Method for optimum calculus of machining parameters according to tool trajectories type based on milling process simulation

Abstract

Virtual manufacturing systems can provide useful means for products to be manufactured without the need of physical testing on the shop floor. As a result, the time and cost of part production can be decreased. The paper presents the influence of tool path trajectory on surface deviation geometry when finishing inclined surfaces. The aim of the study is to optimize the milling process taking into account the milling strategy. The research was focused on ball end finishing because it is well known that in plain cutting, in the centre of the flat mill the cutting speed is vc = 0 m/min. According to that, the surface roughness is influenced by the fact that in this area a friction process occurs and not a cutting process. Six types of tool trajectories were simulated and surface deviation was evaluated.
