This topic have not direct relation to NX, but now I working for MAZAK e1060 postprocessor with measuring cycles, later I will show some results.
But now I have one question-problem.
My measuring part - in G54 (56, 55 not so important). For measuring motion I translate and rotate this coordinate system to target point with G68.2 and use G31 (with G43, of course) for probing. Ok, probe make few ding-ding and I can use #5061, #5062, #5063 etc. The question is: this values is coordinates for which point? Probe tip? Ruby ball center? Bottom plane of spindle? Pivot point of head? And - in WHICH COORDINATE SYSTEM. I know - not in the rotated and translated G54..
Do you have any same expirience?
Solved! Go to Solution.
The values stored in the skip read variables (#5061, #5062, etc.) after a G31 move are relative to the pivot point of B-axis head in the active coordinate system (G54, G55 etc. + shift). I am not sure how G68.2 affects these coordinates as I have not done any testing with it.
Thank you, esn! I have a same results after testing. In this case (when I measure bore or boss with B<>0) I need algorithm to calculate 3points circle radius and center. Now I can do it, tor 3 points from B-Head I can calc R and XcYcZc for center circle. Of course - I must to recalc it to unrotated BC CSYS.
Thank you in any case!!
