ABSTRACT
Summary two-axis CNC Workbench is an open-loop control system for mechanical and electrical systems design, its structure is simple, easy and can guarantee a certain degree of accuracy, reduce costs, is the simplest application of microcomputer control technology. Open-loop control can make full use of computer software and hardware capabilities for control of the machine tool, machine tool machining range of expanded, further improve the accuracy and reliability of machine tools. Machinery section of this article adopts stepping motor by dragging the table in gear-driven ball screw linear rolling guide on movement, of which, step motor selection 90BYG22602 model. Table control section AT89C51 microcontroller as the core, as master; leverage 8,155H chip for connection to the keyboard/monitor; select stepping motor drive BD28Nb-drive stepper motors for operations such as addition, deceleration and emergency stop, enabling control over the table.
