摘要
C/SiC复合材料是一种高强度,高韧性,轻质,良好的抗疲劳性和减震性,设计性强的先进材料。目前被广泛应用于航空,航天,和其他军事领域,并具有广泛的应用前景。由于C/SiC复合材料加工过程中加工缺陷多、刀具磨损严重、加工效率低且加工成本高等问题,本文通过锥形工具磨削加工C/SiC实验来研究不同加工参数对磨削力的影响。实验结果通过方差分析,信噪比和主效应图来评价;基于望小模型获得了本次实验参数范围内的最佳加工参数:主轴转速为4500r/min,进给速度为100mm/min,磨削深度为0.2mm。
C/SiC composite material is an advanced material with high strength,high toughness,light weight,good fatigue resistance and shock absorption,and strong design.At present,it is widely used in aviation,aerospace,and other military fields,and has a wide range of application prospects.Since the processing of C/SiC composites is often accompanied by fiber break-out,chipping,burrs,tearing and delamination and other defects,as well as serious tool wear,low processing efficiency and high processing costs,this paper uses tapered tool grinding Cutting C/SiC experiment to study the influence of different processing parameters on grinding force.The experimental results are evaluated through analysis of variance,signal-to-noise ratio and main effect diagram;based on the characteristics of the small model,the best processing parameters within the parameters of this experiment are obtained:spindle speed is 4500r/min,feed speed is 100mm/min,the grinding depth is 0.2mm.
