Hi, I see what you are after. I wish I had that function as well, there are a few times I would have made good use of that.
On the same topic, if you have a machine which has a vise (for example) that never moves, you can output the offsets directly in the program.
For 3 axis machines, I think the math is from home, for 5-axis the math includes home position and center of rotation. All this is done in the post, and it outputs G10 lines at the beginning of the program (assuming Fanuc controller). There is such a function for all controllers I assume. For example, at the beginning of the program, the post outputs the following line:
G10L20P10X-13.6003Y-19.6388Z-18.4076A0.C0.
This established the work offset G54.1P10 (you can make it work for G54 of course, just need to look this up in the Fanuc manual).
For us, that means that any operation that is done on the raw material can just run, nothing to pickup (of course the position on the table has to be the same as in the software, so again, this is for fixtures that never move). Any operation that is done on previously machined operations, we add a probe just to make the position super exact. This is not useful for most people, but we use a lot of fixtures that are always on the same spot (think the Fifth-Axis vises etc).
I just thought I'd mention this in case it could apply to you, but I still would like to have the function that you described for sure!
