SPC Software

Aside from DATAPAGE, what softwares has anyone found and used that works very well hand in hand with PCDMIS for doing SPC charts, 6 sigma, cpk analysis, etc., inprocess to the product run? Thanks as always

  • What is the scope of your implementation? This plays a major role in the decision process. Are you thinking corporate-wide?, for your site?, a particular shop area? Is it OK to have the data buried on the island of the cmm computer? Or does it need to be available to the production and quality manager? Do you need to collect data from just the cmm, or other devices as well? (digital calipers,mics,air gages).

    So far the scope is only site wide, we do have two other sister sites but ill focus on one for now, trust me that will be enough work in itself. I want to make it so anyone who is interested in the office can access the data. Minitab for example do a perfect license for this, you can install it on as many computers as you want but you can only have 5 concurrent users. At the moment it is just collecting the data from the CMM. We do however have spc software on standalone machines that currently are used as a go nogo gauge for the operators as no-one looks at the data, so pointless. I want to try and make that data accessible in the future as well.

    And this is really important: Someone (on each shift) in the organization is going to have to be responsible for tending to the data. Following up on bad/bogus results, rechecking dimensions and correcting the data, etc. It's a time consuming activity. But if it isn't done religiously, you'll end up with a bunch of data you wouldn't want to send to your customer. Unless every part you measure on the cmm is perfectly deburred and cleaned, you never have a tip out of calibration, never have a part misloaded and all the hundred other things that can go wrong during a cmm inspection...

    unfortunately that is going to be my job, fortunately however the part numbers are low enough to quarantine the parts so I can double check if anything is wrong when I'm in work.

    About 5-6 years ago, way before I joined they had here a quality engineer on each shift. Now we don't have anyone with that title here, it is kind of my job for dimensional issues. Only now is management rethinking its approach of not having quality technicians and engineers.




    I did look into QC-Calc but it seems more of a real time display which I think would work if we were measuring a part every 5 mins. Or have I got the wrong end of the stick there?
