Abstract:Modeling and simulation of the metal cutting processes have the potential for improving cutting tool designs and selecting optimum conditions. A FEA (finite element analysis) model to simulate the cutting process in turning and predicted cutting forces, tool stresses and temperatures was developed using finite element analysis. Using FEA software Deform, previously developed flow stress data of the workpiece and friction coefficient were used. As an application, machining of 45# steel at 200 HB hardness using uncoated carbide tooling was investigated. The predicted forces in orthogonal turning process show similar trends and reasonable agreements when compared with experimental forces. The highest temperature was predicted at the rake face (around the prime cutting edge) of the tool regardless of cutting conditions. The highest tool stress was predicted at the rake face (around the prime cutting edge) of the tool.
