During the turning process of metastable austenitic steels, austenite is transformed into hard martensite by plastic deformation at low temperatures. This enables production components, which have both a hardened subsurface zone and ductile core. Cryogenic cooling allows to be during machining, leads shortening chain. However, effects such as wear can make it challenging adjust properties turni...

Abstract The abundant use of cutting fluids in surface grinding process and the corresponding costs energy consumption have been a major sustainability concern. This paper identified optimum depth cut for under controlled parameters using compressed air cooling technique dry cutting. morphology subsurface defects workpiece material (AISI 304 stainless steel) were measured compared. It was obser...

Marking of metal products is essential in many industrial processes. It mandatory for the finished according to regulations European and world legislation. Traditional marking usually creates contrasting symbols that can easily be erased forged.In recent years, a new method product identification has appeared - color marking. One advantages this it difficult counterfeit. This article aims prese...
