Probe hitting style and show plane profile with hit points X Y Z variation

RobOntario
Hello All

I was moved to another plant with v2019.1 and got some confusion, I really appreciate any help for those issues:
1. Our old v2015.1 when works on calibration, the probe hits the sphere very quick and moves to the next hit. The current machine hits the sphere and stays for a while before retreat. I did read the manual before, I remembered there should be setting to choice those different hitting modes... but can not find it now.

2. When we measure a plane, if the profile is out of SPEC, and shows red, for example 0.059 , the SPEC is 0.075. I believe this is because PC-dmis calculate profile using Lease square method, but the profile is calculated by MAX MIN points deviation. Can we show those points from the plane on the results ( I can pickup points and form a plane, and show both of them, but can measure the plane and show the points by X, Y Z)

Thank you

  • In your example of profile, could you post a screen shot of the result ?
    If the spec is 0.075 on a profile, it should be ±0.0375, so 0.059 is OOT ?
    If it's a flatness, then the tol is +0 + 0.075 so .0.059 is ok.
    The profile uses the T value, and the plane must be constructed with minsep.
    Then
    ASSIGN/TVAL=DOT(PL1.HIT[1..PL1.NUMHITS].XYZ-PL1.XYZ,PL1.IJK)
    ASSIGN/MAX_VAL=MAXINDICES(TVAL)
    ASSIGN/MAX_POINT=PL1.HIT[1].XYZ
    ASSIGN/MIN_POINT=PL1.HIT[NUMHITS].XYZ
