The rectangular coordinate CNC pipe profile cutting & welding integrative equipment is researched for the requirements of cutting and automatic welding of complicated butt pipes intersection lines. The mechanical structure of the equipment is that the workpiece is placed onto the supports, the chuck is carried out with limitless rotary movement. The main body for holding cutting torch and welding torch is adopted with cantilever arm traveling structure, and is controlled by six-axis digital AC servo system. The CNC system is developed based on Windows operation system, and it is a kind of pure software open architecture. RTX real-time extension technology is adopted to realize the high real-time requirement in motion control. The minimum deviation method is used to realize the interpolation algorithm of curve which describes the space track of intersection line. The equipment has realized the pipe cutting for blanking and welding for assembling at the same working position, and can meet the requirements for automatic pipe processing technology.

In this paper we propose a novel Adjustable Integrating Pointing device Driver (AIPDD) using software technology to redesign mouse driver to integrate the functions of commercial pointing devices to help them to effectively utilize commercial pointing devices to operate computers. In contrast with the latest studies, the software-based AIPDD has the following benefits. (a) It does not require additional hardware cost and circuit preservation. (b) It supports all commercial pointing devices with standard interfaces of a computer, including PS/2, USB and wireless interfaces. (c) It can integrate unlimited devices simultaneously. (d) It is adjustable in real time. In summary, the AIPDD has the benefits of flexibility, low cost, high efficiency and high device compatibility.
