| CNC technology is the important basis of intelligent manufacturing and information technology. In the new era, it’s a major task to develop CNC technology, breakup the monopoly of foreign CNC industry and realize the domestic production of high-performance CNC system. In recent years, as the microprocessor industry develops rapidly, high-performance and high-integration microprocessors spring up. Embedded CNC system which combine the embedded system and CNC technology come into being and has become the hotspot in the field of CNC technology. Therefore, it is of great significance to develop the embedded CNC system and realize the independent production of high performance embedded CNC system.The embedded Linux system is built on the hardware platform, it contains OMAP3530 and FPGA. The most basic task is to build Linux system on the hardware platform. The first step is to transplant and configure the bootloader and the standard Linux kernel, then design and make the file system of Linux system and device driver programs, the second step is to complete the development of CNC software on Linux system. For the real-time performance of embedded CNC system, the real-time problem is solved through transplanting Xenomai kenel and developing dual-core communication based on DSPLINK. The real-time performance of embedded CNC system will be futher improved through the distribution of the CNC tasks. After that, a look-ahead algorithm based on the cubic polynomial acceleration and deceleration control model is established and studied. |
