Generalized Chip Formation and Thermal Dynamics of Modulated Turning

Creator:: Ozdemir, Mert
Abstract:: Modulation assistance is widely employed to improve chip management in turning. This process is also known as modulated turning. Modulated turning transforms continuous cutting into intermittent cutting by periodically disengaging the tool tip from the workpiece, resulting in the generation of short, easily managed chips. This novel method improves the...
