300×400数控激光切割机XY工作台部件及单片机控制设计毕业论文

300×400 数控激光切割机 XY 工作台部件及单片机控制设计摘要：激光切割的适用对象主要是难切割材料，如高强度、高韧性材料以及精密细小和形状复杂的零件，因而数控激光切割在我国制造业中正发挥出巨大的优越性。本文设计了一台单片机控制的数控激光切割机床，主要完成了：机床整体结构设计，Z轴、XY 轴的结构设计计算、滚珠丝杠、直线滚动导轨的选择及其强度分析；以步进电机为进给驱动的驱动系统及其传动机构的分析设计计算；以 89C51 为主控芯片的数控系统硬件电路设计、系统初始化设计及系统软件方案设计和步进电机的控制程序设计。关键词 CNC，激光切割机床，XY 工作台，单片机300 × 400 CNC laser cutting machine XYtable parts and SCM control design ABSTRACT：Laser cutting machine tool was usually used for the hard-cutting material, such as high-strength material, high precision ductile materials, and smart and complicated components. So, CNC laser cutting has been playing an important role in China's manufacturing industry.This paper describes the design of a SCM-controlled CNC laser cutting machine tools. More attention was paid on the overall machine design, Z axis, XY axis in the design, ball-screw and the choice of linear motion guide and intensity analysis; the drive system into which stepper motor was put and the analysis of the drive system design; 89C51 chip was mainly used for the design of hardware circuit, the design of system initialization and the design of stepper motor’s controlling program.Key words CNC, laser cutting machine tools, XY table ,Single chip microcomputer 目 录第一章 绪论…………………………………………………………………… 11.1 激光技术概述………………………………………………………………… 11.2 激光切割机的应用…………………………………………………………… 11.3 设计任务……………………………………………………………………… 11.4 总体设计方案分析…………………………………………………………… 2第二章 机械部分 XY 工作...
