Ok so I followed a former boss to a new shop, he needed a programmer, but the problem is that this new shop has a whole host of B&S PC Demis CMM's, and I have all my years of experience in Zeiss Calypso.
As far as I’m concerned the difference couldn’t be any bigger, other than general terminology there is nothing visually or procedurally the same going from one to another.
I’ve been at it for about 2 months now and I’m still having trouble wrapping my brain around the code like structure.
I went to the beginners’ course at Hexagon in Wixom (Detroit) Mi., but all I learned there was what all the icons do.
I’m chugging along now, churning out programs at increasingly faster speeds, but it’s only with great effort and eye strain (And leaning forward).
I
DO sorta like the flexibility of the articulating head (Although I do question the accuracy).
I
DO like the resistance to breakage due to the probes being held together by magnets and the TP20 range of motion.
I
DO NOT like the heavy use of individual "Hits" instead of the scanning head on the Vast Xt (On my B&S that’s a different attachment)
I
DO NOT like that you can’t just qualify all the probes in the rack at once, you have to open different files and qualify the probes used in that file, then open another file and qualify those probes...... and so on. (To better explain, the qualifications seem to be tied to programs, instead of being a machine function)
I
DO NOT like the use of “move” or “clearplane” points, in Calypso the probe just moves in and out of the part between features pretty much automatically.
I
DO NOT like the Stability of the Demis platform (see all the threads in here about unexplained shutdowns and program crashes).
So here I am, learning a new language, finding a new way to get around, trying to put a new feather in my cap.
For those of you who are multi Lingual, what do I need to know to make my life easier?
What have you found that Demis does better than Calypso?
Fyi,
medical implants (Knees, Hips, and spinal)
Lots of line and surface profiles
.001-.002” profile tolerances are standard
Cad models for everything.
Many years ago after 9 years as a PC-DMIS programmer I was desperately looking for work (was a victim of downsizing). I found a job but it was programming C@!^pso. I figured it must be similar and just like you found it to be substantially different. I am now back to programming PC-DMIS after convincing the company to get a B&S machine. I know the differences very well. Don't lose hope because PC-DMIS has many, many shining qualities.
The first one to mention is the Edit Window: I always run from Command mode, almost everything is there to edit or no more than one click away (you don't have to dig through dialog box after dialog box to change stuff).
Vectors: You will need to learn vectors because that is key to PC-DMIS. Yes, in Calypso you could see vectors but you couldn't touch them.
Calibration: By no means are calibrations tied to programs as a matter of fact calibrations are extremely powerful. Yes, it is true that you have to be in a program to calibrate a probe but it doesn't have to be the probe used in that program. You only need to calibrate what you need to (Mark Used) and if you need to change to a different probe you just select the probe you want and the A,B angles all, by design, match (no choosing which left or front goes with which right or back) AND you don't have to requalify every probe every day.
Points: Yes, PC-DMIS is all about points. It's about making collections of points that are points, circles, cylinders, planes, scans, etc. Calypso is all about circle functions, cylinder functions, plane functions, etc. With PC-DMIS you are able to precisely position points and precisely position points based off of other features to measure features that you never thought were possible before. I do it everyday.
Patterns: In PC-DMIS you can create a feature, a constructed feature, a dimension, and anything else related. Select and copy all of this. Then create a pattern and everything is patterned into new features. (all just as easily editable as the original, not "locked" up inside of a pattern function).
The CTRL keys: ctrl U (run program from cursor position), ctrl E (run single feature), etc are very big allies.
Alignments: alignments in PC-DMIS are very, very powerful, not limited to only using specific features, and not limited to the amount of constructed features you can use. One thing I did like about Calypso was you could rotate to an X, Y, Z coordinate in "space". In PC-DMIS I do a construction between two separate alignments to accomplish this. In PC-DMIS alignments are "daisy-chained" throughout the program (each builds off of the previous) or recall alignments bring back previous alignments. They are not "tied" to each feature.
All in all I find that I am at least 3 to 4 times more productive and by far can measure parts more comprehensively than my Calypso counterparts. So don't be discouraged, it is a little bit of a learning curve to switch.
