distance. The process involves calculating the Euclidean distance for each run and then computing the IGD as the sum of each Euclidean distance squared, divided by the number of runs (27 in this case).

Figure 3 shows that cryo-treated inserts exhibit better surface roughness than untreated inserts. Surface roughness decreases with increased spindle speed and increases with feed rate from 0.1 to 0.15 mm/min and further with 0.2 mm/min.

Cryogenic treatment of metal leads to the transformation of the austenite phase into the martensite phase, characterized by a well-structured grain structure and a body-centred tetragonal crystal structure (Sert and Celik, 2019). The superior, tougher structure of martensite provides high wear resistance. Cryo-treatment of cutting tools has been identified as an effective method for reducing cutting force, extending tool life, and improving wear resistance (Reddy et al., 2009; Ozbek et al., 2016). (Korade et al., 2017) observed that combining various types of cryogenic treatment with increasing tempering temperatures and levels led to decreased hardness and increased wear volume. Literature reviews indicate that cryogenically treated coated carbide inserts have enhanced machining capabilities and tool wear resistance (Kumar and Singh, 2015; Singla et al., 2018; Panchagnula et al., 2023a; Panchagnula et al., 2023b). High spindle speed operations benefit from increased tool life with cryo-treated tungsten carbide inserts. Tool life and surface finishing are significant factors in the machining process. Coatings and cryogenic treatment have been shown to improve surface polishing and increase wear resistance (Gill et al., 2012; Sahoo et al., 2020). (Jadhav et al., 2020) performed turning operations on P20 tool steel using cryo-treated cutting inserts, with experiments conducted using Taguchi’s L27 orthogonal array and results analysed using MATLAB surface plots and ANNs. Mukkoti et al. (Mukkoti et al., 2018) conducted end milling on P20 steel using cryo-treated tungsten carbide cutting inserts, with a focus on optimizing parameters affecting cutting forces and power consumption, using regression analysis to relate process factors to these outcomes.

Spurred by often unpredictable tool life and lengthy production times, TNG turned to ceramic inserts from Greenleaf. In the ring groove application, the company decided to use the Ring Max API ring groove cutter with WG-300 whisker-reinforced ceramic inserts. Designed specifically for the oil and gas industry, Greenleaf’s Ring Max line of ring groove tooling is engineered to reduce the machining time of API ring grooves, while the basic concept of WG-300 involves reinforcing a hard ceramic matrix with extremely strong, stiff, silicon-carbide crystals, or “whiskers.” The whiskers are dispersed into a matrix of fine-grained aluminum oxide, where they act much like glass filaments do in fiberglass, for example, by adding tensile strength and improving the fracture toughness of the brittle matrix.

Now, Mr. Hylton says the problem is the base material. “Before, I couldn’t wait to get there,” he says. “Now, when I hit the stainless, the chips come off in long strings. The inserts get a little beat up on the sides from the chips because face grooving is a nasty operation.”

CNC milling processes are widely used than the conventional machining in the manufacturing sector due to the accuracy. They are frequently employed to create complex shapes like pockets and slots. In industrial settings, hard materials are often milled using tungsten carbide end mill cutting tools, which are characterized by their higher hardness and wear resistance. This high hardness enables the processing of materials with high strength-to-weight ratios. During machining, cutting tools are subjected to high heat and variable loads. The cutting tools used for machining should not deform or wear excessively due to these conditions. Excessive softening of the cutting tool material, caused by high heat production during machining, leads to increased tool wear and cutting forces. This is problematic as tool failure is a common constraint, driving up component costs due to the need for tool replacement. Numerous efforts have been made in the past to enhance tool life and reduce surface roughness. However, optimizing cutting forces and cutting temperature with cryogenically treated tools in end milling of Custom450 stainless steel has not received significant attention in the literature to date.

Before switching to ceramics, TNG used carbide inserts to produce two API ring grooves on 31/8-inch-diameter valve bodies with a 1963 manual-engine lathe, a process that took between 10 and 15 minutes each to complete. The real challenge, though, was in reconditioning these valve bodies, because it often required cutting through difficult-to-machine materials such as Inconel. For instance, after opening the grooves in the cast steel base material 3/16-inch larger than the API specifications, the valve went to the welding department for Inconel cladding. From there, the process involved opening a straight face groove with a face grooving tool followed by an API ring groove tool. This was only possible by moving into the cut 0.100-inch axially, then moving in a positive and negative radial direction to the groove’s full width. After that, the machinist would move the tool in another 0.050 inch and blend from side to side to match the width of the previous radial cut. These tiny increments were repeated until the full depth of cut was reached. An experienced, efficient machinist like TNG’s lead machinist, Cimaron Hylton, could produce one groove in about 45 minutes, though many days it took closer to an hour.

The graphical representations of the association between response and cutting variables occur under specific cutting settings that were indicated in the experimental design table. Therefore, it is essential to comprehend how cutting conditions affect cutting variables in order to better clarify these interactions. Figure 6 displayed the combined effect of feed rate and cutting speed on CF fluctuations on three-dimensional graphs. The cutting force reduced as the feed rate and cutting speed increased. The cutting force reduced as the SS increased in the surface plot of CT and SS. Pareto chart (Figure 7) indicates the least significant impact of feed rate repetition on force in the X-direction. The primary effect plot shows reduced cutting force with increased spindle speed. The statistical analysis confirms the significant impact of milling parameters on CF during titanium alloy milling. The response surface plots demonstrate these effects, highlighting improved thermal conductivity due to cryogenic treatment, influencing the heat transfer from the tool’s tip and affecting cutting forces.

While the ceramic inserts could potentially be used for more than one groove, he says that he changes them after each groove to be on the safe side. But even at one groove per insert, he says he’s impressed with the predictability and longevity of the ceramic inserts. In fact, he’s quit trying to push tool life in the face grooving operation because the ceramic inserts are comparable in price to the carbide inserts when time savings are factored in.

The design factors that most affect the three quality attributes—manufacturing cost, tool life, and workpiece quality—are found using ANOVA. A high F-value indicates a high efficiency level for the parameter. Another important factor is the p-value, which allows statistical analysis to be completed within a 95% confidence interval. Consequently, the parameter affects the response if the computed value is less than 5%. According to Table 3. Cutting force, surface roughness, and temperature all had p values less than 0.05, indicating significant effects from each parameter on the output responses. Similarly, input parameters have a considerable impact on the output responses (square of FR, CT excluded), but no significant influence is seen on cutting force from square of FR, CT and no significant impact is seen on surface roughness from any of the interactions.

• Comparisons of CF, TT, and SR across various algorithms showed that ALO achieved the most optimal parameter settings.

According to Table 6, the IGD value for ALO is lower than for the other algorithms, indicating superior performance. The convergence graphs for Cutting Force (CF), Surface Roughness (SR), and Temperature (TT) in Figure 12 further demonstrate the effectiveness of the ALO algorithm compared to GHO, GWO, and HSA. Therefore, it is concluded that ALO outperforms GHO, GWO, and HSA.

The IGD metric is utilized to compare the effectiveness of Grasshopper Optimization (GHO), Grey Wolf Optimization (GWO), Harmony Search Algorithm (HSA), and Ant Lion Optimization (ALO) Algorithms. This measure indicates the computational complexity of the algorithms, as detailed in Khalilpourazari et al. (Khalilpourazari et al., 2020). The IGD is calculated using the Euclidean distance formula:

Although WG-300 is designed for excellent shock and wear resistance at high surface speeds for nickel- and cobalt-based superalloys, the grade is a good match for TNG’s application, which runs the materials at a relatively modest horsepower rating (20 hp) on its Hwacheon Vesta 1050B CNC mill.

Effect of process parameters on temperature is shown in Figure 11. Cutting temperature not decreases much. The Pareto diagram (Figure 12) suggests a uniform impact of feed rate and spindle speed on temperature. Residual analysis confirms a consistent pattern across milling operations without specific residue patterns, indicating the reliability of the experimental setup. The results validate the model’s suitability for analyzing cryo-treated cutting tool residues across various milling performance variables. The residual plots demonstrate the significant impact of input parameters on TT during machining.

Ant line Optimization (ALO) (Mirjalili, 2015), is another popular metaheuristic which models the hunting behavior of ant lions using traps. The algorithm represents an ant’s walk as stochastic. The ALO algorithm is shown in Algorithm 4.

The ceramic inserts really show their colors during the reconditioning applications, Mr. Hylton says. After the Inconel cladding is applied, he mills down the weld that’s bulging above the flange and follows up with the Ring Max tool, cutting the ring groove in just 28 seconds. Because ring groove machining is a continuous cut, through-spindle coolant is used. The coolant is used not to cool the insert, but to cause the chips to become more brittle and break into smaller pieces, sometimes becoming almost powder-like.

According to Mr. Hylton, taking such small depths of cut was necessary to reduce vibration and chatter, yet it didn’t fully eliminate it. Several times during the grooving process, machinists had to check the pitch diameter to ensure accuracy. They also had to hand-polish the angled groove walls.

Grey Wolf Optimization (GWO) excels in unfamiliar, challenging search areas and demonstrates strong convergence and local optima avoidance (Mirjalili et al., 2014). It simulates the Grey wolf pack’s predation process, which involves encircling, hunting, and attacking. GWO reflects the strict social hierarchy of grey wolves with alphas leading the pack, followed by betas, deltas, and omegas. In GWO, agents a,b, and d determine the best hunting strategy, while other wolves adjust their positions around the prey. The GWO algorithm is shown in Algorithm 2.

The current research examines the effectiveness of cryogenically treated (CT) tungsten carbide cutting inserts on Custom450 stainless steel using multi-objective soft computing approaches. The Taguchi-based L27 orthogonal array was employed in the experiments. During milling operations, cutting force, surface roughness, and cutting temperature were measured at different spindle speeds (rpm), feed rates (mm/min), and constant depths of cut (mm). The surface roughness and chip morphology of the Custom 450 stainless steel machined by cryo-treated (CT) and untreated (UT) cutting tool inserts were compared across various responses to cutting temperature and force. This paper also carried out multi-objective optimization, employing algorithm techniques such as Grasshopper Optimization Algorithm (GHO), Grey Wolf Optimization(GWO), Harmony Search Algorithm(HAS), and Ant line Optimization (ALO). The Multi-objective Taguchi approach and TOPSIS were first used to optimize the machining process parameters (spindle speed, feed rate, and cryogenic treatment) with different performance characteristics. Second, to relate the machining process parameters with the performance characteristics (cutting force, cutting temperature, and surface roughness), a mathematical model was developed using response surface analysis. The created mathematical response model was validated using ANOVA. The results showed that in IGD values of GHO, GWO, HSA and ALO module had 2.5765, 2.4706, 2.3647 and 2.5882 respectively, ALO has the best performance indicator. A Friedman’s test was also conducted, revealing higher resolution with the ALO method than with the HSA, GWO, and GHO methods. The results of the scanning test show that the ALO approach is workable.

The effectiveness of the system is evaluated using Design of Experiments (DOE), which considers several factors (Shanmugasundar et al., 2019a). DOE is an essential data collection and analysis methodology used across various experimental scenarios. It involves a planned experiment analyzing three aspects: factors, levels of these factors, and responses. The primary goal of DOE is to compare multiple solutions and identify the necessary factors to yield the best output response. It facilitates the examination of the impact of various input factors on a desired response. DOE is capable of identifying significant interactions that might be overlooked when examining a component at a time or dealing with multiple inputs simultaneously.

The foundation of the experiment design is the Taguchi-based orthogonal array, which includes three parameters and corresponding levels. This array can be used to develop optimal parameters, minimize treatments, reduce material costs, and determine the contributing factor of each process parameter in machining. The L27 orthogonal array consists of 13 columns, which can be assigned to test factors and their interactions. For a 3-factor 3-level configuration, the total number of tests required is given by 33=27. Therefore, a total of 27 experiments are to be conducted in the L27 OA. Table 1 shows the experimental design.

Custom 450 is a martensitic stainless-steel grade that has good resistance to corrosion up to about 650 °C and may be heat-treated to significantly enhance its mechanical properties. There are few articles regarding Custom 450 stainless steel in the literature, despite the fact that there are various studies on the machinability of stainless steels. Furthermore, publications do not contain information on end milling on Custom 450 stainless steel. The extensive use of Custom 450 stainless steel makes this experiment essential. Despite the established use of cryo-treated cutting tools in drilling, turning, and milling operations, the full potential of milling processes on Custom450 stainless steel has not been completely explored. While cryo-treated cutting tools are well-recognized in various machining operations, the specific application of end milling on Custom 450 stainless steel remains under-investigated. Furthermore, in-depth studies focusing on the end milling of Custom 450 stainless steel are still lacking. Consequently, the objective of this study is to investigate how process parameters influence the performance of a cryo-treated cutting tool during the milling of Custom 450 stainless steel. This investigation employs soft computing techniques, including the GHO, GWO, HSA, and ALO algorithms. Additionally, the study evaluates the effectiveness of these algorithms using TOPSIS multi-criteria decision analysis methods.

• Scanning Electron Microscope (SEM) examination of surfaces milled with UT inserts at high speeds and feed rates revealed significant grooves and ridges.

Stainless steels are widely used in springs, nuts, bolts, screws, and other fasteners, as well as in the health, maritime, defence, and nuclear power plants industries. This is because of their exceptional strength and robust resistance to oxidation and corrosion. Their superior mechanical characteristics, low heat conduction coefficient, and remarkable resistance to corrosion are the reasons behind this. Nevertheless, stainless steel alloys are usually used because of their many beneficial properties, such as their high flexibility, high tensile strength, high fracture toughness, and high work hardening rate. Aviation fittings, aerospace parts such as bushings, shafts, valves, and certain screws, fuel tanks, exhaust components, high-temperature engine parts, structural elements and cabin components, landing gears, and other items are among the many applications for custom 450 stainless steel. In the past work, using a cryo-treated cutting tool, custom 450 stainless steel is cut in different ways depending on temperature, and cutting force. Additionally, it aims to examine the workpiece’s surface morphology, chip anatomy, surface abrasion, and tool morphology. Now the work is extended, the objective of this study is to investigate how process parameters influence the performance of a cryo-treated cutting tool during the milling of Custom 450 stainless steel. This investigation employs soft computing techniques, including the GHO, GWO, HSA, and ALO algorithms. Additionally, the study evaluates the effectiveness of these algorithms using TOPSIS multi-criteria decision analysis methods.

In mathematics, the Multiple Linear Regression Model (MLRM) can be used to compute the response value (the output) in relation to multiple parameters (the inputs). Using experimental data and MATLAB’s “regress” function, this study establishes three variations of the MLRM equations: interaction Equations 8, (9), and (10) respectively.

• Utilizing cryo-treated (CT) inserts resulted in a 13% reduction in surface roughness compared to untreated (UT) inserts, particularly at high cutting parameters.

With the carbide inserts, Mr. Hylton says he had to peck at 0.005-inch depth increments to keep any edge at all. In addition, the retract amount that was programmed into the peck cycle had to be larger than usual due to tremendous amounts of tool pressure. In this case, the actual surface of the cutting tool/workpiece interface was 0.010-inch farther out than the actual machine position. The need to have a 0.012-inch buffer between pecks increased the actual feed travel to 1.498 inches. This meant the machine had to feed a total of six times the actual depth of the groove. The slow nature of this process was exacerbated by the need to peck.

Table 4 presents the optimal process parameters and response values obtained from 22 runs with a population size of 100 and 100 iterations for all algorithms. Table 5 shows the statistical significance of these algorithms.

Each valve body features two ring grooves. These features alone would’ve taken two hours to produce on the manual engine lathe during reconditioning applications.

Another problem was the machine’s low speed. It simply didn’t have the torque necessary to efficiently machine all layers of the material, and it would rumble and beat everything up, Mr. Hylton says. He often used three carbide insert tips during the process, requiring him to stop, pull the insert, change it and hit cycle start again. The entire grooving process took between 47 minutes to an hour to complete. To make matters worse, Mr. Hylton says that sometimes the insert would break randomly; there was no consistency at all.

The efficiency of ALO is compared with GHO, GWO, and HSA. ALO shows superior performance in end milling applications, achieving optimal parameter settings at a lower iteration, as illustrated in the convergence plot (Figure 13). The TOPSIS approach integrated the output responses from 22 runs into a single objective, confirming the normal distribution of output data from all algorithms. The p-value of > 0.05 further substantiates the reliability and consistency of the ALO results.

Tool-holder-spindle-machine combinations each have a unique dynamic response in the same way that each person has a unique fingerprint, which can be revealed using modal testing.

Figure 4 demonstrates that cryo-treated cutting tools outperform untreated inserts in terms of cutting temperature.

The surface plot of SR vs FR, SS in Figure 8 illustrates the effect of process parameters on surface roughness. Initially, the surface roughness was higher, but as the cutting speed increased, it decreased and then increased again. Surface roughness rises in dependence on the FR. According to the Pareto chart in Figure 9, spindle speed and feed rate significantly influence surface roughness. The production of built-up edges (BUE) at specific spindle speeds reduces Ra. The SEM image in Figure 10 shows imperfections and micro-voids on machined surfaces caused by carbide particles and BUE. Cryo-treated inserts perform better, reducing heat generation and improving surface finishing. (39).

Each tool setting technique has merit, and it depends on where you are as a shop and the type of work you do, as cost and efficiency all come into play.

When attempting to determine the best pairings between two sets of data, it can be helpful. By drawing an analogy with a topographic map, the color and patterns in Surface Charts show the places that fall within the same range of values. Three variables are often used to generate a 3D Surface Plot: X, Y, and Z. Surface plot for CF.

The study aimed to optimize milling parameters such as spindle speed and feed rate to minimize cutting force (CF) and surface roughness (SR) using Grasshopper Optimization (GHO), Grey Wolf Optimization (GWO), Harmony Search Algorithm (HSA), and Ant Lion Optimization (ALO) algorithms. Key findings, based on the Multi-Criteria Decision Making (MCDM) method, are summarized below:

TNG also uses ceramic inserts on its bread and butter work of cutting valve seats in 410 stainless with a Stellite overlay. According to Mr. Hylton, this application is tricky because the groove goes through the Stellite, then through the heat-affected zone and down to the base material—an application that requires cutting material ranging from 40 to 67 HRC.

Heidenhain and Acu-Rite Solutions are offering several hands-on experiences at their booth this year, as well as internal components that reduce energy use.

The experiment involved end milling Custom 450 stainless steel in a dry, room-temperature environment using cutting inserts that were either untreated (UT), cryo-treated with 24 h of soaking (CT 24 h), or cryo-treated with 36 h of soaking (CT 36 h). This was conducted on a CNC vertical machining centre as shown in Figure 1A. The dimensions of 160 mm × 75 mm × 20 mm (4 numbers) were prepared. The chemical composition and mechanical properties of Custom 450 stainless steel were determined (31). The tool holder used was a standard indexable type (Diameter: 16 mm, Length: 150 mm), and the cutting tool insert was a TiAlN-coated tungsten carbide insert (APMT1135PDR YBG205). The primary cutting parameters employed in this study were spindle speed, feed rate, and depth of cut. (31).

• The quadratic Multiple Linear Regression Model (MLRM) equation proved to be the most accurate for end milling, surpassing interaction and linear models.

This was especially true for TNG Energy Services Inc., a geothermal company that provides both equipment and services from its Bakersfield, California, headquarters. The company’s mostly JIT workload along with meeting strict quality control requirements led its employees to work large amounts of overtime. This was due, in large part, to the challenges  of machining grooves in valve components for oilfield applications using conventional carbide inserts. By switching to ceramic inserts from Greenleaf Corp. (Saegertown, Pennsylvania), TNG was able to dramatically reduce cycle time for two valve applications, meeting deadlines without the additional overtime costs.

TNG’s most common work is cutting valve seats in 410 stainless with a Stellite overlay. A face grooving tool with Greenleaf’s new Xsytin-1 ceramic inserts and a support blade help cut through all layers in this application.

Evolutionary algorithms have been utilized to optimize the various machining processes (Kalita et al., 2020; Kalita et al., 2022; Kalita et al., 2023a; Kalita et al., 2023b). Adhesive wear on the studied surface was characterized by deformation lips, surface cracks, and fractured ridges, with Particle Swarm Optimization showing promising results for increased efficiency (Katoch et al., 2019). (Manjunath and kumar, 2017) demonstrated that face milling with cryo-treated tools can reduce surface roughness. The work in this paper was theoretically validated by creating a prototype using the BONN technique and real-time experimental data. The optimization was conducted using a MATLAB Genetic algorithm solver. The analysis of the direct and indirect effects of process parameters on temperature rise assisted in selecting parameters to minimize temperature increase, indicating the stability of the end milling process. The study’s predictive models for temperature rise are expected to align within a 95% confidence interval of the experimental results (Kaushik et al., 2018). Drilling on polymer composite material varied three process constraints at four discrete levels: spindle speed, feed rate, and weight percentage of graphite. The Taguchi-Grey Theory-Based Harmony Search Algorithm (GR-HSA) was used for multi-objective optimization and predictive modelling. The results showed that the machining interface temperature increased with GR-HSA spindle speed (2,500 rpm), softening the polymeric material in the machining zone (Kumar et al., 2021). In multi-pass face milling processes, parameters were optimized using HSA and compared against HA and GA algorithms (Zarei et al., 2009). The application of ant lion optimization in spacecraft attitude controllers demonstrated the ability of the suggested control action to prevent unnecessary long manoeuvring paths, enhancing resistance to unwinding (Amrr et al., 2019). The forms of two ship propellers were optimized using ALO, presenting superior optimal designs in 3-bar truss design, cantilever beam design, and gear train design. The ideal forms for ship propellers illustrate the potential application of the proposed approach to solve real-world problems with unpredictable search areas (Gao and Zhao, 2019). An enhanced grey wolf optimization technique was compared against algorithms like ALO, PSO, BA, regular GWO, and others, showing superior performance in high-dimensional situations (Khalilpourazari and Khalilpourazary, 2018). (Khalilpourazari and Khalilpourazary, 2018) suggested the GWO for optimizing multi-pass milling process parameters, using the Taguchi technique to find optimal values for the algorithm’s essential parameters (Shunmugesh and Panneerselvam, 2017). The results showed that the GWO outperforms other solutions by reducing total production time and offering the most workable solution for different cutting strategies (Niu et al., 2019).

Harmony Search Algorithm (HSA) (Yang, 2009) operates with minimal mathematical constraints and does not require a predefined dataset for parameter selection. It draws an analogy to artists seeking harmonious music, with engineers seeking global solutions determined by an objective function. The process involves adjusting pitch and considering evolutionary algorithm modifications to achieve optimal conditions. The main principles of Harmony Search Process are: choose initial information from search memory (memory-related concerns), select the closest value from the harmony search memory (pitch modifications) and randomly select values from the range of potential values. The HSA algorithm is shown in Algorithm 3.

The groove is produced in one shot, eliminating the finish pass as well. When TNG started using the ceramic face grooving tool, Mr. Hylton says he was nervous. He questioned his Greenleaf representative about his suggested cutting speeds. However, he says his fears were soon calmed when he saw the Stellite coming off like powder. The ceramic face grooving tool can cut the groove in 30 to 40 seconds.

Previous research has focused on identifying the ideal level of machining parameters for CNC milling operations, often employing artificial intelligence approaches like genetic algorithms (GA), artificial neural networks, and fuzzy logic. Commonly enhanced input parameters include feed rate, depth of cut, and spindle speed (Jia et al., 2012). However, limited research has been conducted on using the length of the cryogenic treatment soaking as a process parameter to achieve optimal machining parameters. Only a few studies briefly mention the use of deep cryogenic treatment (DCT) to enhance tool life, often focusing on single objectives like tool wear and flank wear. Additionally, little work has examined the impact of cryogenic treatment on the material of cutting tools. Thus, providing a robust technological model to enhance the process’s productivity is crucial. To address this gap, experimental tests were conducted to investigate the impact of cryogenic treatment on end mill cutters on the cutting force and temperature of Custom 450 stainless steel using a CNC end milling process. These steels are particularly useful in industries such as medical, food, nuclear power, and chemicals, where precise machining into complex aeronautical fittings, aerospace components like shafts, valves, and specific screws, cabin components, and landing gears is essential (Kuntoğlu et al., 2020; Kuntoğlu and Sağlam, 2021; Korkmaz et al., 2023a; Binali et al., 2023; Korkmaz et al., 2023b). CNC end milling was carried out on a vertical milling machine. Various soaking times (between 24 and 36 h) of CT were applied to tungsten carbide end milling cutters. A scanning electron microscope (SEM) was used to investigate the chip and surface morphology of the cryo-treated and untreated tools. SEM (Vickram et al., 2021; Palanivelu et al., 2022; Raj Deena et al., 2022) imaging finds widespread utility in various fields.

Now, the company uses a face grooving tool with Greenleaf’s new Xsytin-1 ceramic inserts and a support blade. According to Greenleaf, Xsytin-1 is a phase-toughened ceramic insert grade that is showing promise for a wider range of materials than traditional ceramic insert technology, bridging the gap between conventional carbide and ceramic inserts for exotic materials, as well as more conventional metals such as mild and stainless steels. The company says its proprietary phase-toughening ceramic manufacturing process developed for this coating-free grade results in predictable, wear- and thermal-shock-resistant inserts that are twice as strong as the company’s WG-300 whisker grade. It also enables the generation of a sharper insert edge, which can lead to reduced tool pressure and better surface finishes.

Grasshopper Optimization Algorithm (GHO) is inspired by the nymph and adult stages of grasshopper life (Meraihi et al., 2021). The nymph stage involves short, leisurely steps, while the adult stage features long, rapid movements. These behaviors underlie GHO’s intensification and diversification phases. In the exploration phase, GHO updates the position value of each grasshopper in the swarm and evaluates fitness, symbolizing the search for food sources. During the exploitation phase, it identifies the optimal solution among all options, akin to seeking better food sources.

• Analyses indicate that spindle speed, feed rate, and cryogenic treatment are critical in milling. Increases in these parameters correspond to higher CF and Temperature (TT).

The Multiple Linear Regression Model (MLRM) can be employed in mathematics to calculate the response value (the output) in terms of several parameters (the inputs) (Shanmugasundar et al., 2021a). This study establishes three variants of the MLRM equations—linear, quadratic, and interaction—using experimental data and MATLAB’s “regress” function. These three models are represented in their standard forms as Eq. 1, Eq. 2, and Eq. 3:

Here, a is the number of algorithms, r is the number of runs, and Rj represents the ultimate rank for each algorithm. The test statistic is compared against the F-distribution table value. If the computed Ff is higher than the table value, the result is considered significant.
