缸盖组合刀具加工工艺参数的设定与研究

The Setting and Research of the Technological Parameters of Compound Cutters for Cylinder Heads

为提高加工效率或获得较高的同轴度等形位公差精度,常采用将不同加工部位的刀具组合在一起形成组合刀具,但由于各部位加工参数不同,导致组合刀具在设定加工参数时难以选择最佳参数,从而出现部分加工部位粗糙度不佳、刀片磨损加剧等现象。针对该问题,以某型缸盖所使用的组合刀具为例,开展组合刀具设计、刀片选用、工艺参数设定等方面的研究,提出了工艺参数设定的原则与试切原则,从而得到相对较佳的工艺参数。

To improve machining efficiency and obtain high machining accuracy, such as concentricity, compound cutters for varied positions are usually required. However, due to the different machining parameters, it is hard to detemfine the best technological parameters with the compound cutters, thus some parts may turn out to be rough or the cutter may wear abnormally. To deal with this problem, the compound cutters for a certain type of cylinder head was taken as an example to carry- out research on the design of com- pound cutters, cutters selection, the setting of technological parameters, etc. The principles of the parameters setting and trial cutting were put forward, and relatively better parameters were obtained.
