G-code G76 is a cnc cycle which is used for thread cutting on cnc machines. G76 Thread Cycle can be used for Taper Threading, Multi-start thread cutting. Number of spring cuts. This means, when done with the thread cuts, that the machine can be programmed to take a number of extra cuts at the same depth to . Threading is an integral part of almost every component which is machined, threads may be internal (ID threading) or external (OD threading).
