Alignment to offset holes?

Stephen McMillan
Hi all. First post. Sorry if it's a rookie question.

I want to do a Plan-Circle-Circle alignment.
The first hole is the x0 y0 origin.
The second hole has some given coordinates, say x8.0, y4.0.

I don't want to have to calculate the angle and use the "Offset angle" in the "Rotate to" field.
I also don't want to use an iterative alignment.

Any ideas?

Thanks,
Steve

  • Some CMM software allows you to rotate to hole’s coordinate, some don’t and PC-DMIS is one of them, but you can achieve the same result by using math in your part alignment and let PC-DMIS calculates it for you. Try this: 

    A3         =ALIGNMENT/START,RECALL:STARTUP,LIST=YES
            ALIGNMENT/ROTATE_CIRCLE,XPLUS,TO,CIR1,AND,CIR2,ABOUT,ZPLUS
            ALIGNMENT/ROTATE_OFFSET,[COLOR="red"]-(RAD2DEG(ATAN(4/8)))[/COLOR],ABOUT,ZPLUS
            ALIGNMENT/END

    thats some sweet chit lambo - I'd rep ya but the crapped up rep button won't let me
