NC-based single-chip two-dimensional test-bed design and implementation
Abstract
The combination of mechanical and electrical design aspects of the integration of teaching needs, the design of control systems with single-chip microcomputer as the XY table. XY table through on the design of mechanical structure and control interface circuit design, mechanical-electrical integration on the design of the common and key technologies.
Two-dimensional numerical control system based on single-chip based on single-chip microcomputer as the main body, the experimental two-dimensional numerical control system as the core platform. The main application of single-chip microcomputer as control core, LED dot matrix display system chips with a combination of CNC system. Give full play to the single-chip performance. Advantage of simple hardware circuit, software functions, the control system reliable and cost-effective features such as high, with a certain degree of use and reference value.
The system design is an open-loop control system, its simple structure, convenient and can realize. Sure. Reduce cost, is the most simple control technology application. It fully utilize the MCU software and hardware function to realize the control of machine tools, Machine processing expanded, accuracy and reliability is further improved.
System design is to use 27128,6264，AT89S51 and memory and 8155 chips, hardware composition in the control system of the hardware written procedures to achieve certain processing function. The basic idea is: through the single-chip microcomputer control make motor sports so as to realize the worktable moving.
Key words: X-Y table; singlechip; mechatronics design
课题研究主要内容
二维数控实验平台系统设计是利用AT89S51单片机,及27128,6264存储器及8155芯片等硬件组成,在控制系统的硬件上编写一定的程序以实现一定的加工功能.其基本思想是:通过单片机控制使电机运动从而实现工作台的移动。
经济型数控机床驱动电机采用步进电机，多数采用开环控制，需要选择和计算主要机械传动部件，如滚珠丝杠，螺母副和步进电机等，绘制机床进给传动机构装配图，绘制单片机控制系统的硬件线路图。
