Force C-axis output for radial drilling in mill/turn Okuma lathe

[cyltech]

We have an Okuma LB-15IIM mill/turn lathe that we have a working post-processor for, modified from an older version of the stock Autodesk post for Okuma LB-3000

I have a problem with that post, since the OSP-7000L control requires G181/G183 radial drilling cycles (drilling on the side of workpieces) to have C-axis value outputs in the same line as G181/G183 cycle calls.

Live-tool drilling radially (on the face of workpieces) does output C-axis values normally, but I cannot figure out where the post-processor is getting those values and apply a similar code to output C-values on side drilling.

Even the current version of the Okuma LB-3000 post only outputs C-values on axial and not radial drilling, clearly reproducible through the visual studio code post-processor extension mill-turn demo programs.

Can anyone help me out with the default LB-3000 post to get the C-axis values to output?

Take a look at the getCommonCycle function inside of this post:

I've put a lot of work into this to make it "okuma friendly". Might be a good starting point for 7000 control post

Thanks, I copied the getCommonCycle from your latest post in that thread and it worked.

The only things I had to change were:

1) Remove the "conditional(useM136, mFormat.format(136))"

2) Change plane from 19 to 18, since the LB15-IIM doesn't have plane 19 and I've changed other post designations to reflect that

Thanks a bunch!
