Hello everyone.
I have a question regarding a new tool selection.
There's a dimension (10 ±0.1) and a new device that we bought to check it - it's a sensor with a resolution 0.01. I chose the resolution by comparing it to the dimension's tolerance (according to the MSA Manual it's 10% of the tolerance.
I tried to calculate a Cg/Cgk for this (50pcs measurement) and the result was always 10.02 therefore the Cg/Cgk result was really huge.
Right now our client claims that the resolution we chose was not correct because we can't see any deviation.
What is your opinion? (who's right?)
Should we buy a new device or the one we have is sufficient?
In my opinion they are not right.
Thank you in advance.
[EDIT]
Attached an example how do the results look like
