Undimensioned Features

cmmjdl
I'm looking for an option that appears in Zeiss' Calypso hoping that there's a similar approach with DMIS.
When programming a complex part with a model, I like to program around the part in a logical manner measuring all features
I can reach. I then dimension what I've measured to the customer's drawing. There are occasions where a feature on the part
is not dimensioned on the drawing but I've measured it. Calypso won't run a non dimensioned feature thereby leaving that feature grey as an indicator is wasn't dimensioned. This prevents me from missing anything on the part whether it's been dimensioned on the drawing on not. DMIS on the other hand will measure everything, dimensioned or not.
Is there a way for me to tell that one of say 500 features is measured but not dimensioned with DMIS?

Thanks
  • No you can still run all features it just depends on how you want the run sequence to be based characterisics based or feature based its been a few years since I used Calypso so things may have changed.

    excuse my ignorance about Calypso but I am asking merely to understand what that software can do. So how does one write a program? Are there no Moves To's between features? If not how does it get around the part and go to other angles and the bottom of the part? when you switch between different features or by dimension how does it not crash?
  • You program much the same as dmis using a clearance zone around the part at allow it to navigate but you can on later versions still use move points. The first versions I worked on had a limited move feature so you had to use clearance and sub clearance moves to navigate.

    One of the big differences is that you set the run sequence by characteristic (dimension) or feature (measured) Calypso has 2 edit lists(windows) features and results. If you select run by characteristic it will only run the feature for which you have requested a result.

    Now as Calypso's navigation is set to the feature and can be modified independent of the main clearance zone with sub clearance and if you have forgotten to dimension a feature that uses the main clearance zone it will move to the next feature. If that feature is using the same sub clearance as the next feature in the characteristics list the probe will move between them without coming out of the clearance zone and could cause a crash.

    That sounds exactly like one of the things you can accomplish with the PC-DMIS "Mini routines" (under File -> Partial Execution).

    This is true but with limitations. The "Mini Routines" needs the Clearance Cube activated to work correctly and the Clearance Cube in PC-DMIS is more in a beta stage when using CAD assemblies with a CMM Fixture Plates.

    In a nutshell, no!

    As it was already stated you have to use the clearance cube to use the "mini routines" and it is a bit confusing at the moment. I know exactly what you are talking about but at the moment PC-DMIS doesn't have that capability in an easy to use way.
  • The question could be rephrased as "Can PC-DMIS tell me if I have features that are measured, but still not dimensioned in the program?". If I have measured a plane, but not dimensioned it (in anyway) can PC-DMIS remind me of this?

    (The short answer is "No, not without a lot of work")

    There are "things" you can do. If you put all dimensions at the end of the program, you can UNMARK all, then go to the dimensions and mark JUST the dimensions. Any feature that is dimensioned will then also get marked. You can then look at the graphics screen for any feature that does not have the * at the end (the * means it is marked).

    OR

    Again, requires you to look, but if you have a nasty color scheme for unmarked and marked features, do the same as above then scroll through the program.

    But nope, other than those, I know of no way.
  • Matt, that's a way of using UNMARK/MARK that never occurred to me, thanks! But it only works if Edit -> Markings -> Parent mode is checked.
