Pas cmm

Hi all I was wondering if anybody out there has had any dealings with PAS Cmm

we have had somebody come into the firm to demonstrate it (I was not there at the time but somebody else took my place)\

it seems ok but I am a little concerned about the amount of support for it

in the UK it seems to be fairly expensive for the amount of benefits it gives compared to PC-Dmis

we also use a lot of custom scripts which it also doesn't support and would have to be edited in using PC-Dmis

they are trying to sell it to us for a month and they say that they can train people in four weeks to use it !

sorry if I sound a little sceptical (a dinosaur with over 20 years experience).

I am currently using 2016 MR4 and have asked hexagon to send in an apps engineer to asses my programming to see if I can do things quicker

personally I do not believe it

I would prefer for that amount of money to be spent on a renishaw sp25 scanning probe as this would speed up my programming by not taking single points to do constructions and scanning the surfaces instead I also hope we might see some speed increases on the cmm as some features are large bores approx. 1100mm diameter 72pt construction with 3mm prehit/retract compared to scanning has anybody seen this or is it just wish full thinking

We have upgraded recently to the SP25 and it depends on what your product mix is. We utilize the TTP adapter for some programs, but where the SP25 shines is you can really ramp up your data density without trading off speed. There are sometimes that the TP20 is faster for us, other times when we are looking at tight tolerances where the SP25 really fits well. It isn't a one size fits all answer.

Where are your bottlenecks? Initial part programming? Actual inspection time? Combination of both? How exactly would a different software address these issues? Maybe bringing in the Hex app engineers might help.

The sales person's job is to sell product, so of course they are saying that their product will address your issues better. Maybe, just maybe 25K spent elsewise would be a better investment (probe rack, fixturing, etc).

My .02, which according to the stock market is worth even less...
