钛合金椎间融合器加工关键技术研究

Study of Key Machining Technologies of Titanium Alloy Intervertebral Fusion Cage

因钛合金材料具有无毒、无磁性和良好的生物相容性,在医疗器械等行业得到广泛应用。针对钛合金材料的特点和加工特性,以椎间融合器为研究对象,制定加工方案,设计工装夹具。利用SolidWorks Simulation有限元分析软件,对采用不同走刀路径切削时零件的应力、位移和应变进行分析比较,确定合理的走刀路径,为加工满足精度要求的同类零件提供一定的借鉴作用。

Titanium alloy has been widely used in medical devices and other industries because of its non-toxic,non-magnetic and good biocompatibility.According to the characteristics and processing characteristics of titanium alloy material,the intervertebral fusion cage is taken as the research object,the processing scheme is formulated,and the fixture is designed.SolidWorks simulation finite element analysis software is used to analyze and compare the stress,displacement and strain of parts when cutting with different tool path.It determines the reasonable tool path,and provides some reference for machining similar parts to meet the accuracy requirements.
