Optimal Manufacturing Cost and Quality Loss by Reciprocal Exponential Cost-Tolerance Function

Abstract:

Specific improvement of a quality of the product and its productivity improvement mainly depend on the designing and fixing of the tolerance of that product. This is done prior to the design stage of the product. Design of tolerance is based on its functional conditions only then its specification for each component in a mechanical system is developed. The finalized tolerance is printed as a drawing (blue print tolerance), inclusive of individual part details, fit and function parameter, critical parameter and design criteria.This paper reveals a new comprehensive and analytical method for fixing an optimal tolerance by worse case limit. This is done to reduce the manufacturing cost and to improve the quality loss of the product by using the expoentional cost function. An example illustrates the proposed model attached with solution method.
