SECTION TWO - FRONT PANEL OPERATION
Procedure for Setting a Work Offset
A work offset shifts the X and Y axis zero positions to a desired place (edge of the part). Thus a
part can be programmed from its part zero. To find and set a work offset, refer to the example.
Using a ½" diameter edge finder in the X axis, handwheel or jog to the edge of the part and
depress F8 (G54-X). Establish whether the edge finder is positive or negative from the desired
zero. Enter -.25 for the X position. The current position will read X -.25. Repeat this procedure
for the Y axis.
To check a work offset zero, select F5 (MDI), type G0 (rapid move) X0 Y0 (X and Y position to
0). Press Enter, then Cycle Start. Machine will position to the current work offset.
Caution: Machine will move in rapid mode. The tool should be above all parts, vises,
etc.
For more information on floating zero, see page 294, Section 4.
