Abstract

Six sigma is a quality improvement methodology. In this research paper, six sigma methodology is used for end shield FG 200 Grey casting of electric body. DEMAIC methodology along with Taguchi method is used to minimize the defect in end shield casting. DOE and analysis for variance techniques are used to determine the correlation of defects with the pouring temperature, pouring time and Si percentage and their optimum values are found out to reduce the defects. Finally, microstructure analysis is carried out as per ASTM A247 standard using Pro metal 3.3.1 image analysis software.
