Surface Workhardening and Residual Stresses Induced by Micro Cutting Processes
X-ray diffraction, optical microscopy and microhardness testing have been used to study properties which develop in micro-cut AISI 1045 steel. The influence of the ploughing effect on residual stresses, surface deformation and work hardening, and the tool quality were investigated. Tensile residual stresses, caused by the heat generated in the material during the cutting process, were observed ...

متن کاملInfluence of Rake Angle and Hardness Ratio on the Formation of Discontinuous Chip during Orthogonal Metal Cutting
In the present investigation, numerical models that accurately predict the chip formation and stress profiles in the work-piece during orthogonal metal cutting were developed using the explicit finite-element method (FEM). More specifically, a damage material model was utilized to capture the work-piece chip formation and simultaneous breakage of the chip into multiple fragments. In the simulat...
متن کاملInfluence of Cutting Edge Shape on Residual Stresses of Cut Surface* (Effects of Nose Radius and Cutting Edge Roundness)
In order to obtain basic information on the improving the surface integrity of machined surfaces, the relationship between the residual stress of cut surfaces and the cutting edge shapes of cutting tools was examined. Dry facing on a lathe was performed with cutting tools that had various nose radiuses and cutting edge roundnesses. The residual stresses of the cut surfaces were measured by X-ra...
