Experimental investigation on cycle time in machining of
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 A crankshaft is a mechanical component used in a piston engine to convert the reciprocating motion into rotational motion. The crankshaft is a rotating shaft containing one or more crankpins, that are driven by the pistons via the connecting rods. The crankpins are also called rod bearing journals, and they rotate within the "big end" of the connecting rods. Crankshaft

Crankshaft Grinding: A Comprehensive Guide for Engine Enthusiasts
Crankshaft grinding is a process used to repair or enhance the performance of an engine’s crankshaft.The crankshaft is a vital component that converts the reciprocating motion of the pistons into rotational motion. Over time, the crankshaft may develop wear, damage, or misalignment, leading to decreased engine performance and potential failure.To minimize the machining of the crankshaft balance and the shortest machining time, the gradient hole method can be used to calculate the center hole position[5].

Manufacturing processes’ role over the residual stress state
1 Introduction. A crankshaft can follow several manufacturing routes. Forged or casted, heat-treated or deep rolled, the selection of these variations depends on general design requirements. Each individual process will imprint a different residual stress (RS) state in the component, which can be negligible or not.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%.Experimental investigation on cycle time in machining of forged crankshaft
