Entry Speed Setting in Helical Milling




I am a new user to NX, I am using is version 8.5, and I'm wondering if anyone could let me know if there is a way I could set the spindle speed (RPM) to a different speed during the helical entry of an operation, rather than the one already set in Spindle Speed dropdown in the Feeds and Speeds tab.


I raise this question because I see that I can set my feed rate for my engage but not my spindle speed. I know in other CAM softwares, such as MasterCam, this is part of the entry and retract steps, so I'm wondering if NX can do this as well because it can be vital to tool life and ensuring that heat is going into the chip, and not into the part or tool.

You may be able to use the approach marker and then the extra spindle UDE's

I would experiment there.

Hi Silas_M,


we are currently developing a Custom Speed & Feed functionality for Closed Area Engages (which includes your requested Helical engage).


This will be available in Adaptive Milling first (targeted release is NX12.0.2), before we'll possibly add it to other operations like Cavity Mill, Floor Wall etc.


If you have any further questions or if you are interested in testing the new functionality, please let me know.

I would expand on John's suggestion (until the NX12 stuff is available)

Set up "start" events something like this (note the RPM values are nonsense - just make them different so you know which is which):

- Extra spindle on / 100 RPM

- tool change marker

- Extra spindle on / 200 RPM

- from marker

- Extra spindle on / 300 RPM

- start marker

- Extra spindle on / 400 RPM

- approach marker

- Extra spindle on / 500 RPM



Post, and see which RPM comes out at the place you want

Then get rid of the stuff you don't need, and fix the RPM

Note some of the above markers are only active if you have avoindace points (from point or start point) defined.
