Impacts of Surface Texture and Nature of Friction on Energy-Force Efficiency of Surface Plastic Deformation during Burnishing

Burnishing, the plastic deformation of workpiece surface due to sliding contact with a tool called burnisher, is finishing operation widely used in various industries. In this work, impacts initial roughness Ra being burnished, nature friction zone, and clamping force on stability energy efficiency burnishing have been investigated. Experiments conducted without lubricant, represented by low-viscosity deep-hydrogenated fraction sour oils, at 0.8 1.25 ?m variable (100–200 N) force. A key process indicator, which largely controls mechanics burnishing, temperature tool-workpiece zone has measured using natural thermocouple method. Microhardness after also measured. It shown that changes are proportional squared This dependence appeared be universal equally applicable lubrication. Based analysis experimental data, new criterion developed. The simplifies choice optimum operational parameters helps preventing adverse structural phase transformations layer unavoidably lead reduced product quality reliability reducing wear, critically important case dry burnishing. obtained results show accompanying significant impact process. While for lubrication, an only. Application minimum quantity lubrication (MQL) under conditions typical industrial found favorable. particular, it was MQL not only enhances but increases its more than 20%.
