Assembling base level and the base level fixing position in processing of the box body should have the certain flat surface degree and surface harshness request; Every holds a hole and assembles the request should have certain distance dimension accuracy between base level. Milling is a machining process that is carried out by means of a multi-edge rotating tool known as a milling cutter. In this process, metal removal is achieved through combining the rotary motion of the milling cutter and linear motions of the workpiece simultaneously. Since only a few of the cutting edges are engaged with the workpiece at a time, heavy cuts can be taken without adversely affecting the tool life. In fact, the permissible cutting speeds and feeds for milling are three to four times higher than those for turning or drilling. Moreover, the quality of the surfaces machined by milling is generally superior to the quality of su
