okuma lathe cutter comp

[Mark VIII]

We have a new post for programming Okuma lathes. A problem I am having is for finish cuts it applies cutter comp during a G00 move. That causes the machine to alarm out. I must then edit the NC file to apply the cutter comp at the first G01 move. Is there a way to get the post to do this? I see in canned cycles you have a bit of cutter comp control, but not so much in contour ops.

So you say you have a "new" post...

If this was a purchased post, I would kick it right back to the post writer...

It seems to be rather generic. I would prefer to fix it myself. My experience with the MC vendors is that they have little interest in spending the time to fix posts correctly. We usually  have to go around and around and around to get it done.

I figured it out.

Care to share what the fix was in case any of us run into it?

Yeah, sure. What Okuma was demanding was that the G41/42 line needed both an X and a Z value. It did not necessarily need to be a G1 output. For some reason the X and Z outputs were on separate lines. I moved the xout to the same line as the zout in the tool change setup and everything worked well.
