Summary: | The invention discloses a complete geometric chip breaking method based on longitudinal-torsional composite ultrasonic vibration drilling. The method specifically comprises the following steps: step 1, constructing a longitudinal-torsional composite ultrasonic vibration drilling kinematics model; 2, a motion trail equation of two adjacent cutting edges on the cutter in the machining process is constructed; thirdly, a dynamic cutting thickness mathematical model in the longitudinal-torsional composite ultrasonic vibration drilling process is constructed; step 4, constructing a minimum cutting thickness expression; 5, theoretical conditions for achieving complete geometric chip breaking are obtained; 6, a longitudinal-torsional composite ultrasonic vibration drilling experiment is carried out, cuttings under different machining parameter conditions are collected, and the form of the cuttings is observed; and step 7, sorting experimental results to obtain a process parameter matching criterion for realizing comp |
