N_ G71_ P_ Q_ U_ W_ D_ F_
The G71 command automatically generates roughing passes to turn a workpiece to a specified profile, leaving an allowance for finishing. It reads a program segment specified by the P and Q letter addresses and determines the number of passes, the depth of cut for each pass, and the number of repeat passes for the cycle.
