Hello everyone,
I'm new to this website and have benefited from reviews many times.
I would like to describe a problem I encountered with an MSA Study Type 1.
The Cg / Cgk value of the MSA Study Type 1 is less than 1.33. But the production process must also be continued. Manufacturing engineers came to me with two suggestions.
1-Is it allowed to continue using the measuring process with a tolerance reduction (from 5 mu to 4 mu)?
Or
2-In this proposal, instead of individual measurements (for example 25 individual measurements), two or three measurements are taken each time and their mean value is evaluated as one measured value (for example, 25 measured values are obtained from 3 x 25 measurements).
I rejected the first proposal. Because I know that will increase the risks. On the other hand, instead of reducing the tolerance, I recommended an increase in tolerance.
I am also aware that the second suggestion will decrease the standard deviation and thereby improve the Cg / Cgk value.
Is the second suggestion allowed? And should we repeat MSA Study Type 1 according to the proposed solution (two or three measurements taken each time and their mean value evaluated as a measured value)?
I would be very happy if you can enlighten me.
