lathe comp

[Mark C]

Hello all,

I'm fairly new to MC lathe (v9 sp1) and have a question. Sometimes when boring, and using comp I get a G42 instead of a G41. One of the setup guys pointed this out to me, so I went back and checked some prev programs and some are right and some (fortunately the minority) are wrong.

What might I be doing wrong. I tried posting with the MPFan post right off the install disc, so it's something I'm doing.

Thanks in advance

I don't use MC Lathe, but in mill, if you reverse a chain after the toolpath has been generated, it will switch your comp direction. Is this a possibility?

The first step is to re-check the direction of your chains. Also make sure that you are looking at the ID path and not the OD path.

If you are using "reverse wear" for comp,this may post it different too.

Thank you for your responses,

Chains haven't been reversed, and are in correct direction with tool on correct side. I'm using comp in control.

Funny thing is, I came in this morning and regenned it and posted it and it came out right. The ops weren't "dirty".

When it does it it's putting out the right x & z, just a G42 instead of G41
