Abstract: Aiming at the poor machining quality of workpiece caused by lack of systematic theory and blind selection of processing parameters of ultrasonic cutting honeycomb composites, study on ultrasonic cutting force and selection of processing parameters of ultrasonic cutting honeycomb composites on straight blade cutter were carried out. The theory model between ultrasonic cutting force and process parameters was established base on analysis of tool′s kinematics characteristic. Based on model, the change of cutting force caused by ultrasonic vibration energy was investigated. The influence rules of processing parameters on ultrasonic cutting force were investigated through simulation analysis on the Matlab software. The results indicate that ultrasonic cutting can effectively reduce cutting force compared with traditional machining, nose angle and blade surface angle has the most significant influence on cutting force, the next is top angle, however swinging angle has minimal influence on cutting force, and lays the good theory foundation for reasonable selection and further optimization of processing parameters.
