A study on the process capability of machining process
Hwan Tae Sung
The research on the process capability is the basis for quality design, operation standard and so on. In this study, histogram of the measured value for the cutting process and calculation of the capability factor Cp are established, resulting in the classification of 4 grades, and necessary measures for them are presented. The advancement of productivity is the most significant result of this study. The processing time per piece for those stabilized processes having the capability factor 1.33 and above is lessened, and the advancement in quantity capability is made possible permitting dispersion of standard up to the tolerance limit. The exact knowledge of process capability is most important for the quality design system. For the efficient application of this result of the research, a systematic and positive cooperation by the whole company members is needed.
