To meet the need of numeric-control machine tools’ development, five-axis head have become an important development trend now. The main task of the design is the design of 5-axis head.5-axis head is a kind of equipment in 5-axis With strong numerical function, the machine tool is the key equipment in the efficient and high-accurate machining of curly-faced . work-piece, namely. Variation molds, vane of water turbine and steam turbine, ship-used propeller, promoter and gears. It can clip a work-piece going through milling, boring and drilling, it can also process. A variety of work-pieces with complex outlook and cavities. It is capable of drilling and milling. It can be applied to all kinds of mechanic manufactures; especially molds manufacture. It can control five axis, simultaneous operate five axis. At a high speed the spindle electrical machinery uses A.C driving system, which enables the spindle to vary speeds infinitely. With a command of the baric functions of the Pro/E software, different parts of the machine tool are designed, assembled ， thus achieving the desired requirement. Keywords control five axis simultaneous operate five axis virtual－made virtual－assembly 目 录 第一章 概述----------------------------------------6 1.1 国内外相关技术现状-------------------------6 1.2 课题研究涉及内容----------------
