摘要: 机床加工性能和刀具切削性能的发展使得薄壁件的高效率和高精密加工成为可能,也使得薄壁件在航空航天领域得到更广泛应用。薄壁零件结构复杂、刚度低,在铣削过程中易发生变形,因此精准预测与控制薄壁件的加工变形是机加工领域亟需解决的工艺难题。通过对薄壁件分类以及加工工艺分析,归纳总结引起薄壁件加工变形的因素,对加工变形影响最为关键的铣削力计算模型进行简述;结合国内外薄壁件变形预测与控制方法的研究,以弹塑性和数值模拟方法对薄壁件加工变形进行预测,通过加工工艺优化、辅助支撑技术、高速切削技术和数控补偿技术等方法对薄壁件加工过程的变形量进行控制;基于数据驱动数字孪生体的更新迭代,实现薄壁件实际加工过程的孪生及薄壁件变形预测与控制,构建了以数字孪生为平台的薄壁件加工变形预测与控制理论框架;最后对数字孪生在薄壁件加工变形预测及控制的发展与应用提出展望。

Abstract: With the development of machine tool machining performance and tool cutting performance, thin-walled parts can be machined with high efficiency and precision, leading to their wide use in the aerospace field. The complex structure and low rigidity of thin-walled parts make them easy to deform in the milling process. Therefore, accurate prediction and control of thin-walled parts deformation is an urgent technical problem to be solved in the field of machining. Through classification of thin-walled parts and analysis of the processing technologies, the factors causing the deformation of thin-walled parts are summarized, and the most basic calculation model of milling force is briefly introduced. Research on deformation prediction and control methods of thin-walled parts at home and abroad is reviewed. It is found that deformation of thin-walled parts is predicted by using the elastic-plastic theory and the numerical simulation method, and deformation of thin-walled parts is controlled by process optimization, auxiliary support technology, high-speed cutting technology and numerical control compensation technology. Based on update and iteration of data-driven digital twins, deformation prediction and control of the actual processing of thin-walled parts are realized. The theoretical framework of deformation prediction and control of thin-walled parts processing is built based on digital twins. Development and application prospects of digital twinning deformation prediction and control in thin-walled parts processing are also discussed.
