Is there a way to adjust the RPM during the enty move? using NX 8.5.3
Helix to 1st depth
mill at 1st depth
Helix to 2nd depth
mill at 2nd depth
Well for a good answer you need to provide a little more info.
In that example you're doing a helix with 50% speed. You can make the post always spit out a S3000(or 50%) on a helix move, then S6000(or 100%) on the cutter comp move.
But do you need this to be on helix moves only, always 50%, does this need to be able to be be turned on and off?
As I understand it, you want to define an Engage Speed, similar to how the system has an engage feed.
You need to set something in NX, and then handle it in your post.
In NX, as @aluminum2 suggested you can create a UDE for engage speed and set it there. This will provide a specific event for the post.
I think I would try the Text Status seen below Spindle Speed in the Feeds and Speeds dialog. This is used to append minor words to the legacy CLS SPINDL command, but it stores a text string so put whatever you want there to flag something for your post. For example, I entered "engage RPM 6543", and you can see the mom variable:
Var: mom_spindle_rpm = 12345.00000000000000000
Var: mom_spindle_mode = 0
Var: mom_spindle_range =
Var: mom_spindle_text = engage RPM 6543
Regardless of how you indicate this in NX, you will need to set up your post to handle it by either checking for your new UDE, or checking the contents of mom_spindle_text. When the engage motion starts, do your check and output a new M3Snnnn if needed. Then at the end of the engage motion, set the speed back to mom_spindle_rpm.
Other options (may not work in this case, as engage is part of cut)
- Avoidance points + *_marker UDES + "Extra Spindle On" UDE
- (very obscure) You can attach start/end UDEs to boundary elements (curves or whatever) similar to stock. True in planar milling & turning, not sure about some of the other operation types
Production: NX10.0.3.5 MP16/TC11.2
I'd rather be e-steamed than e-diseaseled
Thanks Ken. edit tool path / ude / insert worked. this will get me thru the job. i will look into creating a dedicated ude for the long term like eveyone above mentioned.
