Abstract

In metal production mechanical surface treatments are used to optimize workpiece characteristics like fatigue strength. Complementary Machining is a new machining strategy which is characterized by the combination of cutting and mechanical surface treatment. After cutting the insert is used reversely acting as a tool for mechanical surface treatment. This paper shows the effect of high plastic deformation rates in the surface layer reducing surface roughness and increasing strain hardening. Furthermore, it is supposed that the process induces grain refinement in the surface layer. The process strategy Complementary Machining is investigated during machining Armco-Iron and AISI 4140.
