文档介绍：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。

ABSTRACT:Laser cutting machine tool was usually used for the hard-cutting material, such as high-strength material, high precision ductile materials, and smart ponents. So, CNC laser cutting has been playing an important role in China's manufacturing industry.
This paper describes the design of a SCM-C 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.
