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

In the present study, a theoretical model has been developed for the analysis of the dynamics of ultrasonic-vibration assisted oblique turning. Various parameters including inclination angle, normal rake angle, tool cutting edge angle, cutting velocity, feed rate, vibration frequency and amplitude were taken into consideration in addition to other dynamics parameters such as inertial effect. The thin shear plane theory was used for the analysis. The time dependent and average cutting forces could be estimated and compared with the cutting forces in conventional turning.

► A dynamics model was developed for the first time for oblique vibration turning.
► Parameters taken into consideration: inclination, rake and cutting tool edge angles.
► Other parameters: cutting speed, feed rate, vibration frequency and amplitude.
► Dynamics parameters such as inertial effect were also taken into consideration.
► Results will be verified by experiments in part III.
