【摘要】 随着时代的发展,数控技术获得了广泛的应用,国内许多高校都在开展或计划开展数控技术教学。鉴于此,本文结合数控技术实际教学实验的需要,根据数控系统的工作原理,研究开发了一套实验教学型数控系统。文中首先总结了国内外数控技术的发展现状和趋势,确定HFUT-1实验教学型数控系统的研制方案。讨论了经济型数控系统工作原理和功能,在此基础上,系统地分析了所研制数控系统的硬件设计和软件功能设计。系统硬件设计时,选用AT89S52芯片作为控制核心。系统的软件功能设计主要包括编辑、自动加工、模拟和参数设定等功能设计。另外,本文就研制数控系统过程中的几个关键问题展开了深入的研究,即:插补原理与方法、液晶显示的实现、刀补原理与实现方法和半闭环控制研究。最后,文章展望了实验教学型数控系统发展趋势。更多还原

【Abstract】 With development of technologies, NC technology has been used widely, the teaching of NC technology is planed or processed in many universities at present. In view of this, this paper proposed developing a set of teaching experimental numerical control system for sake of the requirements of NC Teaching & Experimenting on the basis of NC theoryAt first, this paper summarized the current status and development tendency of the domestic and foreign NC technology, drawn up Design proposal of HFUT-1 teaching experimental NC system. Discussed the work and function of the economical NC system principle, in the foundation, systematically analyzed the hardware and software functional design of the numerical control system is developed. When the system hardware is designed, chose the AT89S52 chip as the control core. The system software functional design mainly includes edition, automatic processing, simulation and parameter hypothesis.Moreover, this paper discussed the solution of the four key problems in detail. Namely: the principle and method of interpolation, the realization of liquid crystal display, tool compensation and its realization method, semi-closed control research. Finally, the paper has forecast the tendency of teaching experimental NC.更多还原
