模块化设计方案数控机床结构运动仿真系统的建模.docVIP

【摘要】数控车床在工业自动化控制中有着广泛的应用．数控车床的控制系统也随着计算机的不断推广而得到进一步优化．本文就是一篇关于数控车床控制系统的设计论文．它首先概述了数控车床在当今信息工业社会中所扮演的重要角色．以及它的发展概况．然后通过对数控车床工作原理的阐述引出了几种数控车床控制系统的方案论证．其中包括了过去长用的数控车床系统，及现代常用的微计算机控制系统．通过这几种方案的比较，确定了由单片机控制步进电机转速的系统设计方案．并逐一介绍了系统的硬件电路及软件程序设计．其中在硬件电路中对8031及其外部扩展电路，光电耦合器电路，功率放大电路等几部分的功能及特性进行了详细的描述及参数分析．而软件部分则进行程序设计．且每个汇编程序都附有程序流程图，内容详尽．本文还涉及到51系列单片机应用设计，计算机接口技术，模拟电路等几门课程的基础理论．最后通过实验来验证该系统的正确性与可操作性． 技术要求：主控采用单片机控制，刀台用两台步进电机实现X——Y平面的自动加工， 加工精度：误差≤0.01mm完成方案的设计、论证、包括：硬件设计、软件设计关键字：数控车床 单片机 控制linear cutting线切割 electrical sparkle电火花CNC lathe electrical designAbstractThe CNC lathe have got the extensive application in industry automate control. A control system for CNC lathe also expands continuously along with the computer but get further excellent turn. This text is a design for concerning CNC lathe controling system thesis. It said an important role for CNC lathe in now information industry society playing at first. And it of development general situation. Then pass to a project for CNC lathe working principle expatiating derivation a few controling system argument. Among them included to pass by system of progressive concle, and modern in common use microcomputer control system. Comparison them and then make sure the plan that use microcomputer to control it. And combined to introduce hardware circuit and software designs of the system one by one. In hardware circuit, to the 8031 and its peripheral expands circuit, the photo coupler circuit and power amplifier circuit etc. Several part of functionses and characteristics proceeded to describe detailedly and parameter analysis. But the software part example proceed the procedure design. And each one assembler collected flow chart, the contents is detailed. This text still involves the foundation of some subject which are 51 microcomputer application design in serieses, the computer interfacing and analogous circuit in etc..Pass the experiment finally to the accuracy that verify that system and maneuverability.
