| Popis: | Ultrasonic vibration assisted turning (UAT) is a machining method for creating precision surfaces that because of advantages such as increased tool life, decreased cutting force, high surface quality, and increasing the machinability of hard cutting materials is widely used. In this method, optimal choice of machining parameters has a significant effect on the obtained surface texture. This paper examines the parameters that influence surface texture in the UAT. Therefore, an algorithm was provided to simulate surface textures in the process of ultrasonic vibration assisted face-turning in three modes of one-dimensional, two-dimensional and three-dimensional. To validate this algorithm, experimental tests were performed on Al7075-T6. Comparing the results of the algorithm and experimental tests shows that the surface texture resulted from simulation algorithm is well-matched with the results of experimental tests. Finally, the effect of machining parameters of cutting speed and feed rate are investigated in a variety of vibration modes applied to the tool.
