Abstract

Problem solving plays a major role in quality engineering and it is popularly adopted by manufacturing industry. This study is aimed to determine root cause for rejection of cylinder head due to rough conical grinding problem by Shainin method. This has two major parts, first is diagnostic part which involves finding out the root cause and second is a remedial action part which consist of actual application of findings to rule out the problem. Wear in tool holder assembly is identified as root cause for rough grinding problem. Converging to root cause and validating the same achieved by successful implementation of Shainin tools.

Highlights

  • IntroductionTo generate the pressure demanded by common rail system (CRS) it is necessary to produce components of pump with highest quality .Problem solving comes under lean efforts taken by organization [1]

Summary

Introduction

To generate the pressure demanded by CRS it is necessary to produce components of pump with highest quality .Problem solving comes under lean efforts taken by organization [1]. It plays a major role in both ways to improve quality and reduce the rejections and losses [2]. Shainin is convergent method of problem solving, involves continuously keep on eliminating the variables to converge to the most influencing variable [3]. Shainin methodology based on identifying contrast between good and bad pats, that’s why it is simple and fast [4]. It makes use of specific tools to converge to the root cause quickly [5]
