Design of servo system for 3-axis CNC drilling machine based on XPC target

As special equipments, the CNC drilling machines require servo systems specially designed. 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-axis CNC drilling machine based on xPC Target is presented in this paper. Taking a CNC drilling machine model as the experiment platform, the block diagram of the servo system was designed using SIMULNK tools, and compiled into a real time system by VC complier, which could run on X86 computer. Rapid developing of a servo system for 3-axis CNC 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.
