Backfacing Operations

[Kampfzentrum]

Hey guys,

Got a question about backfacing operations. Basically I got a tool that rapids in to M00 (requires a head to be placed on it), machines - backwards - the spotface to depth, and will need to rapid down (again M00 for tool removal), and rapids out.

Maybe a canned cycle? Definitely open to suggestions.

Thanks in advance.

What about manual entry and a sub program?

Or Custom Drill Cycle......

I have a V9 topic out there where I showed how to do this around 2005. It wouldn't be hard to make the adjustments needed to do it for 2019.

Be careful with your m00 , I had to click force tool change in the path after the manual entry moo that I used the other day (mc2018), or the spindle would not start for the next operation!!!   the coolant stayed off too. 

 

It worked OK on a 2d path, but not the finish contour that I used next. the post missed the m 3s1234.

I think what I'm going to do is create a custom cycle by just authoring the G&M code and inserting it as a subroutine. That way the program will pull up to the location, then execute the subroutine. It's not doing anything crazy, just a few feed moves, a rapid, dwell, a stop, etc. I'll have to look into the spindle stopping after the M00, that could be an issue and most likely will be.

I'll be honest, I don't even know where to post that. I know that most guys on here have a in-depth knowledge of Mastercam, but I never got that kind of training or have messed around with it. If I was more knowledgeable, I'm sure I could do something with this, but at this point I'm not there.

Thanks though.

Then I suggest you get a hold of your dealer and let them help you if you want to use a drilling cycle.

You can use Manual Entry to do this also.
