we have an Okuma lathe here with an OSP7000L controller. We normally longhand everything or use cam software. Trying to figure out canned cycles here. I have the format just how it says and even how i have seen other people here post it. The problem is, on the OD cycle im trying to leave .006 on the faces (W value, W.006) the cycle runs however, it is taking an additional .006 on the faces instead of leaving it!!! What the hell?? These Okumas are so different in some ways from Fanuc it drives me crazy. It has to be something stupid. Maybe a parameter? I dont know. Not using comp either. Thanks for any help.

When using a turning cycle on bar stock, the OSP "usually" would like to see it something like this:

Example = 4." bar stock, 2.5" long. Turning a 2." hub.

The way I would generally do mine for a simple single depth LAP. I have never done it the way you showed. Does it pretty much work the same way? I have much more FANUC experience than OSP.

It works quite well.
 
Here is a snippet of a boring lap routine. (this is for OPS2000)

The rough tool is set conventionally, with Z0 at the front.
The "T0101" on cutting conditions line calls up the tool and offset.
If i were using cutter comp, it would read "T010101"
Correct, but if a different tool is establishing Z0 and his shoulders are too deep, it may be a slight Z0 offset adjustment on the facing tool to give correct shoulder depths.
He didn't say whether he checked the should depth after roughing but before finishing.
 
Are you measuring the depths from the front of the part(Z0)? I don't see a facing pass in here anywhere done at Z0 to establish anything. I think booze may be on the right track where your facing tool and this tool may just not be taught correctly to one another. Also if you run everything you posted, there won't be any material left behind for finishing after the G87 runs.

g87 is the finish pass g85 is the rough
