工程陶瓷脆性域旋转超声磨削加工切削力研究
Investigation of the cutting force of rotary ultrasonic grinding machining in the brittle regime for engineering ceramics
摘要
Abstract
The theoretical investigation of the cutting force of rotary ultrasonic grinding machining ( RUGM) for en-gineering ceramics in a brittle regime was conducted for the purpose of solving the limitations of the experimental re-sults due to the limited range of process parameters and the number of experiments. Based on the mechanism of RUGM, the formula of the cutting force caused by the bottom and side machining of a single diamond in the brittle regime was deduced by the theorem of linear momentum and kinetic energy, and was combined with the indentation fracture mechanics and elastic-plastic mechanics. Meanwhile, the mathematical model of the cutting force for RUGM in the brittle regime was established. Finally, the model was verified by the experiments. The results show that the error rate of the cutting force model between the calculation value and the experimental value is less than 8%. As a result, it can meet the demands of engineering applications. So it provides the foundation for process pa-rameters optimization.关键词
