数控旋转超声波铣削加工材料去除量的数学模型及实验

摘要

The ultrasonic machining is suitable for machining of hard brittle materials .This article is combining rotary ultrasonic machining and CNC technology ,i .e .,the ultrasonic oscillation ,tool rotation and machine tool feed under three kinds of movement combination ,based on the theory of hard brittle materials indentation fracture ,analysis of material removal mechanism , to establish the mathematical model of material removal amounts ,and the material removal amounts have been determined and the relationship between the various process parameters is obtained .%超声波加工适合于加工硬脆材料。该文将旋转超声加工与数控技术相结合，在超声振荡、工具旋转以及机床进给3种运动综合作用下，以硬脆材料压痕断裂理论为基础，分析材料的去除机理，建立材料去除量的数学模型，并通过实验得出材料去除量与各工艺参数之间的关系。
