摘要

数控机床即数字程序控制机床，是一种自动化机床，数控技术是数控机床研究的核心，是制造业实现自动化、网络化、柔性化、集成化的基础。随着制造技术的发展，现代数控机床借助现代设计技术、工序集约化和新的功能部件使机床的加工范围、动态性能、加工精度和可靠性有了极大的提高。

本文主要对XK5040数控立式铣床及控制系统进行设计，首先分析立式铣床的加工特点和加工要求确定其主参数，包括运动和动力参数；根据主参数和设计要求进行主运动系统、进给系统和控制系统硬件电路设计。主要进行主运动系统和进给系统的机械结构设计及滚珠丝杠和步进电机的选型和校核；对于控制系统由于这里主要针对经济型数控铣床的设计，这里采用步进电机开环控制，计算机系统采用高性能价格比的MCS-51系列单片扩展系统，主要进行中央处理单元的选择、存储器扩展和接口电路设计。

由于本文采用8031单片机控制系统，因此，设计出的立式铣床性能价格比高，满足经济性要求。可实用于加工精度较高的场合。

ABSTRACT

The numerical control engine bed is the digital process control engine bed, is one kind of automated engine bed, the numerical control technology is the core which the numerical control engine bed studies, is the manufacturing industry realization automation, the network, the flexibility, the integrated foundation. Along with the manufacture technology development, the modern numerical control engine bed with the aid of the modern design technology, the working procedure intensification and the new function part caused the engine bed the processing scope, the dynamic performance, the processing precision and the reliability had the enormous enhancement .

This article mainly carries on the design to the XK5040 numerical control vertical milling machine and the control system, first analyzes the vertical milling machine the processing characteristic and the processing request determines its host parameter, including movement and dynamic parameter; Carry on the host kinematic scheme according to the host parameter and the design request, enters for the system and the control system hardware circuit design. Mainly carries on the host kinematic scheme and enters for the system mechanism design and the ball bearing guide screw and electric stepping motor shaping and the examination; Regarding control system because here mainly aims at the economy numerical control milling machine the design, here uses electric stepping motor open-loop control, the computer system uses the high performance price compared to the MCS-51 series monolithic expansion system, mainly carries on the central processing element the choice, the memory expansion and the connection circuit design .

Because this article uses 8,031 monolithic integrated circuits control system, therefore, designs the vertical milling machine performance price is higher than, satisfies the efficient request. But practical to processing precision higher situation .

Key words：Numerical control technology， Vertical milling machine，Design
