Abstract

The quality department faces the problem of “Grease Missing in Inner Ball Joint Assembly” of manual steering gear. The objective of this system is to improve the overall productivity and to eliminate the defects without compromising the quality, optimizing the cost and time of the defective components. The problem is identified by Pareto Analysis which is one of the techniques of six sigma. The problem is analysed by various quality control tools such as Affinity diagram, Relationship diagram, Multi-vari chart, Why-Why analysis, signal-to-noise ratio analysis. The signalto- noise ratio analysis (Taguchi Method) helps to find the most significant factors for the problem. They are re-designed to overcome the problem and gives the counter measures for the problem. This counter measure is suggested to the company which has forwarded to the quality department. The suggestions are given to the company and the expected results are achieved.

Keywords
