In generating methods, hobbing is about working gears in specialized machine tools named gear hobbing machine. As for forming methods, gear milling is always handled in milling machines. By now, there has not been a case in which the two different methods are combined in the same machine tools in domestic. While at abroad ,the compound working methods are exerted on the Multi-axis linkage machine tools instead of the specialized machine tools for the working of gears. What’s worse, the multi-axis linkage machine tools are expensive in costs, complex in programming, and low in efficiency. To solve the problem, this compound machine tool could act as an specialized gear-working machine tool, and we could renovate it along the direction of compound function, motion modularization and intelligence controls. In a word ,it has the advantage of low costs and high efficiency . This paper firstly introduces one type of compound machine tools for gear-hobbing and gear-milling and analyses some core elements and mechanism of it. And then ,this paper introduces the machining of gear-milling and gear-hobbing. Besides, this paper proposes a series of renovations for this compound machine tool. At the end of this paper, an operation manu
