Coordinates Shift when Rotated to A90B90????

InXperienced@Best
Hi everyone,
Writing a program today that requires profile measurements on each side of the part. All is well up until I go to rotate the tip to A90B90 (Manual Rotate, Old School TTP machine).
Program runs through the DCC Alignment and runs through the move points I've entered on the left side of the part in order to rotate from A0B0 and once I rotate to the desired A90B90 to take the scan for profile, the coordinates are shifting, and the screen is showing that the probe is much farther to the right (X Axis) that where it physically is? Can anyone explain to me what I am doing wrong please?

Tip is physically at -5.0078 in X, 1.5035 in Y and .7474 in Z
Once Tip is rotated it shows it to be +1.8452 in X, 4.0376 in Y and 2.6554 in Z


Any advice is greatly appreciated, Thank You!

  • Also you're saying 'Yes - sphere has moved for each tip angle' (I can see this as in each image you've posted you can see the location of your calibration sphere 'new sphere'

    When you say 'Yes - sphere has moved' you are using that tip with it's current offsets to define the reference sphere lcation.

    When you say 'No' you are creating tip offsets relative to the tip which was used to define the reference sphere.


    First reset all your tips

    Calibrate A0B0 and say 'Yes - sphere has moved', take the manual hit and let it calibrate.

    Then for the remaining tips, say 'No - sphere has not moved' and all your tips will then relate correctly to each other.
