Yes, I forgot about the "D" for tool diameter, but yes this value would be for the X axis dimension, actually in either diameter or radius, this depends on wether you are working in diameter or radius, G7 or G8. >> Then on the next part, we will MDI back to T0101, manually jog and touch >> the face, and instead off a tool table entry, we instead go back to MDI, >> and enter a G92 Z0.000, > Why G92 and not G54 (or 55 or whatever?) > We only reference the G54-59 coordinate systems on the Mill side, on the lathe side, we solely use G92. I believe it is because we are only working in one "plane" and are only referencing one part, the G54-59 allows you to run say 5 parts in 5 different vises in one cycle, all using a different coordinate system, that way the cutting program would be identical for each part, but the code would repeat 5 times in the main program, with each of the 5 sections calling a different G5X coordinate.
