Below 50% RDOC, the chip thickness changes, and the cut becomes less efficient. This decrease in efficiency can lead to tools wearing down faster than expected and poor quality finishes.

Let’s look at an example using aluminum. At around 300 SFM (surface feet per minute), the surface temperature is approximately 650c or ~1200f. The research shows that at 1000 SFM, you start seeing the same temperatures! Even more interesting, research also shows that there’s a possibility to run faster and get even lower temperatures.

The integration of CNC machining and metal spinning strategies stands as a testament to engineering ingenuity and precision craftsmanship. Envision a scenario where advanced technology

SFM stands for surface feet per minute. It’s a reference to how quickly cutting tools move across the surface of a piece in a CNC cycle. Obviously, the speed at which your tool head moves impacts the whole process.

Chip thinning generally happens when the RDOC varies. When we talk about chip thinning, we’re talking about the thickness of the chip. Chip thinning occurs when the Chip Load and RDOC are not equal.

This phrase will also sometimes show up as “Speeds and Feeds.” In the simplest definition, it refers to the cutting speed and the feed rate. These two terms are often paired up when we talk about CNC cycles, but you can also use them separately.

You’ll need to know the RPMs (revolutions per minute) of your spindle and if you’re unsure, check with your manufacturer. They will have spec sheets that deal with your particular model.

Remarkably, the initial reason HSM became a consideration was the discovery that increasing spindle speed reduces the heat in the cut once you reach a particular point. At the same time, there’s also a change in cutting forces which likely contributes to the lower heat of the cutting edge.

The benefits of high-speed machine tools are quite clear. Now, it’s time to put that knowledge into practice. With a little patience and experience, you’ll find that HSM improves milling efficiency substantially.

Even the “High-Speed” part of HSM is disputed. Although generally, HSM is understood to start at 18,000 rpm, various shops have shown that the process can work with slower spindles as well.

Have you ever wondered what high-speed machining is? Are you curious about high-speed machining formulas and definitions?

You’ll usually see this term used alongside calculations for high feed rates and high RPM operations. Feeds and Speeds calculators can help achieve excellent finishes on both sides of the tool’s cutting edge.

So how do you calculate optimal speeds and feeds? There are two main equations to use. Read on for more information on each part of the equation and how you can get the information that goes into it.

HR-SERIES metric coarse machine taps are designed for tapping difficult materials including alloy and hardened steels up to HRc52, grey cast iron, high silicone aluminium, bronze & copper alloys.

In today’s fast-paced manufacturing industry, precision and efficiency are key. That’s where CNC machining services come into play. With state-of-the-art technology and skilled operators, CNC

HSM, also known as trochoidal milling, is all about efficiency. It’s become popular over the last few years, with more and more shops adopting the practice. There have even been some advances in Machine Learning that deal directly with HSM and optimizing your tooling.

Companies tend to argue about the correct definition of HSM. Some say that the process requires quick milling passes. You may also find the very technical definition — machining at the resonant frequency of the machine. When you break it down, all this means is using spindle speeds that help to minimize chatter.

An easy way to think of this is to remember that if each tooth is working on the surface at a ninety-degree angle, our cut is most efficient. At that point, the RDOC is at 50% of the cutter diameter.

At its heart, high-speed machining (HSM) is all about increasing material removal rates while decreasing cycle time and improving tool lifetime.

The chip load, otherwise known as “feed per tooth,” is the thickness of the material that gets cut away by each tooth. The chip tends to take away some of the heat with it during the milling process.

Other machinists argue that HSM should deal with high material removal rates only. The argument here is that the true aim of HSM is to give a surface finish that’s good enough after one pass.

Although the high-speed machining formulas and definitions we’ve talked about are fairly standard, they can feel complex and overwhelming. Contact Glenn Metalcraft to discuss full-service metal manufacturing when you’re ready to explore HSM further.

When talking about the radial depth of a cut (RDOC), machine shops mean the distance a tool steps over into the workpiece. This is also sometimes called Stepover and cut width.

This article will explore some of the backgrounds of high-speed machining, how it compares to conventional machining, and touch on some high-speed machining techniques.

Beyond the definitions we’ve looked at above, there are some variables used in calculations for CNC machines that you should be aware of. We’ll discuss the formulas themselves a little further down.

We care about this, particularly because with the wrong calculations, you may end up clogging your tool teeth and increasing temperature.
