Accuracy and topography analysis of hard machined surfaces

Research on efficient machining of hardened surfaces is invariably interest because the number wear resistant machined parts increasing. These can be by both single-point (cutting) and abrasive (grinding) tools. However, in designating finishing parts, working characteristics products that are intended for limit options. In this paper results a comparative experiment introduced. experiments allowances were removed from turning, grinding or combina-tion them. The analyses carried out roughness accuracy ma-chined procedures assessed.
