This probe cycle is used to locate the center of two parallel faces in a rectangular protrusion (web) whose walls are perpendicular to the XY plane. The center of the web is given by the GOTO point issued immediately after the verify command. The motions governed by this cycle also use parameters from the CL command, PROBE/RANGE, TO, a, PAST, b. The value of u201cau201d from the PROBE/RANGE command is used to determine the approach distance as the probe moves toward the face. The motions expected for this cycle are: rapid from the current position to the clearance height above the target point. Feed in the clearance plane to the approach distance from the minimum X face. Feed down in Z to the depth below the target point, feed in to touch the face. Feed back to the approach point, feed up to the clearance height and repeat for the other face. End the cycle at the clearance height above the target point.

The PROBE/RANGE command must be programmed prior to using this command.

The width of the web.

The angle at which the width is measured. A value of 0 indicates that the width is measured along the X axis. A value of 90 indicates the width is measured along the Y axis.

An optional couplet. It is used to indicate the height above the Z value of the target point to change from rapid to feed rate. If not programmed, a height of zero is used.

An optional couplet. It is used to indicate the depth below the target point at which the touches will take place. If not programmed, a depth of zero is assumed.

Indicates the feed units and velocity to be used during the probing motions. This couplet is optional. If not programmed, the most recent feed velocity is to be used.

These parameters are used to indicate how to use the results of the probing operation on the machine. They do not affect the subsequent motion.
