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).

In threading, the cycle creates all the repeated moves needed for the thread to be produced. My advice is just ignore them all and use P2. Pneumatic or hydraulic clamping systems. These extra cuts are called spring passes. Multi Repetitive Cycles do what the title suggests, they repeat moves within a process. Providing you input the insert angle A60 on a 60 degree thread form then you will get flank cutting.
