  • Scan Diameter best method what settings should i use?

    I need to scan this diameter, what is the best way to go about this? i need all the points i can get. trying to get the best circularity profile i can to compare to cad. 2018 R2

    BOTTOM DIAMETER =FEAT/CONTACT/CIRCLE/DEFAULT,CARTESIAN,OUT,MIN_CIRCSC
    THEO/<-14,0,0.0653>,<0,0,1>,0.6232,0
    ACTL/<-13.9999,0.00039,0.06456>,<0,0,1>,0.62526,0
    TARG/<-14,0,0.0653>,<0,0,1>
    START ANG=190,END ANG=-125
    ANGLE VEC=<1,-0.0000152,0>
    DIRECTION=CW
    SHOW FEATURE PARAMETERS=NO
    SHOW CONTACT PARAMETERS=YES
    NUMHITS=16,DEPTH=0,PITCH=0
    SAMPLE METHOD=SAMPLE_HITS
    SAMPLE HITS=0,SPACER=0
    AVOIDANCE MOVE=NO,DISTANCE=0
    FIND HOLE=DISABLED,ONERROR=NO,READ POS=NO
    SHOW HITS=NO

    Maybe change DEFAULT to analog scan strategy ?
    Or use basic scan circles...

      that code is from just taking hits but i need to do a scan all the way around with the scanning head.

        If you open the auto circle window, you shoud find the strange button (in red).
        By clicking on it, you will be able to choose "analog scan strategy", and let PC-DMIS choose the right parameters.

        Under the 2nd tab from the left at the bottom of your Auto Circle Feature box, change the strategy to Adaptive Circle Scan. From there you can change the points per mm to whatever you like. Or, you could do a basic circle scan as JEFMAN suggested. Or, you could do a linear closed scan and then construct a circle out of the scan.

        Thanks , I didn't know they had the manuals online. our local sales guy wanted me to take the course again i think as he didn't tell me that information.
