Computer Modeling Application for Predicting of the Passing of the High-Speed Milling Machining Hardened Steel

A high-speed milling of hardened steels at multi-coordinate machining centers in individual and small-series production has become of special interest because of the ability to provide high-quality characteristics of products. To ensure the surface layer quality with extremely small values of residual roughness, surface microhardness, and structural phase composition, a computer-aided simulation of the high-speed milling process by computational-logical algorithms based on the finite element method was performed. The experiments with computer simulation research of high-speed milling were done for two objectives: the process of rectangular cutting and the process of oblique-angled cutting of materials. Two-dimensional and three-dimensional computer modeling was used for the research. The connection between the chip formation process, the stress-strain state of the material, and the angle of inclination of the chip-forming groove of the end mill was established. The maximum value of the energy contribution to the cutting process was offered to choose for the determination of the maximum limit cutting conditions in high-speed milling.
