In view of application requirements, control axes, the development cycle and other factors of open CNC machine tools, we consider the modular as the guiding ideology and propose a design method of three-dimensional engraving and milling machine based on open CNC system. In this paper we make a detailed design for mechanism structure and control system. Experiments show that this machine has milling and engraving capabilities, can process metal and non-metallic parts, which is a high efficiency, multi-function numerical control equipment.

The characteristics of open CNC system and the current several open CNC system models are introduced in this paper. In order to overcome the contradiction between the frequent changes demand and the closure of the traditional system, the open CNC system software and hardware architectures were investigated based on web-collaborative design and development, which improve the system development efficiency. Using the Windows XP operating system as a software platform, the Visual C++ 6.0 object-oriented programming language is adopted to design the CNC drilling control software based on the "PC + NC" the model and modular co-design methods, which improve the openness of the CNC system.

In order to find and repair surface damage on KDP crystal, an open computer numerical control(CNC) system has been developed. This paper introduces the hardware structure of the control system, explains the development of an open CNC system software, which has friendly human-machine interface (HMI) and can make the finding and repairing process efficiently and conveniently and also expounds the algorithm and related parameters for servo tuning. With the open CNC system, the process of finding surface damage is accomplished in 3 hours and clear images of crystal surface damage is taken by CCD. And also, with the help of the open CNC system, a 600µm-diameter, 25µm-depth Gaussian repair contour with low roughness is obtained. Experimental results prove that the open CNC system for finding and repairing surface damage on KDP crystal meets the requirement of efficient detection and ultra-precision machining.

PC-based software computer numerical control (CNC) system is the ideal for open CNC system, but there are some problems about the current open CNC system, such as the limitation of interpolation cycle, demanding on high-speed and high precision machining and the limitation of operation system (OS). So advances a novel PC-based architecture for compiled-type software CNC system, in the architecture, the general Windows is adopted as CNC platform and adopts two huge memories acting as data buffer to solve real time problem. And then analyzes the structure and basic principle of compiling system. The hardware has been developed based on this architecture and applied in the CNC system.

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.
