Hello folks,
I am being tasked with a task for an R&R on our CMM, and though it seems simple enough, I realize there are several ways that are possible to structure the tests. I wanted to get some input about methods and see if it makes for a better result, as I am very "green" with the CMM and certainly could use some more exposure to data analysis and reporting as well as constructed features.
It should be noted as well, that I am not familiar with constructing features, and really need to know best practice more than line item instruction. I have not had enough exposure to reporting, constructed features, or looping enough to known how to put them all together, but seemed logical to bring it up here to the forum to get some insight.
Here is what we need to do;
Measure a .250 Block 25 times using 4 points in each gauge end report to the 5th decimal.
Measure a .500 Block 25 times using 4 points in each gauge end report to the 5th decimal.
Measure a 2.00 Block 25 times using 4 points in each gauge end report to the 5th decimal.
Measure a 4.00 Block 25 times using 4 points in each gauge end report to the 5th decimal.
to recap
Requirements of the job are that I use 4 points on each end of the block in the analysis, repeat each measured block 25 times.
I assume that I will have to construct all the features to make sure the points are all directly opposed to one another, and vectors are clean and repeatable, also, analyzing them as individual points and not referencing them relative to another for a location will be important to determine repeatably.
Also reporting to the fifth decimal is new to me, but that will be an easy change once the program is done.
The task seems very simple at first, but I then think about ways a program can be written that is flexible enough to allow for measuring the 4 lengths with minor editing.
In addition to the open architecture of the program, I am needing to report it to the fifth decimal.
As previously mentioned, I am new to PC DMIS My Software background is Solidworks2013-present /MasterCam v8-2017 /GibbsCam ver 8-12. So when it comes to PC DMIS I know just enough to be dangerous.
In short, Im curious how the FOGs would set up this job My thinking is to fixture the blocks such that one edge will always fall at a stop and thus be common, then a constructed parallel line will float with the blocks at their indicated length (.250". .500", 2.00" and 4"00") four points would be taken at zero, then a constructed group of points which can be moved in the length axis, I know this is low level for many people here.
Also eventually looking into the possibility of changing to reporting in Excel
But I know there is likely a resource that I could be directed to that will help. So. Thanks in Advance.
