SOS on coordinate system changes

RobOntario
Hello all.

I have a mature program for part, with fixture program and part program. One of big guy wants to rotate the coordinate system: X as -Y, Y as -X and Z as Z, any easy way to do it?
Can I setup a new alignment when I do the reporting?

Thank you
  • Hello all.

    I have a mature program for part, with fixture program and part program. One of big guy wants to rotate the coordinate system: X as -Y, Y as -X and Z as Z, any easy way to do it?
    Can I setup a new alignment when I do the reporting?

    Thank you

    Well, you can make a NEW alignment program (fixture program) using the new co-ordinate system. IF it is just a straight-up 90 degree rotation ABOUT XY zero, you then just make a new program to check the part, recall the external alignment from the fixture program, then PASTE WITH PATTERN from the original part program into the new part program. You may or may not have to futz with the probe angles, but that should be all you need to do.
  • I assume that the big guy wants the CMM axis to match the machining axis.

    If the dimensions are at the end of the program then just do the rotation and reconstruct the report. If dimensions are reported after each feature(s), it's more complicated. Basically, the process would be: create feature, rotate, report, rotate back.

    NOTE: I don't think that the part can be rotated as described. If +X is to be rotated to -Y then +Y would be +X.
  • The big guy wanted to match car coordinates system. I would like to export 2 coordinates system from fixture. One is previous one , the other is rotated one. At the end of part program, import the rotated one to do the reporting for ABC. And change the DEF in part program too.
    by the way, can we change X Y Z at alignment by 90 degree without calling any features?

    yes.
    align/rotate A degrees about B Axis.

    Also if you are fundamentally changing the entire routine, and your cad is maligned, you can open Edit-> Graphic Display Window-> CAD Assembly
    then within there, rightclick on the entire cad assembly file and select "transform". you can rotate and translate the native cad origin to anything you want.
