We just bought a new Swiss lathe and I'm responsible of programming it by hand and the last operation that I have to do is a internal M1.8x0.35 thread using a 1 mm diameter 2 flute thread mill.I need to program from the bottom up using G2 or G3 or maybe another G code using syntax, with C axis and Z movement
Thread details:
5 mm deep
Tool diam 1mm

Can anyone help me ? I never done this before.

Many thanks!
