I need all you help build PostProcessor for head 4 axis CNC machine. Because now i am creating operation for head 4 axis cnc machine but no offset RTCP as image, import in machine run wrong.
I created Post processor but don't know offset pivot distance and gage length
Thanks so much!
Your machine does not support G43 Hxx or the Post does not output it?
A somewhat dangerous option in my opinion, is using the ZOFF Value on the tool ofset dialog. I don't recommend this because if someone is not aware of the offfset they will not understand why to Z values are all off. Also this will require the tools to be set EXACTLY to the correct length at the machine.
If you asking about how to program the position of the head rotary pivot centerline when you know the tool length (exact not theoretical) and you know the pivot length (exact) then there is probably a way with the "old" kinematic variables to do this. This is so rare these days that I am guessing that there may not be a way to set kinematic variables for NX to do it for you. At any rate - there is always the option of taking the mom_mcs_goto positions and doing math to set mom_pos positions in PB_CMD_before_motion in Postbuilder (replacing what NX does for you.)
Thanks all for you!
I have found the cause and how to offset pivot distance in Post Processor by post builder. I has run out right as desired product.
But has a Achilles every time tool change, then input value pivot distance in post processor. I am finding method to more Optimal.
