摘　　要：针对桌面数控车床对成本和体积提出的新要求,研究设计出基于双STM32和FPGA的嵌入式数控系统。将数控系统加工模式重新划分,并按客户机-服务器设计模式将数控系统任务划分为两部分。针对两部分的任务需求设计对应的硬件系统,在相应的硬件平台研究实现具体软件功能。最终在两台不同桌面车床进行车削实验,验证修改数控系统在功能、精度和稳定性等方面的不足,实验证明嵌入式数控系统能满足一般数控加工需求。For lowering the cost and volume of desktop CNC lathes,an embedded CNC based on STM32 and FPGA is researched and designed.The CNC operating modes are redivided,and the whole CNC tasks are divided into client and server according to the client-server structure.According to the task requirements of the two parts,the corresponding hardware is designed,the specific software functions are studied and implemented.Finally,experiments were performed on two different desktop lathes to verify then modify the deficiencies of the CNC in terms of function,accuracy and stability.The experiment proved that the embedded CNC could meet the general CNC machining needs.
