PC-DMIS Gear 2.5 verse Qunindos Gear 7?

michelle
Hello there.

My requirement is to measure and report on SPUR (straight, helical & double helical) and BEVEL (straight, spiral) gears. Could anyone share an opinion on PC-DMIS Gear Verse Qunindos Gear?

Additional questions:
  1. Am I correct in thinking that whilst both software packages cover my measurement requirement, Quindos is more comprehensive (and complex)? Is it overkill for my requirements?


  2. I read here that PCDMIS gear use advanced gear measurement algorithms of QUINDOS - is this true?


  3. Since Quindos is certified by Physikalisch-Technische Bundesanstalt (PTB) of Germany - is the same true for PC-DMIS?


  4. I read here for Quindos that all travel paths, probing points and scanning lines are created automatically - does the same hold true for PC-DMIS Gear?


  5. Why has Hexagon developed two different software packages for gear inspection? (What is the history?)



Thanks in advance.
  • I started with Quindos and moved over to PCgear.

    #1 They all have the power to do what you are looking for. Quindos was overkill for us.
    #2. Yes Quindos will do anything you can think of it is how ever nothing like PCdmis at all.
    I do not run bevel gearing I do run OD gearing straight and helix and spline shafts, ID gearing straight and ID splines. Quindos and PCgear use the same style K-chart.
    #3 Don’t know about Quindos, I check to Agma standards in PCgear. PCgear checks other standards also.
    #4 PCgear will also creat gear checking programs .
    #5 ????

  • Thanks very much for your reply EZalg as it was really useful.


    • I obtained a sample report from PC-DMIS Gear (attached in case anyone else is looking for one)
    • I am awaiting a reply from PTB (Germany's national metrology institute) and will post back here on certification confirmation for PC-DMIS Gear
    • On Gear Standards (from hexagon here): PC-DMIS Gear supports a wide range of international (gear) standards including AGMA 2000-A88, DIN 3962, JIS B 1702 and ISO 1328

  • Just to close off this post - I had a reply back from PTB ( G ermany's national metrology institute) - although Quindos is certified - PCDMIS Gear 2.5 is not.
  • Hmm...

    Specific versions of PC-DMIS is PTB certified and it seems that as long as the internal routines for feature creation hasn't changed between versions, other version should be "certified" as well (technically speaking). PC-DMIS Gear is an external program that generates the PC-DMIS program to measure the gear but the gear evaluation is done in Gear.

    Hi VPT,

    Yes I thought so too. And in fact just about everyone I asked told me yes it is. But PTB definitely verified that GEAR 2.5 IS not certified.

    I've attached the email which was sent to me from Karin Kniel from teh department of coordinate metrology.

    PTB is Germany's National Metrology Institute.

  • The difference could be that the Quindos Gear creates the features natively, the gear program constructs the features directly and not using another program for feature generation. PC-DMIS Gear is just a front-end for the feature generation (which is done in and by PC-DMIS) and here is what I would say the major difference could be - Quindos Gear is a program with native feature generation, whilst PC-DMIS Gear is not.

    I don't use any of the software, but I do know that PC-DMIS Gear does the evaluation and PC-DMIS program generation (and some PC-DMIS versions are PTB-certified) but PC-DMIS Gear doesn't generate the features, thus no need for it to be PTB-certified?
  • I know I have personally tested it against dedicated Gear checking machines from 2 different manufacturers and Gear was right in line with them. It does use the same calculations from Quindos so they should be essentially the same. The reason they offer 2 different packages I'd imagine is PC-DMIS users needed an easy way to check gears without investing in a whole new software. Quindos Gear can check more types of gears but PC-DMIS Gear is great for the simple application of Spur and Bevel Gears.
  • Hi all. In order not to start a new forum , I will continue in this one . Our production measures the gearing of the rack and pinion of the steering gear. We have to buy special software for PS DMIS. This is either PC-DMIS GEAR or QUINDOS. Our gear has a very steep involute. Parameter 26 on the drawing. The seller says that GEAR cannot cope with such teeth and will not cane scaning . And it also cannot change the angle of the probe on the same tooth. But QUINDOS is easy to deal with. The cost differs by a factor of two and a half between these two software. Does anyone have any experience with these measurements. Maybe there is an easier way to measure such teeth?
