The computerize numerical control (CNC) system is one of the key factors for the development of micro v-groove machine tools to fabrication micro v-groove structures. Based on the investigation on the machining of micro v-groove structures, a developed software contains five modules: editing, automatic programming, program control, manual control and human machine interface. A3200 software based motion controller integrated with the machine characteristics is used in this study to develop the motion control functions of the micro v-groove machine tool. Meanwhile, a method is proposed to redefine the instructions of M, T and S by setting monitoring points so as to enhance the scalability of CNC system. The results show that the CNC system software is not only stable and reliable, but also satisfies the basic requirements of the ultra-precision machining of micro v-groove structures.

In order to use magnetorheological finishing (MRF) to accomplish ultra-precision machining of complex curve surfaces, an open computer numerical control (CNC) system based on universal motion and automation controller (UMAC) has been developed. The paper introduces the hardware structure of the system, elucidates the control algorithm and parameters tuning of PID + velocity/acceleration feed-forward + notch filter, and explains the design of a friendly human-machine interface (HMI) to satisfy the need of actual manufacturing and complicated numerical control. With the open CNC system, a 4mm-diameter circle is polished on the MRF experimental prototype with the contour error of 1.67% and the surface roughness Ra of 1.4nm. Experimental results prove that the open CNC system for the MRF machine tool meets the requirements of ultra-precision machining.

With the development of modern manufacturing, it is obvious that traditional numerical control system is bad in compatibility and is expanded uneasily in function and is not flexible in human-machine interface. The open numerical control system has become the research mainstream of numerical control technology. Therefore, the open motion controller based on PC is developed in the paper. In addition, the components and design method of system are introduced in detail.

In order to improve chemical mechanical polishing (CMP) efficiency and accuracy in the fabrication of planar optics, CMP models and machine tools have been developed. A three-dimensional contour map of the surface of the polishing plate was established by measuring the runout error of several circles on the polishing plate. Based on the Preston equation and the three-dimensional contour map, a CMP model that simulates material removal at any point on the work piece is proposed. This model shows that higher motion accuracy can improve efficiency and accuracy. Then, based on this point of view, a new CMP machine tool was designed, and the ultra-precision gas static pressure guide rail and turntable and Siemens 840Dsl numerical control system were applied to the new CMP machine tool. In order to validate the new machine, a series of testing and processing experiments were carried out. The straightness error of the gas static pressure guide rail can be less than 1.1 μm. The axial runout error of the gas turntable can be less than ±0.4 μm. The surface profile of the experimental workpiece can be less than 0.01λ, and the processing efficiency of the new CMP machine can reach 4 times of the processing efficiency of the conventional CMP machine. In addition, the repeatability and stability of the CMP process is improved on new machines.
