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 3D FEM simulation results performed for the power law and JC (Johnson-Cook) material constitutive models for two sets of friction parameters. The friction conditions were tested using pin-on-disc tribometer. Machining tests were carried out using carbide cutting tools coated with a TiAlN monolayer without coolants. The selection of machining conditions was based on real production data. In addition, a real CAD model of the cutting tool insert was implemented. Moreover, an advanced technique of meshing the cutting edge and the grooved rake face was applied. The simulations include cutting forces and cutting temperature. Finally, FEM simulations were compared with measurements in order to improve the simulation strategy.

Opis:: This paper presents 3D FEM simulation results obtained for the milling operations on a nickel-chromium alloy (Inconel 718) using the Johnson-Cook material constitutive model and variable cutting conditions. Face milling tests were carried out using silicon-aluminum-oxygen-nitrogen (SiAlON) ceramic cutting tools inserts. The machining conditions were selected based on real production data (cutting speed of vc=750 and 800 m/min, feed of f=0.1, 0.125 and 0.15 mm/t, depth of cut of ap=1, 1.5 and 2 mm). The FEM simulations include the maximum and average values of the cutting temperature. They were compared with experimental data obtained by using the high speed infra-red camera.

Inconel 718
Opis:: This paper is focused on the finite element analysis of machining of Inconel 718 superalloy in a non-orthogonal (3D) turning process. The cutting experiments were carried out on the cylindrical workpiece of Inconel 718 with the cutting speed of 60-90 m/min, the feed rate of 0.1 mm/rev and different depths of cut. The FEM simulations include the average and maximum interface temperatures, the resultant cutting force and its three components and the chip thickness obtained for the 3D turning process. The simulation results were compared with experimental data obtained in the non-orthogonal process. It was found that the experimental values of the cutting forces are underestimated (about 23-30%) in relation to the FEM simulation data. Additionally, it was noted that the cutting depth has a significant effect on the average interface temperature only when using a non-orthogonal turning process.
