Calibration Start and End Angles for disk probes

Irongrid
Again I am new for disk probes is there a preferred angle range being they are not spherical it puzzles me.

  • hello

    you can use this calculation to figure out ur start-end angle.


    example:

    18mm disc dia x 2mm thick
    Calibrate using only 70% of the disk thickness (out of square comp.)

    2mm x .70 = 1.4mm

    half of 70% thickness
    1.4mm / 2 = .7mm
    Half probe dia.
    18mm/2=9mm
    Calculate the angle from horizontal center line to half disk thickness

    SineA= .7/9
    A=4.4º

    Start angle -4.4º
    End angle 4.4º
