I am a QE for a large manufacture of precision forged gear for power transmission in heavy duty trucks and am trying to establish capibility on a chage from vetrified honing stones to ceramic stones. The problem I am having is that the machine automaticly compensates 1 micron between every part for wheel wear and dresses the stone every 10 parts and then compensates for the dressing. This makes it impossible or at least that I can see to reach our required 1.67 Cpk. Is there a different type of study one should do for this sort of operation? Any help or suggestions will be appericated. My background i many years in mechinical engineering and only a short while in Quality Engineering.
