“We’ve been reluctant to treat this interrupted cut as an operation that allows the operator to walk away,” Mr. Caskey explains, “So when this part is in production, it gets special attention in scheduling.”

To say that this insert grade turns concepts for production turning on their heads is more than a figure of speech. Developers at Sandvik Coromant accept this characterization because the most innovative feature of this grade is how the grain structure of the aluminum oxide crystals in the coating are arranged. This helps create a cutting edge that is both exceptionally long-lasting and highly predictable in its wear patterns.

For another, the company has developed methods to produce an edge-line with a highly uniform radius. With most known methods on the market, this radius varied as much as ±15 microns from the normal. Now, the deviation band is less than one third as wide. Greater uniformity enhances predictability of edge performance and helps it retain its sharpness.

Company officials did not indicate in which direction they will take these developments in the short term. Clearly, they intend to emphasize products that address the needs arising from the changing environment in manufacturing.

3. The most important feature of the insert’s structure stands out as exceptional and original. This is the nature of the crystalline structure within the layer of aluminum oxide. In this structure, the crystals are arranged unidirectionally with the longest facets in a near parallel position. In addition, all of the crystals are oriented with the densest atomic plane toward the cutting surface. This “heads up” orientation makes the aluminum oxide layer very hard, so it resists wear exceptionally well. At the same time, this orientation enables this layer to act as a barrier to heat from the cutting zone. The dense atomic plane nearest the surface deflects heat into the chip and coolant. Meanwhile, heat that is absorbed by the insert is readily conducted to the less dense atomic planes nearest the TiCN coating, where it dissipates into this coating and the substrate underneath. By preventing the buildup of heat, this layer forestalls plastic deformation because the surface of the insert does not get hot enough to lose its original shape.

New Grade Crystallizes Sandvik Coromant is calling the GC4325 a notable achievement in insert technology because the company has been able to give the grade properties unattainable with previous manufacturing methods. These properties, the company contends, account for the insert’s advantages in P25 steels.

Predictability has become increasingly important in today’s machining, especially where there is limited supervision in production.

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.

In the latest episode of our View From My Shop series, MMS Editor-in-Chief Brent Donaldson visited the JN Shapiro Watches headquarters and production facility where Founder Joshua Shapiro—a history teacher turned watchmaker—realized his dream of "making a watch from scratch and everything in it."

Observation of insert behavior finds that the optimum wear pattern for any insert is controlled flank wear because it protects cutting edges. Flank wear is caused by abrasion of the clearance face below the edge-line. The abrasion results from the passage of the chip as it forms during cutting action. Flank wear is the natural depletion of material, and is acceptable to the extent that other wear modes are kept in check.

Although the new grade is intended for P25 steels, GKN Walterscheid was encouraged to test the inserts on a turning application in which cutting tool performance was particularly troublesome. Team Leader Luis DeAnda suggested testing the inserts on a facing operation that finishes the bottom surface of a driveshaft yoke. The yoke is produced in 80603 ductile iron. “Surface finish and part size are critical for this operation,” explains Mr. DeAnda. “We produce this yoke in large volumes. Typically, the facing operation runs on Mazak turning centers in six-machine cells.”

Researchers say that to be successful, turning operations in the P25 steel range must address and balance many factors. Of utmost importance is maintaining the condition of the edge-line. Unless the edge-line remains intact, rapid breakdown occurs, resulting in unacceptable parts and loss of machining security.

The problem with this facing operation was that insert edges were set to be indexed after four hours of cut time, but after two or three hours, results with the inserts became unpredictable. Edges on the inserts, a GC4215 grade, often lasted the full four hours to produce approximately 80 pieces, but oversized parts or poor surface finish began showing up frequently after only two hours of cut time. In response, a third operator, if available, was assigned to monitor this operation in the cell. The main duty of this operator was to change inserts when premature wear was detected, Mr. DeAnda reports. “If an extra operator wasn’t free to help, inferior results on the facing operation jeopardized subsequent machining operations, creating a chain reaction that led to reduced tool life in those operations as well,” Mr. DeAnda explains.

For a third, the top surface of the finished insert is subjected to a final “post treatment” that smooths and blends its texture while removing the TiN coating where it is not needed. In addition to producing a smoother, “crack-free” texture, this treatment alters residual stress between coatings and substrate. Tensile stress is reduced; compressive stress is enhanced. The result is tighter adhesion between the remaining coatings and substrate.

Initial tests show that the new insert provides 45 to 55 percent improvement in edge life, depending on trial settings of speeds and feeds to optimize results. More importantly, performance of the new grade indicates that it is especially tolerant of the repeated impacts created by an interrupted cut. “We are close to finalizing the machining parameters that make this operation one that doesn’t need close watching,” Mr. DeAnda adds.

Ms. Pålsson also notes that three other aspects of the manufacturing process contribute to or support the functionality of the special nature of the aluminum oxide layer. For one, the structure of the carbide substrate features a gradient zone that acts as a thin outer layer that is slightly softer than the inner core. This layer acts like an impact-absorbing padding for the coated layers. The inner core of the substrate, however, retains its tough, wear-resistant properties derived from the fine grains of tungsten carbide and cobalt binder.

Across a range of technical presentations aimed at small and mid-sized job shops, the first-ever Automated Shop Conference (TASC) offered insights into several automated technologies, implementation strategies, shopfloor training tips, and even the untapped power of automated coolant delivery.

When the GC4325 inserts were substituted on this facing operation, edges consistently produced 120 parts, a 50-percent increase, at the same speeds and feeds. “We were changing these new inserts because of flank wear, not because the edge-line was chipping or dulling,” Mr. DeAnda says. It was clear that the new inserts were undergoing wear in a controlled and predictable manner. This gave Mr. DeAnda confidence that the facing operation did not require the special attention of an added person tending the cell.

A long-lasting cutting edge and controlled wear rewrites the formula for turning operations in this workpiece material. It greatly lessens the negative trade-off between metal removal rates and tool life, thus making many turning operations significantly more productive. Likewise, it makes these operations more compatible with automated, lightly supervised machining resources.

Ideally, a turning insert grade for P25 should exhibit only limited flank and crater wear and avoid all other wear modes.

The ideal wear characteristics for any insert are slow, controlled flank wear and minor cratering on the face. Signs of discontinuous wear, such as edge chipping, flaking of the coating or plastic deformation, should be missing entirely. The enlargement of a worn GC4325 insert shown here exhibits those characteristics.

Misapplication of these important CNC features will result in wasted time, wasted or duplicated effort and/or wasted material.

One of these manufacturers, GKN Walterscheid in Woodridge, Illinois, reports a significant gain in productivity with this insert grade. In one test, these inserts outlasted previous insert choices by 50 percent. (Sandvik Coromant indicates that these results are typical for the entire test group, which includes numerous shops in the United States and Europe.)

2. How the substrate and coatings are combined involves proprietary innovations developed in Sandvik Coromant’s R&D centers. Product engineers say these manufacturing methods create an advantageous synergy among the insert’s features. You cannot disturb or remove any of their properties without diminishing the total effectiveness of the insert.

Though most frequently used for diameter measurements, an air plug and platen can be readily configured to measure perpendicularity.

Because steels in this category are frequently encountered in high-production turning applications, process variables are critical—especially in the choice of turning inserts. Many factors must be addressed and balanced when selecting the insert grades intended to yield optimal results. In the past, process engineers made strategic trade-offs between material removal rates, tool life and risk of process disruptions.

Most recently, GKN Walterscheid began testing the GC4325 inserts on workpieces on a heat-treated 1045 steel workpiece. This part, a heavy-duty driveshaft yoke, requires turning operations that include an especially difficult interrupted cut. Depending on the batch size, the part runs on one or more Mazak turning centers equipped with a dedicated two-jaw chuck. The machines are arranged in a cell.

Overall, results such as these confirm that this new grade provides superior results because it is resistant to discontinuous (and therefore uncontrollable) wear patterns, and undergoing mainly flank wear and some crater wear. “This means the edge-line is holding out for the life of the insert and that we can safely run more turning operations in our lightly manned cells,” Mr. DeAnda concludes. Mr. Caskey concurs. “With our machines arranged in cells, every boost in turning productivity is magnified, especially when fewer operators are needed to keep the cells running,” he says.

FANUC’s IMTS 2024 booth includes real-time demonstrations that show the abilities of its equipment, including robots, controllers and machine tools.

Designing a turning insert grade for steel in the P25 classification is particularly challenging because both the material and applications vary widely. The operations involved include roughing and finishing on out-of-round or near-net-shape cast or forged workpieces. Steel materials in the P25 range may be unalloyed or highly alloyed, with hardness values that differ substantially from one end of the range to the other. For a single insert grade to perform in the face of these many variables, it must have certain characteristics. For example, fracture resistance is paramount, as is a cutting edge possessing the hardness to resist plastic deformation induced by the extreme temperatures encountered in P25 cutting zones. Furthermore, the insert coating must adhere tightly to the substrate. If the coating fails to stick, exposed substrate deteriorates rapidly.

Q-Mark has built its metrology business by providing what customers need, when they want it. This goes for its IMTS booth, too, with free drinks alongside custom technology.

Sandvik Coromant, for example, has been focusing on promising developments in insert technology specifically targeted to P25 turning applications. The result of these development efforts—a new grade of turning inserts for P25 steels—is already in the hands of selected U.S. manufacturers as part of the company’s final field testing and evaluation procedures. The new grade is designated GC4325.

When an insert undergoes only continuous, controllable wear, its performance will be consistent and predictable. In contrast, discontinuous wear is caused by scattered, discrete events such as the appearance of a surface crack, plastic deformation or flaking of the coating. The effects of discontinuous wear are difficult or impossible to control.

Standards for surface finishes and profiles are not static; they change as technology changes or new processes come along that need to be considered.

A Many-Faceted Prospect Sandvik Coromant officially introduced the GC4325 insert grade at EMO in Hannover, Germany in September. The announcement focused on its benefits in P25 applications. These applications cut across many industries and represent a significant market for coated carbide insert grades. However, the challenges associated with these applications are not unique to production turning applications. Advances in this area have significant implications for many other machining processes that use coated carbide inserts, including milling and other categories of steel or iron workpiece materials.

User-friendly inspection software for CNC machining centers is shown monitoring measurements between and after machining while performing SPC based on recorded measurement values.

More than ever, shop managers are aware that increasing output while lowering labor input is the most effective way to boost productivity. Profits naturally follow.

Understanding all the things that contribute to a machine’s full potential accuracy will inform what to prioritize when fine-tuning the machine.

Understandably, Sandvik Coromant is not divulging many specific details about the techniques by which the aluminum oxide layer is induced to form this unique crystalline structure. Mia Pålsson, product manager for the GC4325 grade, explains that successful production of these inserts hinges on advanced control of the chemical vapor deposition (CVD) process that forms each layer of the coating.

When revising part designs, investigate the 3D CAD, the 2D drawing and the part’s functional requirements to determine which details should be tightened up.

“For certain critical turning operations that require frequent insert changes, we usually add an extra operator to keep up or react to unexpected tool failure. Inserts with reliably longer lasting cutting edges enable us to stick to one operator for every two or three machines,” says Scott Caskey, manufacturing engineering manager at GKN Walterscheid.

More important, this user is now evaluating how it can implement fundamental realignments in its approach to production turning. For example, GKN Walterscheid relies on machining cells consisting of multiple CNC turning centers that are intended to be monitored by only one or two operators.

Today, however, an overriding consideration often is how to accommodate processes that take advantage of turning equipment designed for low operator involvement. The operator may be present, but assigned to monitor and tend multiple machines. Or, the operator may not be present at all, having set up the machine for operation through an unattended shift, overnight or over the weekend. In these settings, the reliability and predictability of the cutting tool’s performance take on heightened importance.

When Puneet and Neelam Neotia moved from India to the United States several years ago, they brought with them a family background in manufacturing and CNC machining. Now the couple is working to get their startup machine shop off the ground, sourcing new customers and getting the word out about their shop in Clarksville, Indiana. The couple — proud to publicize their "Made in the USA" parts — is leveraging family connections and manufacturing capabilities back in India, but not in the way that some people assume.

Machine tools is an integral part of the manufacturing industry, and directly impacts the economy of any country. The machine tools sector in Africa provides numerous prospects for investment, motivated by demand from the aerospace, automotive and energy sectors. There are several new trends influencing the Machine Tools market in Africa and driving the growth of the industry going forward.

The demand for machining tools capable of handling advanced materials like composites and high-strength alloys is on the rise. Precision machining for applications in aerospace, automotive, and medical industries are becoming increasingly important.

Understanding Insert Wear According to developers at Sandvik Coromant, the GC4325 grade achieves its effectiveness because it is designed to tackle the mechanisms leading to premature breakdown. Essentially, this requires engineering the insert’s substrate, coatings and post treatment to limit continuous, controllable wear and eliminate modes of discontinuous wear.
