SECTION FOUR - PREPARATORY FUNCTIONS (G CODES)

G65 will allow the programmer to turn cutter compensation on and get the tool to drop or retract

at a specific point without doing any extra moves. Generally the no-move point would be chosen

to be a point on the part that directly precedes the tool down point. On a tool retract, the no-move

point would be a point on the part directly after the tool up point. The no-move point does not

have to lie on the part, but points on the part generally work the best. The following sets of

figures under “Starting and Ending Cutter Compensation” show various tool start and retract

positions given different no-move points, which are indicated by the dotted line (---). Point 2 is

the desired tool start or retract point. Point 1 is the no-move point in the cutter compensation on

(pierce) case, and Point 3 is the no-move point in the cutter compensation off (retract) case. If

cutter compensation is turned on or off using the following format, the tool up and down position

can be easily predicted.
