At present, from the selection of the chip to the molding of the product, the embedded CNC system will encounter various problems, such as insufficient performance of the processor, hidden dangers of the physical communication scheme between the chips, insufficient reconfigurability of the platform, and transmission rate limitation and so on. This makes the development cycle of the embedded numerical control system very long. This paper combines the rapid development and mature multi-core technology of electronic products, and develops an open multi-core embedded CNC system platform based on high-performance TMS320DM8148. The overall structure of the platform is based on a multi-core CNC system, including hardware platform construction and circuit design, dual-core and inter-core communication, and dual-core and FPGA high-speed bus communication. The reconfigurability developed by FPGA is used to develop each module in the CNC system and achieve many Axis servo driver control, and finally gives the system startup and control process, the firmware program is written to the dual-core CNC system for actual processing experiments. From the results of the performance test of the CNC system, the indicators could meet or exceed the performance requirements of the existing high-performance CNC systems, and also have open, modular and network control functions. The system platform has been successfully applied Five-axis linkage CNC machine tools, CNC milling machine, CNC engraving machine, all-electric servo CNC bending machine, spring machine and other types of CNC machine tools, reducing the design difficulty, greatly reducing the development cycle, allowing users to focus on solving specific applications Problems, and it thus quickly promote the development of the national economy and the overall level of industrial manufacturing, and has produced a very good economic and social benefits.
