Abstract: In this study, from the viewpoint of suppressing chatter vibration in drilling, the effects of cutting conditions on the initiation boundary of chatter vibration were investigated experimentally. ...

Abstract: In order to improve the chucking performance of a wedge-type power chuck with three top jaws, bending tests, chucking accuracy tests, and cutting tests in the chuck-work system were performed ...

Abstract: In this paper, an investigation of the cutting performance of a cemented carbide drill with three cutting edges is reported. Drilling tests were performed in which the eccentricity, straightness, ...

Abstract: The whirling vibration of the drill when beginning the drilling of a workpiece with a pilot hole, is theoretically examined. It becomes clear that the whirling is a regenerative chatter vibration ...

Abstract: Chatter vibration of long drills has been investigated using several drills with different overhang lengths and special drills with different pieces of additional mass. The frequency, amplitude, ...

Abstract: The development of whirling vibration is observed by using drills with various web thicknesses, point angles, relief angles, and various helix angles in order to investigate the effect of drill ...

Abstract: The whirling vibration of the drill in the beginning of the drilling operation is experimentally investigated. Special attention is paid to how vibration develops as the drill proceeds into the ...

Abstract: This paper presents an experimental investigation of the contact rigidity between a turning tool shank and tool post. The contact rigidity is influenced by the flexural rigidity of tool shank, ...

Abstract: The primary chatter vibration of turning tools is investigated experimentally. The vertical displacement of the turning tool and the fluctuating cutting force in the primary chatter vibration are ...

Abstract: First, the development of the chatter vibration is observed using several turning tools having various cutting edge configurations and in the conditions in which there are different levels of ...
