Abstract: A simulation system of numerical control was introduced. The numerical controlling program is converted into the codes which have been widely used in serial communications.The host computer makes use of  the  MSComm control of Microsoft while the slave computer uses the common MCS51 MCU in order to realize the serial communications. In the mainframe controlled, the system can complete line and circular interpolation and control two stepper motor concerted campaigns. The electrical controls and motors driving circuit, serial port procedures which at the same time to establish a good relationship interface were described. The results of the research show that the system can be widely used in teaching demonstration, arithmetic checks as well as scientific research.
