G52 Zero Offset

[Todd Wertz]

Hi all! I was about to repeat the same part 42 times on one table. I use a G52 to accomplish this (e.g. G52 Y-2 will offset a whole sub program by –2” on Y). I use this offset so I don’t have to regen the whole sub program and thus I eliminate a lot of code. Also, I don’t have to manually enter the offsets into my controller for a G54. Can Mastercam create a executable to run sub programs and offset the coordinate zero to move the programs? If I can’t find a way to do it in Mastercam then I’ll need to do the offsets 42 times myself.

Will Toolpath-Transform work?

I'll give it a shot, but what I often get is just the same operation posted, in full, over and over.

Todd,

 

I don't usually use Toolpath-Transform, but I think you're right on that one. Maybe others have ideas.

Todd,

 

If you look in MC help under subprogram it spells it out fairly well. The bad part is that you have to chain all the geometry and it must be identical. "chain window might work" and check the subprogram box in transform toolpath. Once you've done it a few times it's not too bad.

 

Good luck

Contour "last" selects that previous selected chain so you only actually have to "select" it one time.

Works with other paths besides contour as well.

saves alot of time.

I don't think my post is set up for sub progs. I'll need to correct that first. Thanks for all your help!!!

G52's work great don't they. I used to use them all the time when I wrote my own stuff on the floor. Quick and easy way to adjust things. Some of the guys didn't like it. I think they just didn't understand it. Offsetting an offset, confused them.
