Hi all

I've been asked to help out with a vintage Tosh BMC 6C. It has 4 axes and the user wants to start programming the B axis for 3 + 1 milling. I'm looking for a way to shift the CSYS when the part is rotated. In what's left of the
manual I found G11 - coordinate system translation and G10 - cancel G11. As near as I can figure, it works like G68 (Fanuc, Mazak) and G7 (Heidenhain). The problem is that I can't find a single programming example to help with the syntax. I'm not learning much from MDI at the machine and web searches have turned up nothing.

Does anyone know the procedure for using this function or any other way to get there on the old Tosh?

Thanks much,
George
