Manin program will be same , G76 Threading Cycle, Multiple Pass (Group 00) * A - Tool nose angle (value: 0 to 120 degrees) Do not use a decimal point D - First pass cutting depth F(E) - Feed rate, the lead of the thread * I - Thread taper amount, radius measure K - Thread height, defines thread depth, radius measure * P - Single Edge Cutting (load constant) * Q - Thread Start Angle (Do not use a decimal point) The G78 threading cycle is similar to the G76 threading cycle, with the same thread calculations and parameters, but with a different command placement. Since the feed rate in inches per rev does not change, it seems When using a G32 the to do the higbee the feather edge is removed but it makes a long ramp out of the first thread instead of a blunt start.
