Good afternoon everyone, I am currently trying to measure features on a tubed part. I have a 5 way that i am using but only using two tips. I thought my knuckle was working for a little bit and I use my master to calibrate both directions and then switch to my probe build and calibrate all tip 1 angles first then change to Y+ direction for the knuckle calibration and i thought the StdDev looked ok but everytime i try to measure the features at the bottom, it is giving me Very High Results. I measured the same part a month ago and all the features were in spec underneath and now i am measuring the same part and all the features say they are way out. I am totally confused by this and I've exhausted all options. Can someone please help? Attached are images of my probe build and setup.
Ninja, Yes I calibrate the Knuckle probe with the Y+ Direction of the sphere. The sphere has been in one place so I don't have to use he Master to locate it.
I typically Calibrate my probes every program I run. I can show you my Calibrations Stats for the Knuckle. I use scanning probes so I do 24 hits on 4 levels.
