Trying to create a plane off the stand pins to be able to zero out on it.

Rebecca Stahlhut

Hello,

           I am new to CMM programing and have hit a snag. I am trying to create a plane sperate from my CAD drawling so I can raise my part off the granite. How ever I need this plan to allow me to zero it. Like you would do for a manual CMM. When I went to program the plane, I told the vectors that it was <0,0,1> instead of <0,0, -1> . I leveled and origin to the plane in both manual and DCC. Then moved working with the CAD drawling, I was hoping that when I create a plane on the inside of the part that it would recognize that the part was on top of the plane. 

           How ever after I finished doing the manual and DCC alignments for the actual CAD drawling and then went to do the first play though, the CMM errored out each time after trying to take the first four hits for the plane underneath the CAD drawling. 

          So, my question is, is it possible to create a raised plane off the granite and if so,, how do you do this? Any help would be greatly appreciated, thank you for your time.

    So if you want to raise the part for example, let's say in Z+ workplane you want to be 6 inches from the Granite, you'll touch off the granite to make your plane, then do your alignment for your origin and level, etc. Then inside of that alignment you will offset 6 inches in Z by value of 6, so that your 0 is 6 inches in the air off the granite. But I do not understand why you want to entirely yet.

    If you raise a part on a fixture or posts, whatever you use, the machine will be able to find where it is within it's own parameters after you do your first manual alignment

    And what  said, posting your code would help
