.8MM Stylus checking a 1.0MM hole Clearance Clarence...

[[Je...]]

First is there a setting, utility, plan...something to direct the stylus to approach and retract from the center of a circle when scanning a circle? Because this makes perfect sense...

If not, my clearance data is at -.8MM and still off center. So negatives don't work. 

 

Thanks.

set your clearance distance to 0 and retract distance to .1

Retract distance is the distance off the wall for a cylinder, and it is based on ball center. So Retract=( Radius of the hole-Radius of the probe) should put it right down the middle, if the hole is at nominal position (A system cant adjust to a position that it doesn't know yet, so it has to run to the nominal). As Dustin indicated, 0.1 for retract in this case

The .1mm would place your stylus in the center from Nominal, not from actual, but it should work out.

As for the Clearance Distance, use the default then set the speed to 10. The stylus will move into the hole very slowly.

Retract distance = (hole dia - probe dia) / 2 

Clearance distance on a circle or cylinder is parallel to the axis.
