I am having trouble programming a job that has 16 raised squares. So I need to mill around each square. I thought through G code, I could center over the first one, then call out G92 X0Y0 Then program the actual dimensions from the center. Then move over the appropriate and G92 that location and start again. problem is, the tool offset does not seem to agree with the G92. Here is the program. just copied the first row so that you can see what is going on. Any advice would be appreciated.

Thanks Mike

QUOTEmaybe this could help

Seems the active work offset g54 maybe affecting the g92 command. Would it not be easier to program you profile in incremental g91 and use multiple work offsets / offset shift?
Hope this helps

You might need to state the z value on the g92 line also.
What control?

I drew up some .125 squares, .0625 above the substrate, camed it up in sprutcam, using a .100 endmill, flatland finishing op, it simulates OK.Attachment 279724Attachment 279726

the pics are the squares and part of the code from the post processor.

Flatland finishing is what I used here.

Hand coding I cant help with as I havent learned how to do it other than some simple MDI commands.

How far apart are the bosses? I would probably program that part as a pocket with 16 islands (bosses) and use the biggest cutter that would fit, then I wouldn't have to be concerned with a move and a G92.

If you'd like, you could send me a cad file of your drawing in a parasolid .x_t file and I could whip something up pretty quick.

Sent the file to [email protected].

That part should only take 15 to 20 minutes to produce a Gcode file.

Thanks Steve. I sent you the file.

Thanks Steve. I sent you the file.

Good Morning Mike, check your email. I posted the program the way I would run it. It's programmed to run on a Fanuc 6 control. Run time is aproximately 13 minutes, but my cam software take into consideration rapid moves ot tool change times.

I don't have the ATC on my machine. If you have one on your machine you might want to edit what I sent you to accommodate the ATC.

You can reach me at 714-420-2453. If I don't answer, leave a message and I'll call you mack
