Happy New Year Everyone,...
,
I am currently working on CMM calibration frequency and variation.
Problem definition: We have morethan 25 CMM's in our manufacturing site, and it costs us lot of money to calibrate the CMM's. We are targeting 12 or 18-month calibration, current calibration frequency is less than 9months and in many cases it is less than 6 months....
There are recurring problems with the CMM repeatability, reproducibility and between machine variations in the manufacturing cells.
Example: I inspected the same component on different CMM's and the results varies between 3 to 6 microns within the machine and 14 to 24 microns between the machines,.... .
After these findings, now I am looking into
1. The compressed air quality supplied to CMM operation,
2. The influence of temperature (it varies between 23 to 27 degree Celsius),
3. The interface error between the OEM and Renishaw head,
4. Quality of Air filters used
5. Daily maintenance etc...
Has anyone come across this sort of situation before? Please share your views and experiences
Have A Great Year Ahead!
Cheers thanks,...
