摘要：

The study performs the analysis of existing technological schemes of manufacturing crankshaft forgings. Advanced technology of the manufacturing is proposed based on this analysis. The influence of sizes of a tool and its indentation depth on the forming process of a workpiece is examined. As a result of the carried-out theoretical and experimental studies, dependency diagrams of the influence of the upper die thickness and its indentation depth on the change in sizes of the workpiece, namely the maximal widening, the lengths of the contact areas of the workpiece with the upper and lower dies and the value of the maximal workpiece diameter reduction is received. These diagrams can be used to determine optimal parameters of the process of the narrow die indentation into a workpiece to receive the optimal form of the workpiece, used for the subsequent forging. The comparison of the results of the experimental studies and computer simulation in the QForm V8 program showed appropriate convergence of the results.
