AUTOMATION IN MANUFACTURING OPERATION OF CRANKSHAFT

摘要

This paper deals with multistage flow type manufacturing of crankshafts. The advanced methodologies in manufacturing systems, re-configurability and high speed manufacturing adopted in the paper will help reduce cost and improve productivity. The optimization of the multistage manufacturing is based on mathematical programming formulation and decomposition approach. The optimum process parameters such as speed, feed and depth of cut for individual operations are calculated using this technique. The effect of change in design data on manufacturing parameters and eventually the cost of the crankshaft at each operation are visualized. This is likely to help the manufacturing engineers to attempt to reduce cost at appropriate stage. The manufacturing automation of crankshaft is attempted on the methodology presented in the paper. The final configuration of the automated production system shows the specification of machine tools in the production system.
