CPU can according to read the instruction information (G code and the X and Y coordinates), respectively, to X axis and Y axis stepper motor output control signal, necessary for the execution of instructions to complete the specified process. This design mainly adopts the design computer aided design is complete，Proteus simulation development platform by single chip microcomputer hardware system design, including schematic design and PCB board design, programming and debugging, using Keil C platform system alignment on the Proteus platform.，This design program can control system in the Proteus simulation circuit diagram of the simulation, the simulation, only need to input from the keyboard G code, step motor can be through the linear interpolation and circular interpolation, complete plane contour machining. Key words: Cross sliding table；Linear interpolation；The circular arc interpolation；Stepper motor；CNC programming 目录 摘 要 I ABSTRACT II 前言 1 1 双坐标十字滑台数控编程插补控制的实现设计简介 2 1.1 双坐标十字滑台总体方案分析 2 1.2 仿真开发环境Proteus简介 2 1.3 程序开发环境Keil C简介 2 1.4设计内容要求 2 双坐标十字滑台机械部件4 2.1双坐标十字滑台性能与技术要求 2.2机械部件选取 2.2.1滚珠丝杆螺母副的选型与计算 2.2.2 导轨副的选型与计算 2.2.3 步进电动机的选型与计算 4 步进电动机的工作原理及工作方式 3 数控部分 6 3.1 控制系统微控制器AT89C52 6 3.1.1 AT89C52单片机的主要工作特性 6 3.1.2 AT89C52单片机的内部结构 6 3.1.3 AT89C52单片机的各引脚功能 15 3.2 可编程并行接口芯片8
