CAM for Fanuc
Vertical machining centres with Fanuc 0i, 16i, 18i or 21i controls, and controls that read Fanuc programs (Haas, Syntec, GSK, KND and others in Fanuc mode).
From a post users run
What the Fanuc post writes
- % at the start and end, O1000 on the second line, comments in capitals
- G91 G28 Z0 (Z to the machine home) before every T<n> M6 and at the end
- G0 G43 Z<clearance> H<n>: the tool length comes in on a Z move
- Drilling cycles G81 / G82 / G83 / G73 with G98, rigid tapping M29 + G84, dwell G4 P in milliseconds
- Cutter compensation G41 / G42 D<n> for wear
- Every coordinate with a decimal point (Fanuc reads X10 as 0.010 mm)
Files end in .nc. Every file is read back before export and checked against the simulated toolpath.
Shaped after a Fanuc post users already run (SharpCam's Fanuc machine definition).
If O1000 is taken on your control, change the program number in a copy of the post.
Rigid tapping needs the option on the control; without it use Thread mill.
