Laser-assisted machining (LAM) is a new hybrid method and widely used in various difficult to machine materials as it improves the productivity (reduces energy efficiency) and surface quality. In LAM, machining in the workpiece is carried after reaching the preheating temperature using a laser. Among the various difficult-to-cut materials, Inconel 718, nickel-based super alloys, is difficult to machine due high strength at elevated temperature and low thermal conductivity. In the present study, the effect of machining conditions on cutting forces, cutting temperature, stress, has been studied using finite element modeling in laser assisted machining operation of Inconel 718. Three values of cutting speed are taken (50, 75 and 100 m/min). Cutting force, feed force, stress, and cutting temperature is predicted using commercial Abaqus/CAE at different machining conditions in laser heated conditions. With the increase of cutting speed in laser-assisted machining conditions the cutting force and feed force increased. In order to validate the numerical results an experimental analysis is performed and a result in good agreement between them is observed. © 2017 Elsevier Ltd. All rights reserved.
