Ultrasonic milling is a hybrid machining process combining the material removal mechanisms of ultrasonic machining and milling,which has been cost-effective machining method for hard and brittle materials.It is difficult get the steady vibrational state which the tool in the ultrasonic frequency range,so it make the best of the energy when the ultrasonic vibration is loaded.The result of modal analysis for the tool of the ultrasonic vibration milling is calculated with ANSYS Workbench,it obtained the natural frequencies and modal shapes.By comparing find out the natural frequency and change the size of the tool holder,so that the inherent frequency comfort to the design requirements.

In order to resolve the problem of data acquisition and real-time display in the design of CNC system,based on introducing the method of PMAC data acquisition,the theory of communication between Win32 applications and PMAC was highlighted.The method of PMAC data acquisition and real-time display under the environment of Visual C+ + was introduced.A satisfactory result is achieved by applying this technology to the development of CNC system of wire cutting.

To solve the difficult and low-efficient processing problems of slender inner helical surface, the layered processing theory and method of slender inner helical surface based on slender inner helical surface structure in screw drill stator as the research object is put forward. The whole processing of slender inner helical surface is innovated by simple layer processing, which reduce the processing difficulty and improve manufacturing efficiency. The key techniques are studied such as screw drill stator structure, the design method and processing technology and the analysis and calculation of interference, which provide the theory for layered processing of slender inner helical surface structural components processing.
