Hello all!

I am slightly disturbed with the motion we are getting with our Mazak E1060 and the C axis with G43.4. The B axis works as one would expect and keeps the tool tip over in sync with the current position when issued a angle change. C axis doesn't do this. For instance if you give the C axis a 90 degree move, the X and Y axis move in these large looping moves to get to the end point. Guys from Vericut can't replicate the movement and Mazak can't explain it mathematically although they insist the motion is correct. Anyone else have this issue with a E1060?
I have been around many 5 axis machines and set them up and have never seen a machine act like this.

You have other commands running as well?

there's a parameter that controls how the machine views motion in G43.4.... you can alter between Type I and Type II depending on settings. This may be causing your "unexpected" move. Then again, it's 5-axis tool tip control so a C move in the code with no update for new XY would cause the tip to track the rotation while staying engaged at that point....
