Thread Mill cutting method

[Matthew Hajicek - Singularity]

Tool-edge feed rate would be useful in just about every toolpath, I think.

AMW, I'll pass this thread on to the product owner.

Just a note that 2025 has received a bevy of Thread milling enhancements developed in concert with tooling manufacturers. Check out the Gradual entry on the lead in/out page to reduce shock load on engagement and the expanded entry/exit controls and speed/feed overrides, among others. Spindle direction is also now considered when displaying cut direction in the Machining direction box.

Here's the full list of changes:

Yeah it would be nice to have a choice of how depth cuts are handled. Thanks for passing on the suggestion.

This is long over due, but welcomed.  Any chance this will roll into the regular contour paths?  it would be extremely helpful to optimize feed rates in corners while maintaining the actual programmed feed rate.  I know this can be done locally, but it is a real PITA and should be handled inside MC.

 

We're aware of how useful this can be elsewhere and are looking at how we can implement it. That's why we placed this edge feed rate control in the Tool page rather than sequestered away in a threadmill specific page.

I'm not sure I understand your drawing right (probably just me being ignorant), so I attached a drawing similar to yours. I left my axis viewport on so you can see my Z axis for orientation. I want to start at 1 and thread Z+ for 1 revolution to 2 for my 1st cut. Then start at 3 and thread Z+ for 1 revolution to 4 and so on. With separate operations I could accomplish this but if I want multiple radial cuts (like threading on a lathe) I'd have to make even more operations which is time consuming. Maybe MC can implement this easily, I don't know.

 

For those that want to know my enhancement request number is D-08469.

A Thread Mill operation can be completed, but the steps are a bit troublesome now...

Maybe it will be more practical to wait for Mastercam to support radial and depth in the future.
