ISO 1101 Position tolerance

Sekarkm
Dear Quindos experts,

I am learning quindos 2020.2 with basic training given by the cmm supplier and installer. I am having difficulties to evaluate the ISO position tolerance for inner and outer cylinder (hole and pin). I have measured the elements as cylinder and as a basic circle. The position tolerance for the circle I used the command POSITNXY with circle tolerance zone and got the result as expected with X_correction and Y_correction ActualValue. I can understand the value is the difference from Act vs measured. If the measured value is plus(more) it shows with X correction -0.0000 and oppsite for less.


Could you please explain how to evaluate the position tolerance for the measured cylinders using the position (POSITN) command. I mean all the correct inputs for this command to get the position tolerance as per DRF.

What is the X and Y correction values and how to understand?

I just enclosed the rough sketch and the snip from the results.

Thank you for your kind help.

Regards,

  • Try :

    POSITNXY (NAM=CYL40PTN, OBJ=CYL40, TYP=CYL, DIX=190.2, DIY=136.5, MIN=0, MAX=35)
    ​

    Hi,

    I am sorry. Thank you for your kind help and support. As you said, I tried POSITNXY command for the circles I have measured at Z2.0 and Z33.0 and the position tolerance were correct and confirmed with manual calculated position. So, POSITNXY correct for the circle with circular tolerance zone.

    I just wanted to evaluate position tolerance for the CYLINDER 35mm length. ( I mean the cylinder axis sitting with in the cylindrical tolerance zone).

    If you could please, try and put the screen shot of the POSITN with the correct input parameters for the CYLINDER 35mm length.

    Thank you.
