RISSuppression of Chatter Vibration in Drilling
Publisher: The American Society of Mechanical Engineers (ASME)
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. ...
Chucking Performance of a Wedge-Type Power Chuck
Publisher: The American Society of Mechanical Engineers (ASME)
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 ...
Cutting Performance of a Cemented Carbide Drill with Three Cutting Edges
Publisher: The American Society of Mechanical Engineers (ASME)
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, ...
On the Cause of Regenerative Chatter Due to Workpiece Deflection
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The cause and the mechanism of regenerative chatter vibrations due to the deflection of workpiece occurring in machining metals are investigated experimentally. The regenerative chatter vibration ...
Static and Dynamic Analysis of Hydraulic Copying System Using Throttling Valve
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The effect of dimension parameters of hydraulic copying control system using throttling valve on the copying accuracy is investigated from two points of view for good design of the system. One ...
Whirling Vibration in Drilling. Part 3: Vibration Analysis in Drilling Workpiece with a Pilot Hole
Publisher: The American Society of Mechanical Engineers (ASME)
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 ...
Chatter Vibration in Drilling
Publisher: The American Society of Mechanical Engineers (ASME)
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, ...
Whirling Vibration in Drilling. Part 2: Influence of Drill Geometries, Particularly of the Drill Flank, on the Initiation of Vibration
Publisher: The American Society of Mechanical Engineers (ASME)
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 ...
Whirling Vibration in Drilling. Part 1: Cause of Vibration and Role of Chisel Edge
Publisher: The American Society of Mechanical Engineers (ASME)
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 ...
Damping Capacity of Turning Tools, Part 1: Effect of Clamping Conditions and Optimum Clamping Load
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Damping capacity greatly affects the dynamic rigidity of a machine tool system. This paper deals with the damping capacity of turning tools. Damping capacity is measured as a function of ...
