I could use some help setting up my cnc lathe. I've worked with Machining centers for a long time, but am new to lathes. What I am having trouble with is - how do you set x,z zero for the work offset (i.e. G54) ? I have heard some comments about using a reference tool, but do not understand it completely. Just about everytime I have programmed a mill, I set the x,y zero to the part zero then touch off all the tools in Z and ready to go. Lathes aren't the same, obviously. The machine we have is a Daewoo Puma 6-HS with the Fanuc 10T. Any help and insight will be appreciated.
