Follow These Steps to Program Thread Cutting on a CNC Lathe!

In the 6th video in this series, Marc, aka @GCodeTutor continues the series on manually programming a complete part on a CNC lathe using G-Code.
This time, it's about screw threads. There are a few ways to approach thread cutting on a CNC lathe by using G32, G92, or the more common G76.
Marc walks us through, line by line on how to write the G-Code for this sequence.
When programming the two-line version of the G76 cycle, the P and Q values aren't calling a subroutine this time, but instead giving the machine information about the thread we want it to cut:
G76 P(1)(2)(3), Q, R;
G76 X, Z, P, Q, F;
First line:
P(1) = Spring passes
P(2) = Chamfer
P(3) = Angle of thread
Q = Minimum cut
R = Finish allowance
Second line:
X = Minor (core) dia of thread
Z = Endpoint of thread
P = Depth of thread
Q = Depth of first cut
F = Pitch of thread

Just found it sorry - Well explained thankyou, have you done a metric video as well?

Great thanks
