Abstract

The process variables i.e. the speed of forming, the ratio of thickness to diameter the shape of formed materials and the reduction of area were selected in order to study the process of the rotary swaging. It was found that the process variables affected the quality of products, i.e. the hardness the surface roughness and the degree of precision of products. Variation of hardness in deformed samples was mainly dependent on the reduction of area. Upon forming tubes applying the t/D ration higher than 1/10 led to the formation of defects on products which may be reduced by application of mandrels.
