I'm using the hole milling operation for a particular circular pocket in my part and I was wondering if there was a way to cut the spindle speed in half while using a helical engage into my part with a square endmill. I know I can cut the feedrate in half but without the ability to also cut the spindle rpm in half my part is bound to work harden as soon as the cutter gets a little dull.
This could be achieved in post.
A UDE with either engage spindle speed or factor.
On engage move edit spindle speed to engage speed.
after engage reinstate to original.
end of operation cleanup values.
I agree but it is not user friendly.
Maybe putting this ude to operation template will be better too
I think you'll have to use UDEs (although you may want to submit an IR/ER to GTAC to add this to the operations in a future version).
I was going to suggest:
- Set the spindle speed/RPM in the feeds/speeds dialog to the RPM you want during the ENGAGE move
In the "start" events, then try adding
- "Approach Marker" UDE (I thought there was an "Engage Marker", but apparently not)
- "Extra Spindle On" UDE with the cut params
But now I don't think that will work for what you want to do (as you would need the "engage" marker).
If that is that case, you could use the "extra spindle on" but add "AFTER ENGAGE" in the text, then in the event handler, check for that text and NOT output the "S...M" right away, but check for the engage event to be over and output it before the first non-engage event.
You could also create your own UDE, which would eliminate having to putz with the default event handler for the "extra spindle on" UDE.

I'd rather be e-steamed than e-diseaseled
