I'd like to machine a flat area on OD of a cylinder using G101 on Okuma lathe.
I don't quite understand how G101 work???

It's great help if someone explain it and give me an example.

Thank you

what is the lathe? control? IGF? Y axis?
You can make a simple part with IGF and examine generated GM code.
Generally saying, C axis must be engaged (not clamped). it's M110, M109 - I guess ... and so on ...

G101 is part of an optional suite used with Contour Generation, but if your control has this feature, straight or arc paths can be achieved by simultaneous two axis (C and X) or three axis (C, X and Z) interpolation.

If you wanted to cut a straight path on the end of the workpiece, a program snippet as follows would work.

M110
M146 M15
G00 X100.0 C300.0 SB = 150
G94 Z10.0 M13
Z-5.0
G101 X100.0 C60.0 F40

The X100.0 in the “G101 X100.0 C60.0 F40” can be omitted of course.
