Ultrasonic machining progressive development in recent decades and application of a new processing method

Ultrasonic machining is the progressive development and application in recent decades, a new processing method, not only can be processed carbide, hardened steel and other hard and brittle metal material, and is more suitable for the semiconductor and non-conductive non-metallic brittle materials (such as diamond , semiconductor silicon, germanium films and ceramics, glass, etc.). use of ultrasonic vibration processing method for processing polycrystalline diamond wire drawing die has been recognized by domestic and foreign experts and scholars, in the process to the tool along with regular, controlled ultrasonic frequency vibration, thus driving the abrasive slurry material to be processed surface of the impact, so as to achieve the purpose of removing material, the effect of ultrasonic machining tools and depends largely on the merits of the relative trajectory drawing die is reasonable in the processing tool during the machining surface should be uniform processing path and achieve good coverage. trajectory of processing and computer simulation on the basis of the processing parameters can be optimized to improve processing efficiency and facilitate the rational use of processing equipment, for mechanical further optimization of the structure to provide effective guidance.
