Design of Experiments a Technique that Compares Quality in Terms of Variation - A Case Study of Process Capability Improvement of a Manufacturing Process

Onkar Pathak

This case study is based on the improvement of the quality of the adjustment screws by improving the process capability and process capability index of the boring operation using DOE. For the better quality, Cpk of the process should be a minimum of 1.33. The objective of this case study is to deal with the measurement of variation in the manufacturing process and introduce Cp and Cpk as parameters that compare the quality and measure the variation in the process. Also, it identifies the important variables whether they be process parameters, materials, products, and further, separates these variables, and reduces the variation of the important variables using differential diagnosis techniques. This approach helps to study and analyze the effect of variables and the effect of their interaction. Also, this approach tightens the effect of interaction through process improvement using Design of Experiments (DOE).
