2205 振動切削を利用した 6 軸制御加工・オーバハングした角隅形状の場合

Abstract

The study proposes a new machining method to create a sharp corner on over-hanged surfaces. Sharp corner on overhanging surfaces are difficult to machine in conventional way or even in 3 to 5-axis EDM machine especially if the surfaces have different angles. In present research, we try to machine the sharp corner using the new machining method. The 6-axis controlled machining using the non-rotational tool with the application of ultrasonic vibration has been applied, since they can set the non-rotational tool in an arbitrary position against the workpiece. From the experimental results, it shows that the 6-axis controlled ultrasonic vibration cutting is capable of producing a sharp corner on overhanging surfaces.
