IMPLEMENTATION OF DMAIC METHODOLOGY TO CASTING INDUSTRY

Abstract

SIX SIGMA approach is a business strategy used to improve business profitability and efficiency of all operation to meet
customer needs and expectations. In the present research work, an attempt has been made to apply DMAIC (Define,
Measure, analysis, improve, control) approach. The emphasis was laid down towards reduction in the defects (Blow holes,
metal spread out, Surface cracks, uneven metal layer thickness) occurred in the castings by controlling the parameters
with DMAIC technique. The results achieved show that the rejection due to defects has been reduced from 31.703% to
12.82%.
