Abstract: Numerical control machine tool as the exactitude, highly effective machining instrument is using more and more frequently in the machinery manufacture and processing industry, especially the single-chip numerical control system instrument machine, because of its economic and easy accessibly, it has enormous development potential and market.
This design uses MCS-51 single-chip to do the design as the numerical machine control instrument. In the system, we choose 8031 single-chip as the core control chip as the numerical system control instrument, and give it the outside expansion, input and output interface chip mainly adapt the programming I/O interface chip 8255 to achieve the related manual operation, switch command, status detection, etc. As to the display aspect, we mainly use the modular design, and utilize the MCS-51 assembly language programming to realize numerical design of every modular.
This design based on MCS-51 single chip to devise the numerical system control instrument, the automation degree is comparably high, and has good economic performance.
