[ZE...] Posted March 29, 2018 Share Posted March 29, 2018 Probing a point inside a .050" slot. My retract & approach are both setat .001, and the stylus still hits the slot wall?

[ZE...] Posted March 29, 2018 Author Share Posted March 29, 2018 Hi Clarke, I think you want to increase the retract distance above .001? If you're talking about what I think, the retract is calculated off the probe center, so if it's 1mm, you would want at least .015 to at least barely clear the slot wall.

[ZE...] Posted March 29, 2018 Author Share Posted March 29, 2018 Er i mean .020, but close enough... Dave Mecozzi | 03-28-2018 09:50 PM | Link to comment https://qualityforum.zeiss.com/topic/21124-approachretract/#findComment-120456 Share on other sites More sharing options...

[ZE...] Posted March 29, 2018 Author Share Posted March 29, 2018 Here's what I teach in my classes for narrow slots. Edit clearance distance to .000 and then then take the slot width minus the probe diameter then divide by 2. Make the answer your retract distance. That will bring your probe to the exact center of the slot.

[ZE...] Posted April 3, 2018 Author Share Posted April 3, 2018 I do the slot width minus the probe diameter then divide by 2 thing all the time. For some odd reason I had a brain fart.
