I have an abb with track and lathe axis. I'm trying to follow a crankshaft journal with a thermal spray gun and maintain the same standoff as the journal turns. I have a servo on the lathe that is an axis or I/O. I'm fairly new at this. Looking for a little help.thanks for your time.

Unless it is a coordinated external axis, your chances are not too good. Check out this system at the beginning of the video, it does exactly what you are describing.

The external axis is coordinated.

OK, very well. Teach the primary points that you need and then you could do something like offset eact go round of the shift by the step distance you need until you get to the end of the lobe. Make a jump to the next lobe and repeat. You could use either the track position or the X or Y values of the taught points. The latter could be done by using the OffSet function.

Ok. I kind of understand. I mainly work with a fanuc but it doesn't have the axis. So I would input the moves it takes for one revolution and have a register counter that adds offset after each one. Is that ballpark
-
Yeah, pretty much. I might use a FOR NEXT loop or maybe even a WHILE DO. ABB has a lot of possibilities.

I appreciate your time and input by the way. Thank you.
