为了满足机床的高精度、高刚度、高速度和复杂运动的要求，用三维CAD建立整机数字模型，对在设计阶段采用虚拟现实制造技术开发五轴加工中心新产品进行了研究。在虚拟模型上进行机床运动分析和机构干涉检查，采用有限元方法做动力学仿真分析，温度变化和热变形误差分析，以及加工和装配工艺分析等。在虚拟样机上的研究结果被用来在设计过程中改进机床。%To meet the machine tool requirement of complex movement, highaccuracy, high rigidity and high speed, 3D CAD software is used to model the whole machine digit model. The research work applied virtual reality manufacturing technology to exploting 5-axis machining center in design phase is introduced . Kinematics analysis and interference check for machine tools have been done based on the virtual model. Machine tool dynamics analysis, and thermal error are analyzed by finite element method. Finally, simulation of machining process and assembling on the model is executed. All the results of the research on the virtual model are used to improve the machine in design.
