INTRODUCTION The CNC drilling machine is mainly for drilling holes with numerical control. The most products are special equipments, which are widely used in hole processing technology for the PCB and large porous tube sheet parts.[1] And, these products most are special equipments, can be classified as CNC vertical drill, drilling center, CNC PCB drill, CNC deephole drill and other large CNC drilling machine.[2] It is applicable to machining the parts with lots of precise holes in procedures of drilling, spreading, weaning and threading. Especially, it?s important to improve the machining accuracy and efficiency that choose a special CNC drilling machine to work the PCB and large porous tube sheet. While, the design of servo system is the most plex in the process of designing a special CNC drilling, and require plenty of time to program and debug. So, it not only consumes the valuable intellectual resources, but constrains to market the product timely. XPC Target is a tool set based on Matlab/SIMULINK that is provided by MathsWorks. It has a wealth of I/O device modules which support the majority of integrated circuit boards.[3] And, xPC Target introduced a hosttarget technical means, one PC as host puter, and another industrial puter as target puter, two puters connected with work cards and municate through TCP/IP protocol. The systems by xPC Target can run onX86 puter realtime. It achieves simulation on board and rapid prototyping of control systems. The CNC technology lab for scientific research in Guangdong province developed a 3axis CNC drilling machine model which is based on the product manufactured by Shenzhen Open Technology Corporation. Using the drilling machine model as test platform, designed the special servo system based on XPC Target . II. SERVO CONTROL SYSTEM STRUCTURE OF THE 3AXIS CNC DRILLING MACHINE The control system of the 3axis CNC drilling machineis a twolevel puter control structure: the host puteris a personal puter, and carries out 共 5 頁 第 2 頁 drawings,mands, munications etc. the lower puter is anembedded puter of PC/104, as the core unit of servocontrol system in the drilling host puter municates the data of mands and motion states with the embedded puter of PC/104 by RS232, As shown in . And, apply the Modbus munication protocol to keep the data mutually transmitted exactly. In this system, ADT652 expansion card according with PC/104 bus is used as the I/O interface of the system. Using the software of SIMULINK, designed servo control system of 3axis CNC drilling machine based on XPC Target. And, the software of the system was downloaded to the PC/104 and realtime operated aspiled and debugged successfully. After plicated puting, the PC/104 modulates the results into a corresponding PWM signal that is exported to the motor drive circuit through ADT652 board. Then, the motor driving the corresponding axis rotates at a definite speed under control. At the other side, a incremental rotational photoelectric encoder was fixed on the servo motor of the relevant feeding mechanism to obtain its position， which is fed back to the PC/104 by the I/O port of ADT652. While, the motional speed of the spindle servo motor is obtained by speed senor, and is fed back to the PC/104 by the ADC channel of ADT652. III. ESTABLISH THE SERVO CONTROL SYSTEM In general, the servo control of CNC drilling machine?s feeding mechanism is pointtopoint control. And, the feeding rate of X, Yaxis could obviously affects promotin
