The aim of this study is to create a FEM simulation model in order to obtain Numericalsolutions of cutting forces, for a range of coated tool materials and defined cuttingconditions. Commercial implicit finite element code MSC.Marc has been used insimulations of orthogonal cutting processes performed by means of multi-coated tools. Thelatter were equipped with progressively increasing number of thin layers including TiC, TiNand Al2O3 films deposited onto ISO P20 carbide substrates. Results showing the tool–chipinterfacial friction influencing the force distribution fields, as the consequence of usingcoated tools. The various force simulation results obtained were compared with themeasurements of cutting force and discussed in terms of literature data.This paper also reports the procedure and specific modeling techniques for simulatingthe orthogonal metal cutting process using a general-purpose finite element computer code.The finding of this paper provides useful insights for understanding and for improving theorthogonal metal cutting process. The predicted value of Fc is in good agrement with theexperimentally measured with an error of 8%
