Application of Taguchi Technique in Gas Cutting Process - A Case Study

This paper offers a different view of quality that has traditionally been used. Uniformity of products is of greater concern than just conformance to specifications. Improvement in quality by reducing the number of defectives is a goal every organization likes to pursue. However, the reduction of defectives requires an additional investment in procuring suitable technology and training of employees. Small scale industries with their resource crunch are at disadvantage because of this. Taguchi is a simplified way to overcome this problem. This work includes a detailed description of taguchi methodology. The statistical tool for the analysis of the analysis of the data (ANOVA) and the concept of orthogonal array are also dealt with. An attempt has been made to implement the 16-step methodology of taguchi in gas cutting. The results and verification of those results using Qualitek-4 software are also presented.
