Abstract

Advanced CNC machine tool is one of the high-end equipment to promote the innovation and development of manufacturing industry, and electric spindle is the core component of CNC machine tool. Control system is the brain of CNC machine tools, responsible for receiving user instructions, sensor signals, feedback signals, after data processing and logical operation, send control instructions to the executive parts, so the design of the control system play a crucial role. This paper first constructs the hardware platform of two central control units, and designs the hardware circuit of DSP system, then constructs the three-layer software structure, and designs the flow chart of the main program, distributes the interrupt resources, and finally designs the flow chart of interrupt and fault protection subroutine. The experimental test shows that the maximum temperature rise of the enclosure of the electrical spindle prototype is 15.6 °C when the no-load 20000 rpm is stable, and the maximum radial runout is 1.5 um during the static test. The control system designed in this paper can meet the high-performance control requirements of electric spindle, and lay a good foundation for the later research of high precision control and holding technology.

高档数控机床电主轴控制系统设计

先进的数控机床是推动制造业创新发展的高端装备之一，而电主轴是数控机床的核心部件。控制系统是数控机床的大脑，负责接收用户指令、传感器信号、反馈信号，经过数据处理和逻辑运算后，向执行部件发送控制指令，因此控制系统的设计起着至关重要的作用。本文首先构建了两个中央控制单元的硬件平台，设计了DSP系统的硬件电路，然后构建了三层软件结构，设计了主程序流程图，分配了中断资源，最后设计了中断和故障保护子程序流程图。实验测试表明，在空载20000 rpm稳定运行时，电主轴样机外壳最大温升为15.6℃，静态测试时最大径向跳动为1.5 um。本文所设计的控制系统能够满足电主轴的高性能控制要求，为后期高精度控制与夹持技术的研究奠定了良好的基础。
