Abstract

This paper presents the reliability of the Taguchi Method for improving the product and process quality in the industrial environment. The purpose is to signify the applicability of the Taguchi method in process optimization. The application of the Taguchi design of experiment (DOE) is widely reported and published but the success of the Taguchi method as a prominent tool in solving the industrial problem is not disclosed. In this study, the shot blasting process was chosen with two control factors of blasting speed and turntable speed; both factors were set at three levels. The rotor blasting speed and turntable speed were set between 2500-2900 rpm and 35-45 rpm respectively. From the result obtained, it was found that the surface roughness capability index improved from Cpk -0.14 to 1.06, i.e. an improvement in the S/N ratio of 113% (from 12.78 dB to 27.21 dB). The main factor that significantly affected the surface roughness variation was rotor blasting speed which contributed 56.9% of the total effects. The optimum setting was by setting the rotor blasting speed at 2900 RPM and the turntable speed at 39 RPM. The estimated tolerance setting was found to be 1% and 2% for the rotor blasting speed and turntable speed respectively. The optimum setting resulted in the improvement of the surface roughness, i.e. the quality of the part. Taguchi method is an effective way to determine optimum performance through the analysis of optimum combination parameter setting.
