【摘要】 以陶瓷复合构件(陶瓷/玻璃钢/铝合金层叠)为例,对陶瓷/FRP层叠复合构件的孔加工工艺进行深入研究。根据陶瓷复合构件组份材料的加工特性,研制了特定组份的薄壁金刚石套料钻头,胎体采用高性能的多元合金铜基结合剂,经热压烧结制成。通过加工对比试验,确定了定压进给的加工方式。分析了陶瓷复合构件的各种孔加工缺陷,提出了施加预压应力的工艺措施以提高加工质量,并通过有限元分析从理论上说明了该工艺方法的有效性;在此基础上可采用水冷却的方法。该加工工艺可推广应用于类似结构和组份材料的轻质复合构件。更多还原

【Abstract】 Drilling process of the ceramic composite component(ceramics/FRP/aluminum alloy),as an example of ceramics/FRP laminate composite component,was studied intensively.According to the diverse machining properties of the composing materials of ceramic composite component,the special thinwall diamond core bit was developed,with copper based matrix of complex alloy and hot pressing process.Through machining competitive experiments,the feeding mode with constant pressure was determined.After analyzing the diverse hole defects,the process equipment with compressive pre stress was introduced to improve hole drilling quality,with good validity proved theoretically by a finite element analysis and on this condition,water can be used as the coolant.The process technology presented in this paper can be used for hole drilling in similar composite components made of the same composing materials.更多还原
