Re-zero between toolpath groups

[youyou43]

Hi,

I have a part that needs to be machined from three sides (front, bottom and back). So I have a MasterCAM program that has three toolpath groups. Each group contains the toolpaths for each side. When I finish one side, I need to flip my stock and re-zero it on my CNC mill. I looked at my program and I didn't see any codes that would tell my CNC mill to pause and let me re-zero my stock. Should I just create one set of g codes for each group? Can any one point me to the right direction? Thanks!

Regards,

Steven

Personally, I would approach this as 3 separate programs. If you want a forced machine stop in a single program, you can use Toolpath > Manual Entry > Insert as code and type in M00 (SET WORK ZERO).

Thanks for your reply, txcncman! I used to do the way you suggested. But it's a big headache once the part gets very complex. There are always something missing if I don't look carefully. I think what I am gonna do is to have one single program and generate one set of codes for each toolpath group. In my case, one single program and three sets of codes. I can see a complete finish part in one program by doing this. What do you think?

You can still view the entire part even when outputting as 3 separate programs.

Here is an example for you.

Notice in txcncmans file that when you expand out the paths with different offsets they are marked as different NC names and different program numbers so when he selects all and posts it will prompt him for three different gcode files. The only this I would change would of but each different group of ops in there own tool path group easier to organize and review.

Now are you using one vise or mutable vise with different setups were you can flip the part thru and every cycle remove a finished part?

Your file is very helpful! Now I see how this thing works! Thanks for all your help!

I agree with you. I would group my operations into different toolpath group too.

I agree. I modified this file from another set to run all ops on different vises. The tools had been grouped by Tool Number, not Work Offset Number. You can't group by Tool Number across Tool Path Groups, they all have to be in the same one.
