Hi everybody
As a newcomer I have the question about machine capability analysis.
1) We have 4 CNC machines. Then we machining one reference part (reference part means: all parts have the same shape), three times in each machine. This meeans that we have 12 machined parts. [cosider a 12x500 table]
2) Then we measure all 12 parts with CMM. As measured points, we have 500 points in each part. (we have the CAD model. This means that for all points we have the nominal value.)
The question is:
How to calculate the capability of each machine?
How to compare the machine's performances?
Thanks in advance for your help.
