RISAn Adaptive Methodology for Machine Tool Error Correction
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: An adaptive methodology for machine tool error correction is presented in this paper. The estimated errors resulting from the proposed methodology could be used to adjust the depth of cut on ...
An Innovative Approach to Increase the Accuracy of Multi-Axis Machines for Process-Intermittent Inspection
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A method for enhancing the effectiveness and robustness of process-intermittent inspection is presented. The method is developed first using mathematical models and measurements closely related to ...
Improving Chucking Accuracy and Repeatability by Reducing Kinematic Redundancy
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, the effect of kinematic redundancy on chucking, especially, on the positioning accuracy of a cylindrical workpiece was investigated. No previous research on the effect of kinematic ...
3D FEA Modeling of Hard Turning
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A practical explicit 3D finite element analysis model has been developed and implemented to analyze turning hardened AISI 52100 steels using a PCBN cutting tool. The finite element analysis ...
Mechanical Properties of Hardened AISI 52100 Steel in Hard Machining Processes
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper provides an approach using tensile tests at elevated temperatures to estimate mechanical properties of the work material for both elastic and plastic deformations in a broad range ...
The Mechanical State of the Sublayer of a Surface Generated by Chip-Removal Process—Part 1: Cutting With a Sharp Tool
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The mechanical state of a machined component surface was studied and three quantitative measures, namely, apparent strain energy density, strain hardening index, and residual stress distribution ...
The Mechanical State of the Sublayer of a Surface Generated by Chip-Removal Process—Part 2: Cutting With a Tool With Flank Wear
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The mechanical state of a surface machined with a tool having flank wear is discussed in this paper, which is the second in a sequence of two papers, the first dealing with sharp tools. A ...
Variables Governing Patterns of Mechanical Residual Stress in a Machined Surface
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Mechanical residual stress in a machined surface was studied experimentally. Structural change was eliminated by machining low-carbon steel under selected conditions. The shape of the cutting edge ...
An Analytical Model of Cutting Dynamics. Part 1: Model Building
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A mathematical model of machining chatter has been developed through an analytical approach in order to predict dynamic cutting force from steady-state cutting tests. The model is derived from ...
An Analytical Model of Cutting Dynamics. Part 2: Verification
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The dynamic force model developed in the preceding paper [1] is further examined. The analysis shows a successful prediction of the forms of stability boundary over a wide range of cutting ...
