SECTION FOUR - PREPARATORY FUNCTIONS (G CODES)
Programming with Cutter Compensation

should be done off the part per the figure below. The movement made prior to cutting should be
at least the distance of the cutter diameter being used.

No-movement (G65)
The G65 is used for starting and ending cutter compensation. The G65 code placed on a line with
coordinates will cause these coordinates to be used for cutter compensation points but skipped
during machine movement.
G65 X___ Y___ Z___ The machine will not move to the XYZ coordinates.
Note: G65 can use polar move as well as Cartesian coordinates.
