  • Dimensioning Auto Round Slots

    I have never used the auto round slot feature...never had the need. I programmed up a piece using it today...when I dimension the slot I seemingly can only get the overall length, do I need to use assignments to get the distance between the 2 radii of the slot?? Like below??

    ASSIGN/V1 = SLT1.LENGTH-SLT1.DIAM
    ASSIGN/V2 = SLT2.LENGTH-SLT2.DIAM
    F1 =GENERIC/CIRCLE,DEPENDENT,RECT,OUT,$
    NOM/XYZ,0,0,0,$
    MEAS/XYZ,0,0,0,$
    NOM/IJK,0,-1,0,$
    MEAS/IJK,0,-1,0,$
    DIAMETER/1.25,V1
    F2 =GENERIC/CIRCLE,DEPENDENT,RECT,OUT,$
    NOM/XYZ,0,0,0,$
    MEAS/XYZ,0,0,0,$
    NOM/IJK,0,-1,0,$
    MEAS/IJK,0,-1,0,$
    DIAMETER/2.75,V2
    DIM LOC4= LOCATION OF CIRCLE F1 UNITS=IN ,$
    GRAPH=OFF TEXT=OFF MULT=10.00 OUTPUT=BOTH
    AX MEAS NOMINAL +TOL -TOL MAX MIN DEV
    D 1.2511 1.2500 0.0050 0.0050 0.0000 0.0000 0.0011 -----#---
    END OF DIMENSION LOC4

    The length of the slot, LF, will give you tangent to tangent. If you want center to center, you will have to create a circle on each end and dimension the distance between them.

    I would suggest that you report the tangent to tangent, LF, though as it is a more useful number.

      Would like to

      Would like to dimension tan to tan, but print is calling out center to center.

        If you have access to the engineer, ask him or her to change it and explain why. If not, report it center to center. I don't know how much leaniancy you have but if it were me and I have a lot, I would report it tan to tan and do a cen to cen as reference.

          I guess the only problem I see with this is the "SLT1.DIAM". Since it is a slot, it has a radius at each end. One could be different from the other. I haven't done any round slots but it seems to me you need to subtract the measured radius of one end and then subtract the measured radius of the other end. I'm not sure if you can do this.

          It is probably easiest to do a circle at either end as inspector212 suggested.

            I just finished running some parts with 1 side and 1 end of round slots being dimensioned instead of the CL. I created variables from the measured slots then created generic points using the variable values. Below is a portion of my program. Someone with more experience may be able to accomplish the same with less code but this worked for me.

            If you're wondering why I dimensioned each one twice. Once for variable creation only, the second for sending to Datapage.

              Try this

              Boomer,

              I did some testing in my program. First, the slot I measured is .210 x 1.710 along Y axis. The CL to CL dimension would be 1.500. Below I figured out dimensioning the CL to CL dimension using the values from an auto round slot.
