G76 THREADING CYCLE
N_ G76 X_ Z_ D_ K_ A_ F_
The G76 command automatically performs all cutting operations required to achieve a thread. From the programmed variables the cycle will calculate the toolpaths, based on the desired thread pitch, depth, and tool angle. X designates the minor diameter of thread. Z specifies the end of the thread. D designates the depth of the first pass. K specifies the depth of the thread. F specifies the desired pitch of the thread. A is tool angle.
