Opis:: In this paper parameters of the Johnson-Cook (J-C) constitutive material model were predicted more accurately based on the static and dynamic material tests and mathematical modelling of relevant response surfaces using specially developed Matlab scripts. Experimental tests were performed under strain rates of 10^-3 and 10¹ 1/s and the temperature ranging from the ambient up to 700°C. As a result, a set of mathematical models which fit the experimental data was determined. The experimentally-derived constitutive models were implemented into FEM-based simulations of real machining processes of Inconel 718.

Opis:: This paper presents experimental and 3D FEM simulation results obtained for the Johnson-Cook material constitutive model and variable cutting conditions. Face milling tests were carried out using a Ti6Al4V titanium alloy as the workpiece and coated carbide indexable inserts. CAD models of the cutting tool insert and the face milling head were generated and implemented into FEM package used. The machining conditions were selected based on real production data from aerospace sector. In particular, changes of power and specific cutting energy were analyzed in terms of the rotation angle of the milling head and the ratio of the uncut chip thickness against the cutting edge radius.
