Influence of increased die surface roughness on the product quality in rotary swaging

Abstract. Rotary swaging is an ascendant forming method for manufacturing axisymmetric parts. High production rate with excellent net shape achieved in recent automation developments. However, precise machine design and tailored process developments are necessary to transfer the high impact type loads workpiece efficiently. The failure of this results vibrations structure poor product quality, due frequencies. centerpiece development prevent these disruptive effects resolve die specifications such as surface properties. In general applications, roughness dies perceived a element quality only small amount provided settle lubricants. rotary optimized increase load between without disrupting final essential. study, fixed shape, relation investigated macro applications. particular, effective forces analyzed by using finite analysis within scope friction. Consequently, set roughened conditions manufactured novel technique. Real trials conducted validate analysis.
