Approach feedrate
Approach feedrate
(OP)
In the engage moves in Cavity mill, we use arc. There are parameters like arc radius, arc angle height, minimum clearance. We set the height 0, because the engage feedrate is 100% of Cut feedrate. When the feedrate is 21000mm/min, it would be great to define a lot smaller feedrate for this axial engage move. If I set the 'approach move feedrate' to ie. 2000mm/min, then the tool comes from the clearance plane verry slow.
Can we somehow implement it?

In the top of the image, there can be collision, the high engage feedrate in axial move can damage the tool in ie. an island contouring.
In the second case, the tool comes from the clearance very slow.
In the third case, what I would like to get, a high speed or rapid axial approach near the part, then a slow axial infeed move, then the normal to tool-axis arc with cutting feedrate.

Collision checking is on, approach is rapid, engage feedrate is equal to cutting feedrate (ie.8000mmpm)
When the tool engages outside the part, the engage move is a simple arc. Correct.
When the toll engages the finish pass, there are in the attached picture two different cases.
The first, when there is a rapid approach till the part face. I say nothing..
The second, when there is a small axial engage, but there it should be reach the surface much slower then the above engage feedrate (ie. 500mmpm).
I cannot separate them, thats my pain.

It is 2013..........I expect more out of NX than what it is giving me.
Thanks for your hard work. diamond3210 and kukelyk, but this is getting ridiculous.

To the Toolmaker, your nice little cartoon drawing of your glass looks cool, but your solid model sucks. Do you want me to fix it, or are you going to take all week to get it back to me so I can get some work done?

Goto points and fake feeds are the only way to do what you need to do now.
We have neen kludging this weak cavity mill function for many YEARS......when is some maintenance $$ going to be put into fixing Cavity Mill?

Btw, we are not allowed internet access from work (don't ask...) so I have to use my phone for this stuff during the day. Hard to show you examples :( Maybe attach a phone screen shot if you still need help.
Hope this helps.
