Abstract

Quality of conformance is  defined as the degree to which a product or  service conforms to its design specifications. In this paper. random assembly  products are considered. and the degree of conformity of a random assembly is  defined as the probability that the assembly will meet Its specified  tolerance . Furthermore, Models of inequalities are formulated to show the  relationships between assembly total tolerances, individual part tolerances,  and assembly degree of conformity for a random assembly consisting of two or  more parts (components). These inequalities can serve as a tool to set up  parts dimensional tolerances and/or assembly dimensional tolerances so that a  predetermined assembly degree of conformity is met, and vise versa .
