Analytical modeling and experimental investigation of ultrasonic-vibration assisted oblique turning, part I: Kinematics analysis

The purpose of the present study is the kinematics, dynamics and experimental investigation of ultrasonic-vibration assisted oblique turning. The results are presented in three parts. In the first part, the kinematics of the relative motion between the cutting tool and the work-piece is concerned. The vibration cutting is an intermittent process and cutting in this process is physically implemented in part of the vibration cycle. The critical cutting speed and the cutting duration in vibration oblique turning are other important kinematics factors which are dealt with in this part. For this purpose, three different models have been developed and examined by different case studies.

► A kinematics model was developed for the first time for oblique vibration turning.
► Feed rate was considered, providing new insights into the kinematics of process.
► Three models were developed for critical speed and cutting duration in each cycle.
► The results were examined by different case studies.
► The results will also be verified by experiments in Part III.
