Tornos GT13 with FANUC 31i-B

Hello,

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:
M1.8x0.35
5 mm deep
Tool diam 1mm

Can anyone help me ? I never done this before.

Many thanks!

Up...........

Is this an axial thread or radial thread? Where do want to make the thread milling operation, main spindle or sub-spindle?
