G75 Grooving Cycle

G75 is a CNC code and used to grooving for CNC lathe machines.

G75 grooving cycle also a very simple cycle, designed to break chips during a rough cut along the X axis used mainly for a grooving operation. The G75 cycle is identical to G74 cycle, except the X axis is replaced with the Z axis.
