轮廓插补实验装置设计 摘 要 本课题针对数控技术、通用数字量I/O接口卡和轮廓插补技术的现有技术以及其发展趋势，设计一种以轮廓插补实现2坐标联动控制的数控实验装置，用于课程的实际教学。着重研究了PCI-1751卡的功能，控制系统的硬件和控制系统软件的设计。 通过对插补模块的设计，使设计的软件具有插补功能，把Visual C++ 6.0作为开发工具，使用MFC类库实现了插补过程的动态仿真功能。该控制系统能够很好地满足系统实时性和可靠性的要求。 实现了人机交互界面、直线插补、圆弧插补控制、步进电机控制的和驱动及参数设置等功能模块。深入研究了数控代码的译码，实现了数控程序打开、存储等程序管理功能。探讨了系统软件的质量保障，基于对控制系统的中断响应和实时性问题的研究，开发实现了坐标显示，运动控制和状态显示，提高了软件系统的稳定性。 关键词：数控系统，系统人机界面设计，插补和步进电机控制模块,步进电机控制和驱动，接口线路设计，运动控制，实时性 Contour Interpolation Experimental Device Design ABSTRACT The topic for the CNC technology, general digital I / O interface card and the contour interpolation technology and its development trend of current technology to design a contour interpolation to achieve two axis CNC control experimental device used for the actual course teaching. Focus of the PCI-1751 card function, the control system hardware and control system software design. By interpolation module design, the software have interpolation function, the Visual C + + 6.0 as a development tool, the interpolation process has achieved the dynamic simulation by the MFC, The control system can satisfy real time and reliability requirements. Realize human-machine interface, linear interpolation, circular interpolation control, stepper motor control and drive modules and parameter settings. In-depth study of the NC code decoder, to achieve the NC program to open, storage management functions such procedures. Of the system software quality assurance, control systems based on real-time interrupt response and issues research and development to achieve a coordinate display, movement control and status display, software to improve the stability of the system. Keywords: CNC system, the system man-machine interface design, interpolation, and stepper motor control module, stepper motor control and drive, interface circuit design, motion control, real-time 目 录 摘要 Ⅰ ABSTRACT Ⅱ 1 绪论 1 1.1 数控技术发展过程 1 1.2 数控教学实验系统发展 2 1.3 数控未来发展的趋势 3 1.4 本课题的研究目的及意义 3 2 系统总体方案设计 5 2.1 方案选择 5 2.2 系统组成 5 2.2.1
