G72 ROUGH FACING CYCLE
N_ G72
The G72 command automatically faces off a part to a predefined profile, with preset offsets and feedrates 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.
