The Simulating Experiment System for Numerical Control of Milling Machine’s Worktable Exploitation
ABSTRACT
In this article, a set of numerical control of milling machine worktable experiment system for teaching based on single chip microprocessor for MCS—51 is designed. First, the CNC system model and characteristics based on microcomputer and status of CNC in China are presented. The development trends about open architecture, intelligence, suppression, high speed and network of CNC are analyzed and explain the function of single chip microprocessor and their calling into play in the CNC, and controlling principle of single chip microprocessor for MCS—51. This article introduces the methods and steps of the digital control system design. Emphasis is given to I/O circuit, stepping motor drive and authorized assembler and carry out the system designing request. The system offer a set of equipment for teaching, and is designed for teaching as a set of experiment or has a great affect to the digital control reform of the machine tool.
KEY WORDS: Single Chip Microprocessor; Worktable of Milling Machine; Stepping Motor, Interface Circuit, Assembler
