Decision Method of Statistical-Tolerance-Indices Considering Product Performance(Digital design and digital manufacturing)

Abstract

The purpose of this paper is to show a method of a performance design using statistical tolerance indices. Firstly, the sum of statistical tolerance of parts is studied. Then a decision method of statistical tolerance indices is proposed, and the proposed method is demonstrated in case study. Simultaneously, the proper condition for performance improvement using statistical tolerance index C_<pm> is shown.
