基于S3C44BOX的嵌入式磨削数控系统

Abstract： This paper presents an embedded numerical control system of grinder，including its design of hardware and software. The controller is S3C44BOX, the operating system is ｕC/OS-II, the machining-information is transferred by USB flash disk, the motor is controlled by PWM mode, the system information is displayed by LCD displayer in the proposed system. It has many advantages such as higher control accuracy, lower cost, smaller volume etc., and meanwhile it is extended and upgraded easily . It befits the reconstruction for traditional machine tool, and also befits the development for economical numerical control system.
