Experimental investigation on cycle time in machining of forged crankshaft

2021年1月1日  It observed that machining time was more on two machining operations specifically in rough turning and grinding. Initial cycle time was 92.73 min for processing of crankshaft. After modifications, cycle time is reduced 88.63 min. It is found that machining cycle time is reduced by 4.1 min. This results in the improvement of cycle time by 4.42%.
