A Study on Minimising Rejection in a Model Grinding Cell

Zero defect management is an idea that gained its focus from 1960's. The philosophy was put together and proposed by Philip Crosby. It is a program to eliminate defects in industrial production, and was primarily intended for automobile production. Manufacturing processes tend to produce operational wastages due to various reasons, which can be reduced by identifying and eliminating those reasons. It has been a very challenging engineering problem particularly in multistage manufacturing, where maximum number of processes and activities are performed. The objective of this paper is to identify issues in model grinding cell and provide suggestions to achieve Zero Defects in Model Grinding Cell. The study was conducted in a manufacturing company. Primary data was collected by observation. Analysis was conducted for finding root cause using fishbone diagram. Suggestions were provided to achieve Zero Defects with the help of Pareto Analysis Diagram. With the help of Pareto diagrams, which are mostly used to identify critical areas, the manufacturing process defects in each stage of production have been prioritized by arranging them in decreasing order of importance. Then cause and effect diagram was applied to explore the possible causes/factors of defects and to determine the causes/factors, which has the greatest effect.
