Abstract

Process capability indices can be viewed as convenient and excellent tools to measure and define process output. Several capability indices including C p , C pu , C pl , C pk , C pm and C pp have been widely used in manufacturing industry to provide common quantitative measures on process potentials and performance. Process capability inex C pp can be used to measure product capability with respect to process targeting. “The larger the better” is the general rule for the application of process capability indices C p , C pu , C pl , C pk and C pm . However, those researchers take accounts for processes with single quality characteristics only and cannot be applied to a product family with different models, types or sizes simultaneously. the approach of this paper is to propose a concise and applicable methodology that measures the entire process capability of a product family with several models. For convenient and practical application to product engineers, a simple procedure of hypothesis test for entire process capability of a PVC pipe product familiy is well established.
