Measuring Length was inaccurate

HVLee
Hello, I have the plastic tip (see image) and when I write the program to measure the length, it is always shorter comparing to the micrometer (use it as reference). Please see the program and let me know what i am doing wrong. I have 64 tips and place them on the fixture horizontally on the CMM. The attached program measured the first tip. Thanks.

  • Hi,

    * it should work better if you level "LIN1" instead of the "SEPNT1"

    * your norminals from BEPNT1.X and BEPNT1.Z are not 0, the hit seems not centered
    (unless the hit should not be in the center)

    * the drawing has no dimensions i can't compare the measured points and i don't know if what the measuring machine spits out is right or wrong
