This paper is major to have studied control method as well as the design of the edge mill machine of lathe tool. Have discussed mainly the mathematics between the geometry parameter and edge mill parameter of lathe tool that concerns and begs to untie method and establishes and describes the pose adjustment of lathe tool model. The paper mathematics that has discussed the edge mill of lathe tool model, according to model, beg to have untied the relation between edge mill parameter and the geometry parameter of lathe tool. Because of the edge mill parameter of lathe tool when deciding edge mill, the angle between lathe tool and emery wheel is adjusted. To determine the edge mill parameter of lathe tool of machine tool, first according to the edge mill of cutting tool the analysis of campaign space, have designed realization scheme, select to control construction of system , adopt only flat machine eventually according to edge mill sport equation control angle as 3 walks into generator control, so control machine tool to produce corresponding sport, realize every surface of lathe tool edge mill. adopt only flat machine eventually according to edge mill sport equation control angle as 3 walks into generator control, so control machine tool to produce corresponding sport, realize every surface of lathe tool edge mill.
