SECTION FOUR - PREPARATORY FUNCTIONS (G CODES)

Sample Program for Enter-Exit Cutter Compensation

G0 X-5 Y1 part load/unload point

G41 D1 F10 cutter comp. on offset #1

G65 X0 Y1 no move compensation point

X0 Y0

G1 Z-1 tool down

G65 X1 Y0 cutter comp. off no move exit point

G40 G0 Z0 tool up

Note that the tool enters and exits the part tangent to both walls because of the G65 lines.

Notes on Cutter Compensation

Note 1: Turning compensation on can be done both in a block without axis movement or

in a block containing axis movement.

Note 2: There is no restriction on how many successive blocks can have no axis

information.

Note 3: There is no restriction on how lines enter and leave arcs. They can have any

angle of intersection as long as an intersection exists.

Note 4: Given the correct centers and radii for two intersecting circles, the system

automatically checks and corrects the programmed point of intersection, i.e.
