Effects of Crystallographic Anistropy on Orthogonal Micromachining of Single-Crystal Aluminum
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Anisotropy of workpiece crystals has a significant effect in micromachining since the uncut chip thickness values used in micromachining are commensurate with characteristic dimensions of crystals ...
A Rate-Sensitive Plasticity-Based Model for Machining of fcc Single-Crystals—Part II: Model Calibration and Validation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: For a range of precision machining and micromachining operations, the crystallographic anisotropy plays a critical role in determining the machining forces. Part II of this work presents the ...
A Rate-Sensitive Plasticity-Based Model for Machining of Face-Centered Cubic Single-Crystals—Part I: Model Development
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: With the increased application of micromachining, including micromilling and microdrilling, the need to develop accurate models for machining at the microscale has been recognized. In particular, ...
Effect of Severe Prior Deformation on Electrical-Assisted Compression of Copper Specimens
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In electrical-assisted forming (EAF), current is passed through the material during the deformation process, which results in a decrease in the required flow stress for the material. While ...
