Fanuc G76 Threading Cycle- 2 line
G76 P020060 Q100 R0.05
G76 X30. Z-20. P1024 Q200 F2.
Explain the meaning of the parameters:
Row 1:
P: consists of 6 numbers, divided into 3 pairs:
The first pair: "02" is the final cut - repeat the last slice;
The second pair: "00" is how to exit the tool at an angle of 45 degrees at the end of the thread
Pair 3: "60" is the angle to eat the knife angle (ANGLE eat knife often used with G76 is: 80, 60, 55, 30, 29, 00 depending on the type of thread needed)
(P1 / P2 / P3 / Corresponds to 3 types of radial feeder, 1 me, 2 me.- it depends on whether the machine supports it.)
Q: depth of end cut layer - MICROMET unit
R: cutting layer thickness
Row 2:
X: thread diameter of thread.
Z: length of the thread.
P: total thickness of threaded threads to be cut in radius- micrometer unit
Q: thickness of the first layer in radius - micrometer
F: thread pitch
R: taper-threaded threaded angle, the value calculated by the formula: R = (Start Diameter - End Diameter) / 2
