Proposal of “Curved-Profile Wiper Turning” for efficient, stable, and smooth finishing

Abstract This paper presents an efficient, stable, and smooth turning method for curved-profile workpieces. Conventional wiper tools can achieve high efficiency, high chatter stability, and smooth surfaces at the same time only for linear-profile workpieces. A novel method is proposed, which extends the wiper tool concept to the curved-profile turning. In this method, a suitable wiper-edge radius is chosen for better smoothness, and the tool posture is controlled for higher regenerative chatter stability. Curved-profile turning experiments are conducted, and high efficiency, high chatter stability, and smooth surfaces are achieved at the same time by the proposed method.
