通常加工鼓形体主要有车削和铣削两种方法。本文主要介绍用铣削加工r>R的鼓形体,和车削相比的优点是:效率高、表面光洁度好且可节省靠模板。铣削是在立铣床和龙门铣上配合分发头来加工的。工件借助于定心轴或工艺夹头装卡在分度头上,铣削时刀具按一定的偏心量和回转半径回转,分度头带动工件进行分度。这两个运动的合成就可铣出鼓形体。图1所示,1为铣刀盘、2为工件、0—0为工件回转轴心,0′—0′为刀具回转轴心,0a为鼓形体半径
Drum processing is usually the main turning and milling two methods. This article focuses on the use of milling r> R drum, compared with the advantages of turning: high efficiency, good surface finish and can save on the template. Milling is in the milling machine and gantry milling head with the distribution of processing. The workpiece is fixed on the indexing head by means of a centering shaft or a process chuck. When the tool is milled, the tool rotates according to a certain eccentricity and the radius of gyration, and the indexing head drives the workpiece to perform indexing. The combination of these two movements can mill the drum. Figure 1 shows a milling cutter disc, 2 for the workpiece, 0-0 for the workpiece rotary axis, 0’-0 ’for the rotary axis of the tool, 0a for the drum radius
