RISSimulation of Grain Refinement Induced by High-Speed Machining of OFHC Copper Using Cellular Automata Method
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: During high-speed machining (HSM), the microstructure of materials evolves with significant plastic deformation process under high strain rate and high temperature, which affects chip formation and material fracture ...
Plastic Strain Threshold Determination for White Layer Formation in Hard Turning of AISI 52100 Steel Using Micro-Grid Technique and Finite Element Simulations
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: White layer (WL) formation in metal cutting is generally found to have negative effects on the corrosion and fatigue life of machined components. Nowadays, the mechanism of the WL formation has not been understood very ...
Phenomenological Study of Multivariable Effects on Exit Burr Criteria During Orthogonal Cutting of AlSi Alloys Using Principal Components Analysis
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: During machining, burrs are produced along a part's edges, which can affect a final product lifetime or its efficiency. Moreover, time-consuming and expensive techniques are needed to be applied to remove such burrs. ...
New In Situ Imaging-Based Methodology to Identify the Material Constitutive Model Coefficients in Metal Cutting Process
Publisher: American Society of Mechanical Engineers (ASME)
Abstract: A great challenge of metal cutting modeling is the ability of the material constitutive model to describe the mechanical behavior of the work material under the deformation conditions that characterizes this process. In ...
Effects of Cutting Edge Radius on Surface Integrity in Machining of Nickel-Based Cast Superalloy: An In Situ Imaging Approach
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Cutting edge radius is a crucial factor affecting surface integrity during metal machining, which determines product performance. However, the exact mechanism of how the cutting edge radius affects machined surface has not ...
