I don't know what anyone else does, but I set the Z offset of tool 1 to zero, and then either face off the part or touch it off with paper. Without moving Z, I set either the work shift or work coordinate system to Z0 at that location.
Then, I touch off every other tool with paper to the faced surface, and input the coordinates relative to the work offset.
That way, when you swap work offsets, change parts, or whatever, all your tools are still set up and ready to run. All you need to do is locate tool 1 (which ALWAYS stays at Z0) and set a new work coordinate system, or move the work shift. Bam, ready to go. |
