? make cycle 7.0 work when chose a new origin about heidenhain 5-axies

[davidtan20]

Hi guys,

I had a problem when I made my own UG nx7.5 post of DMU eVo linear (5 axis with B & C) with heidenhain control, the result is ok if no rotation involved, but when I have spatial rotation, the cycle 7.0 values keep same but I tried it on CNC turns out not right,some people say that we need put fixture offset(cycle 7.0) right after rotation not before, I tried that too but nothing changed. I knew that as long as keep one origin for whole program everything seems alright, but there is a way that you chose the convenient new origin.

Is there anyone can help me out here ? thank you

I do not know if it matters, I tend to have the cycle 7 just before the cycle 19(plane) and after the tool change. The fixture offset should be in the B0 C0 axis system. If repositioning the cycle 7 does not work find out if the parameters required for the machine model on the controller are set. Some evo's do not transform the cs properly. A work around could be to do the cs transformation in the postprocessor.

I am going to talk a DMG application guy see if I can get help.

I have tried only running cycle 7 without cancellation, from machine readout the part origin really changed, so I am guessing "Some evo's do not transform the cs properly " is right.

I have tried make a new custom-command TCL file from csys_rotation for the "work around" seems to me no luck

thank you very much jelmerra
