The Find [Axis] buons cause a probing move similar to the Probe [Axis], Set Work Oset buons,
but will not change the work oset value. Instead, the locaon of the probed surface is displayed
in the label below the buon.
6.9.2 Rect/Circ Tab
The Rect/Circ tab contains buons that automate tasks like nding the center of a pocket, slot, or
bore, as well as nding the center of a circular or rectangular boss (see Figure 6.39). As the on-
screen instrucons suggest, rst jog the probe below the top surface of the feature to be probed.
The Find Pocket Center, Set Work Origin buon works in either a round or rectangular pocket. The
probe moves in both X and Y to nd the pocket center. The Find Center, Set Work Origin buons
perform a similar probing operaon, but in X or Y only, and are intended to be used to nd the
center of a slot.
The rectangular boss center nding roune hunts around the edge of a square or rectangular
workpiece to nd the center. To use this roune, start with the probe below the top surface of
the boss and on the le-hand side. Similarly, the circular boss center nding roune probes three
mes to nd an approximate center of curvature, then conrms the circular boss center with four
addional moves. To use this feature, start with the probe below the top surface of the boss and on
the le-hand side.
The Find A Axis Center & Set Work Origin buon is available for use with a 4th axis mounted in the
A-axis orientaon. The funcon probes a round workpiece mounted in the A-axis to nd the center
rotaon of the A-axis. Move the probe to a point approximately directly above the A-axis center of
rotaon, and click the Find A Axis Center & Set Work Origin buon.
