Abstract

A two-dimensional numerical technique has been adopted to study the temperature rise, chip morphology, plastic stress/strain, strain hardening, and softening effect on the selected steel grades, namely S-1006, S-7, and S-4340 in the planing process. The material properties and constants are instituted on the popular Johnson–Cook (JC) constitutive model. A comparative analysis has shown, the maximum temperature rises in the case of S-7 (641.32 °C) followed by S-4340 (478.96 °C) S-1006 (287.19 °C). The temperature rise is mainly found in the secondary shear deformation zone and rise in shear stress found in the primary deformation zone. The plastic deformation is found facile in the case of S-1006 anticipated due to less dislocation within the crystal structure and work hardening effect found to be maximum in case of S-7 and the same is confirmed from the JC model material constants. It is believed that the simulation results may help in predicting machining uncertainties.
