摘要
工业生产中,稀土金属的碳含量常用化学分析法检测,由于化学分析法检测环节多、周期长、成本高等缺陷,提出一种基于切削力模型的钻检方法,研究合金切削力与镨钕合金碳含量之间的规律。首先,阐述了镨钕合金的制备工艺及其碳含量的现有检测手段,由于化学检测法的不足,提出基于切削力的物理软测量方法;其次,根据镨钕合金钻削制孔过程中的不同阶段,通过构建局部微元力与整体切削力的转换矩阵模型,建立了制孔过程中的动态切削力模型;最后,通过搭建一套镨钕合金切削力检测设备,实验测量镨钕合金制孔切削力,验证了基于切削力模型检测稀土金属中碳含量的有效性。
During actual production,the carbon content of rare earth metals such as praseodymium and neodymium alloys is commonly detected by chemical analysis methods.Due to the defects of chemical analysis methods such as multiple detection links,long cycles and high costs,this paper proposes a drilling inspection method based on cutting force models to study the relationship between cutting force and the carbon content of Pr-Nd alloy.Firstly,the preparation process of praseodymium and neodymium metals and the existing detection methods for carbon content are described.Due to the insufficiency of chemical detection methods,a physical soft measurement method based on cutting force is proposed;Secondly,according to the drilling process of praseodymium and neodymium alloy at different stages,by constructing the conversion matrix model of the local micro-element force and the overall cutting force,the dynamic cutting force model in the hole making process was established;Finally,by building a set of praseodymium-neodymium alloy cutting force detection equipment,experimental measurement of cutting force of praseodymium-neodymium alloy was carried out.The hole cutting force verifies the effectiveness of detecting the carbon content of rare earth alloys based on the cutting force model.
