Using DOE for Implementation of Six Sigma to Reduce Non-Coaxiality Defect in Connecting Rods

Abstract:

This paper is intended to determine all significant factors affecting one of the most important characteristic of connecting rod that is coaxiality, in one of the main suppliers of this part in Middle East, in order to achieve the optimum combination and levels of these factors. By sampling the connecting rods produced under different levels of factors and combinations, and measurement of non-coaxiality, enough data is gathered. To determine meaningful impact of each intended factor and to specify all effective and ineffective factors, the authors have used DOE method. Achievement of best combination consists of affecting factors is defined through DMAIC cycle steps to reduce the non-coaxiality defect and to reach intended sigma values for the production process. According to the analysis of the results, better rate of non-coaxiality is obtained.
