A thermo-elasto-viscoplastic two-dimensional finite element analysis of the effects of different edge radii on the mechanics of orthogonal metal cutting is presented. The shear stress distribution was used to quantify the stagnation point as well as the minimum chip thickness needed to form a chip when using a honed cutting edge. The determined location of the stagnation point using the shear stress distribution agrees well with location calculated using the velocity profile in the vicinity of the cutting edge. The plastic flow of the material around the honed cutting edge and below the machined surface was studied. The ploughing force generated while cutting with a carbide tool was calculated. Contour plots of stress, strain, temperature, and velocity in the cutting zone were analysed along with contact stresses and temperature profiles on the rake face.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
