摘要
具有微小孔特征的零件在许多关键机械装置或产品中发挥着重要作用,微小孔的表面糙度和毛刺会大大增加微小孔的流动阻力,降低流量系数值。微小孔去除毛刺后可有效提高流量系数值,微小内孔去毛刺技术一直是业界难题。介绍了一种微小孔挤压研磨技术,采用正交实验法探索了工艺参数与加工质量的逻辑关系。通过对不同加工参数集的评价指标进行计算分析,给出了各参数重要性次序,推荐了较优的加工参数集,通过实验对优选参数的有效性进行说明。
Workpieces with micro-orifices play great roles in many key mechanical devices and products. But the resistance from burrof orifices will reduce the flux. The flow coefficient can be improved effectively after deburring is removed. But acturally microorfices’deburring is always a hard problem. A grinding method was introduced to deburr and orthogonal experiments which are used tostudy the relation between result after processing and the grinding parameters. After analysis of the evaluation of diffferent processingparameters, the importance of parameters were concluded to each evaluation target and selects the parameter set. At last, experimentsunder the parameter set show that the grinding parameter set is useful for quality of micro-orifices.
