So there is a substantial waste of time and energy. In order to solve this problem, a design proposal for the servo system of 3-C drilling machine based on xPC Target is presented in this paper. Taking C drilling machine model as the experiment platform, the block diagram of the servo system was designed using SIMULNK tools, piled into a real time system by plier, which could run on puter. Rapid developing of a servo system for 3-C drilling machine is easily implemented by this proposal. The experimental results demonstrate that the feed system of the drilling machine model could carry out a quick precision positioning. Key words-servo systems; drilling machines; xPC Target; I. INTRODUCTION C drilling machine is mainly for drilling holes with numerical control. The most products are special Figure 1. The control system structure of 3-C drilling machine 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 C vertical drill, drilling center, CNC PCB drill, CNC deep-hole drill and other C 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 C drilling machine to work the PCB and large porous tube sheet. While, the design of servo system is the plex in the process of d
