Re: Concentricity reporting

As best I can, using your values on your report, I do not come up with the same concentricities as you do with the same positional errors for each. I get expected results in CMM-Manager compared to manual calculations. In order to evaluate further, we will need a copy of your program so we can revie...

Re: Concentricity reporting

In all cases here, with no further context and data, it is difficult to figure out on a case-by-case basis what is going on. With the information given, Ryan Christopher's post is probably the best answer that we can give for now. In the picture above, were the circles measured as a circle on either...

Re: Locating rack

As far as probe inhibit after dropping off the probe - the doors MUST BE CLOSED after locating the rack.

Re: True position of a point with angle

At this point, it APPEARS to me that the problem may be the original definition of the point itself to measure. I'm assuming you picked from CAD and it looks like the pick may have been slightly off. Without the program, I'm guessing. Double click on the point feature in the Program List and go to t...

Re: CALIBRATING THE CALIBRATION SPHERE?

Except. You would have to calibrate you tool on a certified artifact to start with. Which means you can't calibrated your probe on the sphere and then use that probe to check the sphere...

Re: 3.9 SP2 save file issue

I also cannot make it fail in 3.9 SP2 or 3.10 in English. If I change the name to .prg but *do not* change the type it will save as part1.prg, but the format is still .cmp and will not open (unless I rename it back to .cmp). In English I cannot get the strange part1.prg.cmp format, but that may simp...

Re: CALIBRATING THE CALIBRATION SPHERE?

Here's what NIST says about this (essentially what I said in the first answer): How often must I calibrate and instrument or artifact? You need to calibrate often enough that the instrument or artifact is known well enough that the quality of your product is not adversely affected. You must know wha...

Re: Feature report for a cone that includes the base diameter

Under Construct > Circle you have two options.

You can intersect a cone and a plane (measured/measured, or measured/nominal) and get a diameter at that height. Or, you can get the height on a cone where a specified diameter occurs.

Re: CALIBRATING THE CALIBRATION SPHERE?

The answer totally depends on your, and your customer's, requirements. You determine this statistically. In a perfect world, you would send you sphere out, say, once a week for a few weeks. After you see it is stable, you would then switch to maybe once a month. And after that is stable a few times,...
