This paper describes the investigation of cutting forces in milling, according to the properties of steel group C10-C60. The measurement of cutting forces is one of the most frequently used techniques for the monitoring of machining processes. Analytical model and numerical models are used to determine the cutting forces. In analytical model and numerical model cutting tool moves in translational movement and rotational movement. Two types of numerical analysis was chosen: the numerical model a validity test and definition of cutting forces according to the steel material group C10-C60. 3D numerical FEM-SPH modelling is performed by using commercial software LS-DynaV7. A 3D finite element model is created by taking an account of workpiece dimensions and cutting tool. Workpiece material cross-section of given depth is removed during milling process. The inputs of the model consists of feed, cutting speed, depth of cut and physical and mechanical charecterisics of workpiece material. After running the simulation program in LS-dyna, cutting force values are obtained. The numerical results were compared with analytical results. |
