NOTE When a probe is selected from the Probe menu of the Measure toolbar it is set as the current probe.
Configuring Probe Path Data The probe path data settings define the default probe touch probe behavior for CNC programs. All probes used in programs initially use the default probe path data settings. These settings can be edited in program steps when the default probe behavior needs to be modified to meet the needs of a specific application. Editing probe path data steps is discussed in Section 11: Programming.
Probe path data are configured in the Probe Path Settings screen. To configure probe path data: 1 Press the Probe Path Settings screen button. The Probe Path default configuration will be displayed. M3 System menu > Settings > Probe path
Probe path data configuration fields include: •
Approach distance: Distance from the anticipated target surface where probing speed is initiated in the current unit of measure. The approach path is calculated by the system to be approximately orthogonal to the target surface. • Search distance: Distance added to the approach distance when surface contact is not made at the anticipated location. The measurement fails if contact is not made within the search distance. • Clearance distance: There are two clearance distances of the same value. One clearance is toward the target and included after the non-probing speed to the target and before the approach distance. The second is away from the target and included after the retract distance and before the next non-probing speed begins to the next target. The clearance moves are intended to locate the probe so that the to-target and from-target moves will be unobstructed. The clearance directions are determined by the system based on the target feature surface being probed and generally moves along the probe tip axis • Retract distance: Distance that the probe moves immediately after contact is made with the target surface in the current unit of measure. The retract path retraces the approach path for a small distance at higher speed. Retract speed: The speed in the retract region expressed in mm per second • Probing speed: The speed in the approach and search regions expressed in mm per second • Non-probing speed: The maximum probe speed between features CAUTIONS When preparing programs for parts that include complex surface variations in 3D space, care must be taken to avoid probe collisions. The clearance distance might not be adequate to eliminate collisions and might need to be replaced or supplemented with manually programmed Goto (safe) moves. Goto moves are discussed in Section 11: Programming. The default Non-probing speed might be too high for first executions of complex part programs. Debugging complex programs at lower Non-probing speeds reduces the possibility of probe damage. The Non-probing speed can easily be changed in program steps during the program debugging process.
