A Study on Hot Forging Process of the Motorcycle Connecting Rod to Ensure the Quality and Effectiveness of Products Applying the Digital Simulation

In this study, a hot forging process of the motorcycle Connecting Rod was performed from workpiece processing to the cutting process to achieve the final products. Starting from the cylindrical workpieces, the workpieces were processed by turning and upsetting methods. Applying the Finite Element Method (FEM), a series of forging processes were conducted using QFORM.10.1.6 to evaluate the quality and effectiveness of the forging process including maximum forging load, ability, detection of the laps, processing time, material cost, etc. By evaluating the quality and effectiveness of each forging simulation, the best solution was determined with quality requirements and saving the processing time and workpiece material by 31.48% and 24.66%, respectively.
