alignment

Ok so I am trying to get familiar with pcdmis 4.3 without reading the massive manuals. My shop has had a 2.0 arm and this software for quite some time without really being used much at all. our programs are written for virtual dmis and in use with old arms that no one will even calibrate anymore.

I am currently stumped as to how to make the correct cordinate alignment. I am writing offline with only prints no cad. Using datum A plane a line constructed out of Db and DC . I want to referance x and y back to DB circle with a -27.45 rotation on the x.

Can anyone please walk me through this.

Thanks in advance,
Christopher

I guess my first measage on this forum seemed offencive sorry for coming off as a dumbed down dummy who wants to sap information out of your brain.

Sorry you are offended we are reluctant to give you bad information. Most of us take our careers pretty seriously. We are good at what we do, but we spent years learning to get where we are. We did not just log in here one day and say, "Here I am, what do I do?"

Pc-Dmis is a complex software. Alignments are critical in both CMM and surface plate inspection. Learning to do them properly really requires training and practice. The concepts are too abstract and the possible variations too vast for anyone to learn this via a web forum. We could easily give you a basic run through as John Kingston just did, but your part might fit a simple 3-2-1 (plane, line, point) format.

Furthermore we have not even gotten to the black art of GD&T and how you determine which features to align to, much less how.

Heap on top of all that the fact that you start off by saying you don't want to be bothered to attempt to train yourself by reading the manual. . . what do you expect?

The help files actually have some pretty good basic alignment explanations. However I caution you again that if your alignment is not correct, none of your measurements will be. I will generously guess that you, like so many others, have been volunteered to "be" the CMM guy. This is not something you can learn in an afternoon, a week, or even a month. If you have arrived at this point with no GD&T, no surface plate experience, and no CMM experience, it will take months of intensive training and study to achieve a minimum level of proficiency. The salespeople won't tell you that. The management doesn't want to hear that. It is still the truth.

Rots-O-Ruck!

If you stick to this, after you have had some training, when you run into a wall, search this forum, you will probably find the answers you seek. If not, then post as specifically as possible, with as much info as possible, (code and drawings are often necessary), that is where and how this forum can be an invaluable resource.
