Hoe to measure Coaxiality for my part

hainhot
Hi all

Can you support me for the program to measure the Coaxiality for my part as the attachment file

I made one but it is not correct, please support to correct it

    Your alignment A2 is not correct (the origin is defined twice with different values)
    Circ4 should be a constructed circle from PNT1[1..4].
    An accurate result should use more PT1 (loop number =number of tooth)

    In addition, could you indicate on the picture who are circ1 and circ2 ?
  • Thank JEFMAN
    Your alignment A2 is not correct (the origin is defined twice with different values)
    A1 : to move from 1pcs to other pcs
    A2 : for looping : define the peak off tooth. temporary loop number =4, if program ok, I will revise to 24 = number of teeth
    Circ4 should be a constructed circle from PNT1[1..4].
    => I revised
    could you indicate on the picture who are circ1 and circ2 ?
    => already have in attachment file

    Result is same, like picture spur.png

    My mission is measure coaxiality of c1 and c2 for all pcs in picture capture.jpg => can you support

    Coaxiality or Concentricity?

    You should also try to level, rotate origin in your alignment.
  • I would try something like this, with CIR1 and CIR2 measured on the first line of 5 gears (the bottom line on the picture)

    There's also a solution with 2 arrays of values (x and y)...

    Happy week-end, all Slight smile !
