RISA Model for Bending, Torsional, and Axial Vibrations of Micro- and Macro-Drills Including Actual Drill Geometry—Part I: Model Development and Numerical Solution
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Part I of this work presents a combined one-dimensional/three-dimensional approach for obtaining a unified model for the dynamics of micro- and macro-drills. To increase the numerical efficiency ...
A Model for Bending, Torsional, and Axial Vibrations of Micro- and Macro-Drills Including Actual Drill Geometry—Part II: Model Validation and Application
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In Part II of this work, an experimental study is conducted to validate the three-dimensional (3D-ST) drill dynamics model. Modal experiments on macro- and micro-drills are performed by exciting ...
Microendmill Dynamics Including the Actual Fluted Geometry and Setup Errors—Part I: Model Development and Numerical Solution
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents an analytical model for the microendmill dynamics, including the setup errors, the axial force, the sectioned tool geometry, and the actual crosssection of the twisted fluted ...
Microendmill Dynamics Including the Actual Fluted Geometry and Setup Errors—Part II: Model Validation and Application
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents a study to validate the microendmill dynamics model derived in Part I. A laser Doppler vibrometer system that is coupled with a microscope is used to measure the natural ...
A Spectral-Tchebychev Solution for Three-Dimensional Vibrations of Parallelepipeds Under Mixed Boundary Conditions
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Vibration behavior of structures with parallelepiped shape—including beams, plates, and solids—are critical for a broad range of practical applications. In this paper we describe a new approach, ...
