2、各支承孔与装配基 准面之间应有一定距 离尺寸精度的要求。 铣削是采用被称为铣刀的多刃旋转刀具完成的机加工作业。在此工艺中，金属去 除是通过铣刀的旋转运动和工件的直线运动的组合实现的。 由于同一时间只有部分切削刃切削工件，因此可以在对刀具寿命没有不利影响的情 况下承担重型切削。事实上，铣削允许的切削速度和进给比车削或钻削高三到四倍。此 外，由铣削加工的表面质量通常优于车削、刨削或钻削加工的表面质量。工业上可采用 的铣刀类型众多。连同铣床是极通用机床的事实，使得铣床成为机加工车间的支柱。 关键词：关键词：箱体，箱体， 铣削铣削, , 铣刀铣刀 THE DESIGN OF REDUCTION CAS

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 cutt

6、er 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 surfaces machined by turning, shaping, or drill
