    How to create manufacturing process drawings?

    Charles Hilton

      What is an efficient way to create process drawings for a part?

       

      I am a manufacturing engineer at a 5-Axis CNC machine shop.

       

      Problem:

      A turned (revolved) part is split into halves, using the top plane. The two havles are saved into seperate .SLDPRT files, and features unique to each halve are added them. The two halves are then used in an assembly, with the intention of using that assembly to create a final machining drawing, so as to detail each halve.

       

      My own method for creating final drawings and in-process drawings, involves using "Model Dimensions", so that I can bring in dimensions from the model to make sure that all the required dimensions to make the part are in place. Within a part file, I dimension and tolerance everything within the sketches and features, making sure that each sketch is fully defined.

       

      When I try to create a final drawing, or an in-process lathe drawing of the part using the aforemention assembly, the problem I encounter is that dimensions in the orignal part file (the one used to create the two halves) don't come in, because only the solid bodies, not the dimensions and features, are brought into the two part files generated by the split feautre for the halves. To prevent myself from having to dimension the whole thing over again and having to updated multiple instances of the same dimensions relating to the same feature in the event of a design change, how would I bring in dimensions existing in parent files?

       

      The enclosed ZIP file contains an example of my current situation.

       

      PN001.sldprt is used to generate the files PN001A.sldprt and PN001B.sldprt, which are then used in the assembly, PN001.sldasm. PN001.sldasm shows the parts at their final state.

          I think a more effecient way is to use configurations in your part file to represent the different machining operations. For example create on configuration for turning and add a second configuration for the milling to be performed after the turning. You can then show both configurations in a drawing.

            Good afternoon Charles,

             

            After reviewing your comments and part/assembly file this is the way I would approach your Assembly/Parts, however I don't know how many different scenarios you may encounter, which would possibly change my approach also.

             

            1.  Model the one half and then mirror the part which would take the split part out of the equation.

             

            2.  Take the 1st modeled part and the Mirrored part and insert those into the assembly

             

            Then you could create a design table of the original half to change your assembly part requirements, or you could also try using the Drive Works Express. 

             

            The nice part about SW there are other options available and it really comes down to preference coupled with experiences, therefore the above is my two cents, there are probably a lot of other ideas out there.

             

            Later,
