【Abstract】 Complex machining technology of helical milling and ultrasonic vibration is applied to the drilling of carbon fiber composite. The machining principle of ultrasonic assisted helical milling is studied. Based on the same machining efficiency, drilling experiment is carried out. Cutting force and machining quality are detected and analyzed. The impact of machining parameters on cutting force, swarf and machining quality is discussed. The results show that the complex machining method of ultrasonic assisted helical milling can be used to drilling carbon fiber composite; Machining defects, such as glitches and tearing at exit, can be effectively avoided by increasing ultrasonic amplitude or reducing per tooth removing material.更多还原
