摘要/Abstract

摘要： Nomex蜂窝芯是典型的难加工材料，具有高比强度，比刚度及各向异性的特点。超声辅助切割是蜂窝芯复合材料的一种高效加工方法，可以得到比高速铣削更好的加工质量。但是在超声切割加工过程中依然会存在不同程度的纤维拔出，酚醛清漆层剥落等加工缺陷特征。为了研究其微观形貌特征，采用纵切，斜切，横切三种方式切割蜂窝芯，并对蜂窝芯的加工形貌进行观测。根据微观形貌在蜂窝芯壁上的位置，分别归纳为酚醛清漆层、热压芳纶纸层和蜂窝壁的形貌。研究超声刀具加工参数对材料破损形貌特征的影响。结果表明在10 μm到30 μm范围内提高超声刀具振幅，在500 mm/min到3 500 mm/min范围内降低进给时会降低蜂窝芯加工过程中的酚醛清漆层剥落的几率。

Abstract: Nomex honeycomb composite material is a kind of typical hardworking material, with the characteristic of anisotropy. Ultrasonic assisted cutting is a kind of high-efficient method that can get better macro processing morphology when processing honeycomb composite materials. Nomex honeycomb composite material with method of ultrasonic assisted cutting would arise varying degree of manufacturing deficiency that contains fiber pulling and the peeling off phenolic resin. In order to research the microscopic shape characteristic bringing by ultrasonic assisted cutting. Machined surfaces are observed by digital microscope, and classified by the cutting modes which contains lengthwise cutting, oblique cutting, and across cutting. Processing plane is summarized by the location of feature. Influence of feed rate and ultrasonic tool amplitude to the damage forms are researched. The result shows that the probability of phenolic resin peeling would be reduce when increasing amplitude in the range of 10μm to 30μm or decreasing feed rate of ultrasonic tool in the range of 500 mm/min to 3 500 mm/min.
