Re: CMM calibration recommendations
Where are you finding glass stylii? I'd be interested in looking at their web site to see what advantages they claim, especially with regards to scanning on cast iron and aluminum.
The tips as mentioned are not plastic but glass which has a coefficient expansion of zero. The probe will wear and must be changed out periodically. If you view a probe under a microscope you will see evidence of wear.
As far as an outside calibration service if they are not able to adjust the mapping software then it is only a verification that the machine meets the OEM specs. If you purchase a Renishaw Ballbar kit you can do this yourself and save your money. It is best to have the OEM or their agent come in an do the calibration for obvious reasons. Changing the mapping software should not be left to just anyone.
