  • Multiple alignments

    Has anyone tried to use a multiple alignments?
    The program works and it measured all the feature up to the second alignment. When i ran the program, the orientation of the camera is still on the original position. Below is how i set up my program:

    I established CAD/PART orinetation, and my 1st alignment. I created all the features to be measured looking down the part. Now, I want to measure the side view of the part. I established a new origin (as my second aligment) and inserted the "Equate Alignment"

    Hello,
    If I understand properly, You have not set "Equate Alignment" for your first align.
    - one way, create your first align like the CAD and set "Equate"
    - Or click on the cad feature to be measured, measure manually this feature on the part (2 or 3 elements is enoiugh), and create an alignment (the CAD follow atumatically the measure), and continue to click and measure, you can create how many alignment you want...

    (sorry, for my English :-)

      If I understand correctly JacobMag, you wouldn't use EquateAlignment in that instance. It should be noted, alignments for pcdmis vision are the same as for pcdmis cmm, and you can have as many as you wish. Each time you want to create a new alignment, either use the 321 alignment wizard, or insert new alignment and select your level, rotate and origin features.

        Multiple alignments

        Thanks for the replied.

        I have not tried the Wizard 321 alignment. But, I tried creating new aligment and it does not seem to work. The reason is that the vision camera is looking on the side view instead of looking down. The problem might be that the 1st and 2nd alignments may not be pointing at the same ways, the cad/part machine maybe different between the two alignments. I have to double check this and try it again, and I will try to find out how to use 321 alignment.

        I am new to PCDMIS and i am trying to find my ways to run the program.

        Thanks again,
        Jacob

          multiple alignments still not working 4 me

          I am still struggling to set up more than one alignment in the program, and moving or re -positioning the part from top view to side view.

          Can someone give me a detail steps? I have tried Align Equate, and inserting new alignments in the program....but nothing works. I am a bit frustrated now.

          Thanks,
          Jacob

            Well I have never used the vision product, but nkWAI says it is just like the cmm version which I know well. Are you changing workplanes after you insert the new alignment? Do not use equate for what you are trying to do. If you have a block and the top is A the front side B and left side C your first Z+ , (or top view looking down on the part), would be a A/B/C alignement and you would be using a Z+ workplane to measure holes in A. Then if you switch to a front view your new alignement might be B/A/C with a Y- workplane to measure holes in B.

            Also in pc-dmis cmm the grapics window can be configured to show multiple workplanes simultaneously or any single work plane of your choice but the graphics window does not automatically change perpective based on what you do in the program, it has entirely seperate controls. HTH

              Unless you use a rotary or a fixture, changing the part view from top to side will require a completely new Alignment. Using the vision alone, you cant effectively tie together two alignments.

              So if you are rotating the part, start with the "Startup" alignment on the new side. To reduce the graphic confusion it might be easier to start a new program for "Side 2"
