Q:We are making Three-headed Worm by G76 on a CNC lathe with GSK 980 TDa controller, but the Finish is not good, can we use two tools, one rough tool and one finishing tool, will it conflict with each other? Which G codes can we use two tools?

A: You could use two tools in this case, but the most important thing is to raise the spindle speed of your lathe machine.
