Mechanical Characteristics Generation in the Workpiece Subsurface Layers through Cutting

The cutting process generates specific mechanical characteristics in the subsurface layers of shaped parts. These have a decisive influence on working properties and product durability these orthogonal structural heat-treated steel’s effect machined was evaluated by instrumented nanoindentation method sclerometry (scratch) method. As result this study, relationship between work tertiary zone total deformation during indenter penetration established. dependence depth workpiece also studied. carried out at different speeds tool rake angles. speed increase angle cause an maximum sclerometry. Simultaneously, measured microhardness surfaces decreases with both angle.
