Single Grit Simulation of the Abrasive Machining of Wood
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The wood-grit interaction between an idealized steel grit and both dry and saturated ponderosa pine (Pinus ponderosa) is investigated for a range of grit rake angles. Regions of rubbing, ploughing ...
In-Process Tool Fracture Detection
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper investigates the feasibility of using acoustic emission (AE) signal analysis for the detection of the breakage as well as the chipping of a cutting tool during machining. Experiments ...
Characterization of Sheet Metal Forming Using Acoustic Emission
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The application of acoustic emission signal analysis for characterization of sheet metal forming operations is discussed in this paper. Two particular sheet metal forming operations are examined: ...
A Study of Burr Formation Processes Using the Finite Element Method: Part II—The Influences of Exit Angle, Rake Angle, and Backup Material on Burr Formation Processes
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Finite element models in orthogonal cutting are presented in order to examine the influences of exit angles of the workpiece, tool rake angles, and backup materials on burr formation processes ...
A Study of Burr Formation Processes Using the Finite Element Method: Part I
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A finite element model of orthogonal metal cutting including burr formation is presented. A metal-cutting simulation procedure based on a ductile failure criterion is proposed for the purpose ...
Effect of In-Plane Exit Angle and Rake Angles on Burr Height and Thickness in Face Milling Operation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Burrs formed by milling are three-dimensional in nature. Therefore the three-dimensional effects on milling burr formation in 304L stainless steel were considered. An important aspect of the ...
Modeling and Analysis of Acoustic Emission in Diamond Turning
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: To estimate the acoustic emission (AE) energy released in diamond turning, a quantitative model, which contains the energy from primary, secondary, tertiary cutting zones and the rubbing zones, ...
Finite Element Modeling of Burr Formation Process in Drilling 304 Stainless Steel
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A 3D finite element model was developed for the simulation of drilling burr formation processes of 304L stainless steel. The nonlinear thermo-elastic-plastic model simultaneously accounts for ...
A Model of Tool Fracture Generated Acoustic Emission During Machining
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents details of a study of the fundamental nature of the high amplitude acoustic emission (AE) signal generated during the complete breakage of cutting tools. A quantitative model ...
Acoustic Emission Sensing of Tool Wear in Face Milling
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Acoustic Emission (AE) signal analysis was applied to on-line sensing of tool wear in face milling. Cutting tests were conducted on a vertical milling machine. AE signals, feed and normal ...
