Interfacing ProE Wildfire 2.0 with PC-DMIS

Interfacing ProE Wildfire 2.0 with PC-DMIS

Interfacing ProE Wildfire 2.0 with PC-DMIS

(OP)
Hi everyone,

I am doing a feasibility study (cost, ease of implementation etc) on implementing a ProE - PC-DMIS link in my company.

I was wondering if anyone out there can provide some help with the following questions:

1) Is the conversion of CAD files to CMM inspection programs widely used? If yes in which industries?
2) Within PC-DMIS there is an option to either "interface" or "import" ProE models. What is the difference, pros and cons between the two approaches?
3) In order for PC-DMIS to import the CAD file (ProE in this case) does the CAD model need to be constructed in a special way?
4) How does PC-DMIS handle/ interpret GD&T for features within the CAD model?
5) How does PC-DMIS handle "bluff" dimensions? An example of a bluff dimension is a generic length, say "L1" on a drawing. The actual value of "L1" will be stated else where.

I have many more questions on this subject, but perhaps starting with this is sufficient!

Thank you in advance for all the help.

RE: Interfacing ProE Wildfire 2.0 with PC-DMIS

    I'm in the process of assessing our CMM's capabilities or lack thereof, and recommending a software upgrade and/or equipment upgrade for the very purpose you have stated.
    Our dream desire is to have the CAD Model translate into our CMM using PC-DMIS or a reasonably similar program, and then probing the part according TO that CAD model.
    There are fixturing repeatability issues, as well as some manual set up issues but I'll respond to your numerical points:

1) I'm finding this is typically done in more modern
   facilities that have the $$$ to buy into it.
2) "Importing" sounds like PC-DMIS would use the program
   data without any additional feedback from the CAD; where-
   as "Interface" implies a continued communication with
   the CAD.  Personally, I'd like to be able to have real-
   time adjustments on an "Interface" level.  
3) The presumption is that the creators of the Software
   anticipate the various forms of CAD file construction
   that are out there, so I'll assume for the time being
   that in your Help files in ProE, you should be able to
   learn what CAD file forms are able to be used by it.
4) Since G.D.&T. is widely used, again I would believe that
   ProE would be able to cope.  There may be manual steps
   to enter the tolerances and conditions, which I would
   prefer.  I don't want the software to "assume" things
   by default.  
5) "Bluff Dimensions" are used on some of our prints and
   it would make sense that you would be required to fill
   in various fields such as this.

RE: Interfacing ProE Wildfire 2.0 with PC-DMIS

I took a look at their website.  http://www.wilcoxassoc.com/home.htm  It looks like you have to have their Direct CAD Intefaces (DCI) to be able to read in tolerances and GD&T info.  IGES or STEP interfaces are just going to give you a block of dumb geometry and you will have to input all the tolerances manually.  

I expect you would have to have family tables of parts to handle the "Bluff Dimensions" with a different program for each part but there was no mention of this senario in the info I read.

Hi Guys,
I have been doing some additional reading on the subject and I have summarized my findings in a word document. Is there a way to post this on the forum?
