Study On Open CNC System Platform Architecture And Its Application

CNC technology and CNC equipment is an important foundation of manufacturingmodernization,It directly affects a country’s economic development and comprehensivenational.Traditional CNC system is mostly a closed control structure,It is difficult to changethem or to add new function for users. The solution to this problem is to create openarchitecture CNC system.The research purpose of open CNC system is to build a modular,reconfigurable,extended control system.The purpose is to strengthen the function of anumerical control system of flexible.Quickly and economically respond to the new processingrequirements.Open CNC System which Based on the PC platform and Windows operatingsystems is Current research focus and direction of development of numerical controltechnology.In this paper,a comprehensive system of open architecture and system platform arestudied.Analysis of open CNC system in China and abroad research situation and In PCplatform to achieve open architecture development. At the same time,based on the PCplatform,design open CNC system hardware and software. On the hardware,ultimatelydetermine the NC embedded PC architecture,design and motion control card based on PCIbus;In the aspect of software design,use Windows2000/XP platform,take Visual C++as adevelopment tool,realize the software DIY And completed the task in laser welding systemand its application,it also reflects the basic idea of the open architecture.In the Open CNC platform,because the Windows operating system is generic, thesoftware and hardware is open. In order to facilitate the transplant system and configurationchanges, it largely achieved from hardware to software modular, it shows that the same typeof NC machine tool has popularization and application value.At the same time, furtherdevelopment and research on open CNC system has an important significance.
