Hi all,
I am currently having a debate with a CMM programmer on my staff. He insists on using the fixture co ordinate system when measuring parts. I completely disagree. In my experience, which is about 7 years worth, you always fixture a part in a reliable, repeatable way and according to the print datum’s, you build your part csy from those datum’s. Independent of the fixture.
The only time I have ever seen a fixture coordinate system used, was on a machine that was dedicated to a couple of specific parts, where the fixture never moved. Then fixture csy was only used by the machine for a rough idea as to where the parts are positioned. Once the program completed the fixture csy it would then measure the part csy and continue with the rest of the measurements.
Anyone have any feed back or have experienced this before, Id appreciate your comments.
