Optimized tooling choice for any material depends greatly on the grade of the material. For example, in steels where chip evacuation is a problem area, flute count can be optimized with greater flute count or a higher helix. Knowing the grade allows for appropriate tool choice, workholding, and fine-tuning of the operation for optimal efficiency.

Usually, tolerances are numerical measurements of a product’s X, Y, and Z dimensions. Here are some common terms for describing the various elements of a component’s dimensional tolerance:

Loose tolerances allow for more leeway, which can be more affordable — but overly loose dimensional tolerances can compromise precision and usability. To achieve optimal tolerance, you must strike the balance between cost-effective production and necessary precision for functionality.

Imagine you order 50,000 components for a new project, and half arrive 0.2mm too small. For some parts, this variation wouldn’t matter, but for your specific part, the disparity renders half of the parts unusable. Now you have to try and salvage the undersized parts, or start all over again. This wasted time and energy could have been avoided had you defined proper tolerances for your components early on in the design process.

The best tool materials for machining steel will offer high hardness and abrasion resistance for faster cutting and longer tool life. Carbide and high-speed steel are both excellent options.

What ismachining

The more deeply you consider manufacturing materials, design for assembly, and other elements of design and production, the more precise your dimensional tolerances and fits will be. A strong dimensional tolerance analysis process will help you determine your component’s optimal tolerances, helping ensure your parts are built efficiently, reliably, and fully functional.

Typically, crystals in CVD alumina coatings are aligned randomly, which leaves weak areas susceptible to cracking. InveioTM Technology from Sandvik Coromant is the innovative answer to improved removal rates. Designed specifically for the mass-production processes involving steels, InveioTM Technology creates unidirectional crystal alignment in the coating to improve wear-resistance and performance at high speeds and temperatures. The 4400 series offers a broad application range while allowing higher speed cutting and longer times in the cut due to heat resistance and toughness. When it comes to milder steels, there are a variety of chip-breaking geometries available.

It’s particularly important to have accurate dimensional tolerances for 3D printed moving parts, because even the smallest deviation could lead to a size disparity that causes incompatibility — and this could potentially happen to a lot of individual components. Accounting for dimensional tolerances in your design will help remove ambiguity from the manufacturing process, ensuring effective manufacturing and ultimately, high-performing parts.

Effectively tolerancing a given part requires weighing a number of relevant factors and doing your due diligence to ensure you’ve assessed potential risks and benefits accordingly. It can be a tedious process and may involve a range of unpredictable considerations. To simplify and streamline the process of tolerancing — and, more broadly, to better optimize your designs — consider partnering with an on-demand manufacturer like SyBridge.

To cut any material efficiently, you must consider certain key characteristics of both the work piece and machining tool. But, with all these variables in play, how do you know the best way to cut a specific metal?

Problem: One of the main issues with high carbon steels involves high cutting forces because – you guessed it – high carbon steels are even tougher to cut than mild and medium steels.

Of course, there will always be deviations in a component’s dimensions due to manufacturing errors and natural, unavoidable variations in materials. The point of creating tolerances isn’t to avoid these errors completely, but rather to account for these variations and control for them. Tolerances that consider physical limitations of material and manufacturing methods can help you feel confident in the production consistency of your part.

Of course, without diving into each type of steel individually there is only so much that can be said about their specific machining processes. However, having a basic understanding is the first step in developing a stronger machining strategy that could result in time (and costs) saved in the long run. If you’re ready to take your operation to the next level with an in-depth evaluation of your steel machining processes, contact Triumph today!

Machiningdefinition in manufacturing

Creating tolerances is crucial to the success of your product, but it can be as complicated as it is essential. When deciding on a component’s tolerances, you must consider every physical property of the design, every step in the assembly process, and every potential application of the final product. Here are some common mistakes product designers, developers, and engineers may make when creating tolerances for their components:

Machiningprocess steps

Consider: Heat and vibration can be minimized by adjusting cutting data, using coolant, adjusting workholding and toolholding, and selecting the right tool for the job.

A part’s tolerance can be either “tight” or “loose,” depending on how exact a component’s measurements need to be. Tight tolerances allow for very little lower and upper deviations, which makes them precise but expensive, as they require specialized manufacturing equipment.

Dimensional tolerances can be applied to any element, including color, texture, temperature, and shape, as well as natural phenomena like corrosion.

Problem: Mild steels are soft and known as “gummy”. This can pose quite an issue for the machinist, as soft steel produces long chips that can easily impede tool path if not removed properly. Another common issue with mild steels is built up edge. Because these steels are soft, material tends to build up on the cutting face of the tool which can significantly impact cutting ability.

Here at Triumph Tool, we provide machining solutions that help you save time and money, which is why we’re introducing our Machining 101 series! In Machining 101, we’ll cover the things you need to know to make informed decisions about tooling and machining processes. For the series kickoff, we’re starting with steel. Now, you may be thinking – does this include stainless steels? We’ve decided to cover stainless in a separate post, so stay tuned!

As mentioned, there are more than a few factors to consider when machining metals. The “condition” of the work material is the combined set of characteristics which affect machinability. On top of this, you must also consider factors on the machine side, which together impact the efficacy of metal removal.

A large part of wear resistance comes down to tool coating. So, what’s the best tool coating for steel? Generally speaking, CVD coating with AlTiN is often used for roughing/semifinishing processes. PVD TiAlN coatings tend to be the most popular for dry high-speed finishing as well as general machining. Finding the best coating for your process depends significantly on the type of steel being used, but the new Sandvik Coromant 4400 series is a great place to start, at least for turning.

Finishing or post-processing — such as coating or electroplating — also impacts the tolerance band of a given component. Being unaware of these steps, or simply overlooking them in the design and prototyping stages, may result in mismeasured tolerances.

Within each type of steel lies subcategories of steel – like low, medium, and high carbon steels; ferritic and duplex stainless steel alloys; aluminum, molybdenum, and silicon alloy steels; as well as oil-hardening, high-speed, and air-hardening tool steels.

Consider these factors when selecting your tooling and process setup. Your machining efficiency will improve significantly.

The other thing that must be considered is the process at hand – roughing vs. finishing, turning vs. milling, etc. Because tooling choice varies by process and type of steel, the best thing you can do to optimize your cutting operations is to speak with a Triumph Technical Sales Representative. With each coming from machining backgrounds, they can offer tooling solutions ranging from Good, to Better, to Best to find the right fit for your application.

Steel is unique in the sense that it’s extremely versatile. As an alloy made up of multiple different elements, steel has a broad range of applications that differ depending on the type of steel being used. One of the main factors to consider when machining steel is that it’s strong, even at high temperatures. That said, because steel has such a broad range of characteristics every type will react differently. What does this mean for machining processes? You need to adjust accordingly!

It’s important to identify tolerances as early in the design process as possible. This allows you to keep key considerations in mind throughout the entire product development lifecycle. Here are five steps to help you determine tolerances:

Problem: Because medium steels are stronger than mild ones, they’re (not surprisingly) more difficult to cut. This often leads to issues with heat and vibration.

It’s easy to simply create tolerances that are too loose or too tight. Additionally, it’s common to ineffectively gauge environmental factors like surface roughness and mold temperature, which can greatly affect your tolerances. Consider application requirements, performance expectations, and environmental factors early on in the design process. Otherwise, you may risk remanufacturing components — which can lead to increased costs, time, and resources.

Tolerances are crucial to ensuring your parts fit together to form a successful final product. You’ll want to measure your tolerances as best you can — the most accurate dimensional tolerance analyses will account for margins of error without demanding expensive over-precision. Striking this balance will ensure you use only the necessary manufacturing materials, tools, and labor, mitigating production timelines and costs.

Consider: With long chip forming materials feed rate, depth of cut and insert geometry are extremely important. With drilling and boring processes, coolant access and tool geometry can be specified for chip removal. Even mild steels react differently depending on the process and conditions. This is where a Triumph Technical Sales Representative can help you find the proper geometry for the job!

Consider: Higher cutting forces means one thing above all else – greater load on the tool. So, when you’re working with tough steels, tool wear needs to be considered to achieve a balance between toughness (which will provide great metal removal) and wear resistance (which prolongs tool life). This is a delicate balance that our Triumph Technical Sales Representatives would be happy to help you navigate. On top of this, lower cutting speeds and reduced cutting depth may be necessary to minimize tool load.

If you don’t specify your tolerances, your manufacturing team or vendor could place their own tolerances onto your component, which could result in improper sizing and unusable parts.

Dimensional tolerances are a crucial part of the design and manufacturing process. A tolerance is a numerical range of measurements assigned to a part’s dimensions indicating how much a manufacturing team can drift from the nominal measurement. Spending time on proper tolerancing pre-manufacturing can lead to a quick, efficient build.
