Hello,

I have clamped a part on my CNC Mill.

Yesterday i measured the size (by a DTI) & it was showing 100.134
Today i measured the same parameter (by a DTI) but it was showing 100.124.

There is an error of 10 microns...
Then i checked the reapitability and it was showing within 3 microns...So, 1 thing is confirmed that this is not a reapitability error.

How cum there is such error ?
Is this error occured because there was a time interval between the measurements ?

Thanks
Ashish
