This is the diameter of the probe tip. The accuracy of probe measurements is directly affected by the accuracy of the probe tip diameter.
RAPID (velocity)
Axis movements not associated with searching are done at the speed defined in machine units per minute.
SEARCH (velocity)
Axis movements associated with rough position searching are done at this speed defined in machine units per minute. . The search speed should be slow enough to give an acceptable initial accuracy, but fast enough to not waste time waiting for movement. Recommendation: 200-500 mm/min. Once initial contact has been made and the probe is retracted, it will wait for 0.5 seconds before performing the search again at the lower probe velocity.
PROBE (velocity)
Axis movements associated with fine position probing are done at this speed defined in machine units per minute. This lower speed ensures the machine can stop movement as quickly as possible on contact with the workpiece.
XY (clearance)
The distance that the probe will move away from an edge or corner before performing a search. It should be large enough to ensure that the probe will not contact the workpiece or any other fixtures before moving down. It should be small enough to avoid excessive waiting for movement while searching.
The distance that the probe will move down before performing a search. If measuring an inside hole, the probe could be manually jogged to the starting Z height and then set Z CLEARANCE to 0.
