Simple ( i hope) cutter comp question
I have a simple cutter comp question. using a g41, why does my machine move in both the X and Y even though there is no X on the comp line? Below is the program that I am running. I have modified this from a Fanuc program. It runs fine except for that. It doesn really hurt anything, but I would rather it didn't do it. It only moves on the Y when it comes off cutter comp.
Thanks Mike

Re: Simple ( i hope) cutter comp question
Gerry got it.
Cut comp is moving from the previous X Y location.
That's why you should have a 'lead-in', 'lead-out' move for cut comp.
Re: Simple ( i hope) cutter comp question
I do have a lead in and out. Still don't understand why it moves on 2 axises. Never worked that way on my Fanuc and Yasnac control. So if I ma milling a pices of stock to length, there is no way to get it to just make a comp move on only the X axis?

Re: Simple ( i hope) cutter comp question
No, the lead in move will always move on 2 axis.
The Lead-In move in your code is the one with the G41 in it.
