| Abstract | ||
| This research presents the theoretical model, simulation and experimental verification to predict the magnitude of scallop height using 3 and 5-axis milling machine, where the effect of geometrical shape of the workpiece relative to the effect of geometrical shape of the tools had been studied, taking into consideration three different types of milling tools (Ball, Flat and Torus) corresponding to the type of machines that had been used to calculate the scallop height (h) in each point. Also, four different types of surfaces shape (Horizontal, Concave, Inclined and Convex) surface had been utilized to study the effect of these shapes on the value of scallop height. Besides, the effect of cutting direction in each plane had been studied in both types of milling operation (three and five axis milling machine). Finally, the value of stepover had been changed so as to acquaint the effect of this parameter on the magnitude of scallop height on both types of milling operation. It was established that the scallop height is most influenced by the step over, cutting direction, geometrical shape of the cutter and inclination angle of the plane. The results also show that in 5-axis machining by utilizing different cutters, the angle of inclination of the tool axis was most affects the value of scallop height. It was also concluded that Torus cutter is better than other two cutters (Ball and Flat end mill cutters). | ||
