Designs In Distribute-and-parallel Five-coordinate CNC Structural System Based On IPC

This thesis introduces designs in distribute-and-parallel five-coordinate computer numerial control structural system based on [PC. include it's system constructural and designs in control system software. This system adopts modularized structure and openrized system,with the advantage of high precision,high-speed response,high efticiency,good stability,besides adopts exterior interrupt to realize dynamic detection and close loop control.It can be used for other related CNC field. The control system adopts a new special software structrual which separates part of interpolate calculate out of the real-time manufacturing process,and put it into no real-time pretreatment phase,bring about two relatively independent mould.The no real-time interpolate calculate separate CNC souce code into command information and data information,then invert it into assigned style and put them into computer抯 memory and data group separately.ln real-time rnanufacturing,the program read command information from memory and get data information from data group by turn then give it to the intellective motion control card(IMCC) to invert it to homologous control signal to control process trail. The system combines software and hardware, lop software only complete manufacturing trail's stylize section and data classified. The control chip of IMCC has some correlate function lib,it realize bottom real-time interpolate.This kind of method not only raise the system real-time capability but also control speed facilitately.The mouldlarize design method also predigests the software structure,reduces the time spend on the development of software and makes the system more general and economical.
