What’s so “Dynamic” about Dynamic Motion?

We were recently talking with a representative from a tooling company. He was familiar with Mastercam’s Dynamic Motion, having seen it in several shops and even having used it to help make his tools look their best. The thing he liked most about it, he said, was the consistency. Consistent chip load, constant step over, spindle speed, consistent performance. Then he asked this:

“With everything being so consistent with those toolpaths, what exactly is dynamic about them?”

It’s a great question. Why do we call these toolpaths “dynamic” if they have such a predictable outcome? The answer is straightforward. Every tool has an ideal cut condition if it were to travel in a straight line. It would maintain consistent chip load during this safe cut condition. Mastercam’s Dynamic Motion technology works to apply those conditions to an entire toolpath, not just a straight-line cut. The result is constantly changing motion that adjusts itself to best reflect that ideal cut condition and create a consistent chip load on the tool.

Let’s take a look at the example below.

As you can see, the toolpath itself varies widely from area to area, and even within any one given section. But the output – the chip load – is the same in each case.

And that’s the answer – Mastercam’s toolpaths use Dynamic motion so your results can be consistent.
