RISSimplified Improvement of Higher Order Extended Bulk Flow Analysis Specialized for Derivation of Rotordynamic Coefficients of the Annular Plain Seal With Large Static Eccentricity
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Rotordynamic (RD) fluid force of turbomachinery is known as one of the causes of the shaft vibration problem. Bulk flow analysis is the analytical method of RD fluid force, and it is widely used in design stage. Conventional ...
The Mechanism of Chatter Vibration in a Spindle-Workpiece System: Part 1—Properties of Self-Excited Chatter Vibration in Spindle-Workpiece System
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The elimination of chatter vibration is important to improve cutting accuracy and to improve productivity of the cutting operation. In this study, the characteristics of the primary and regenerative ...
Relationships Between Cutting Force Variations and Cutting Factors in Plain Milling Operations. Part 2: Plain Milling With a Multi-Toothed Helical Cutter
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Cutting force variation in plain milling with a multi-toothed helical cutter can be obtained by calculation on the basis of the measured cutting force variation in plain milling with a ...
Relationships Between Cutting Force Variations and Cutting Factors in Plain Milling Operations. Part 1: Plain Milling With a Single-Toothed Helical Cutter
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In plain milling operations with a single-toothed helical cutter, three components of cutting force are measured simultaneously and continuously corresponding to the varying cross-sectional area ...
The Mechanism of Chatter Vibration in a Spindle-Workpiece System: Part 2—Characteristics of Dynamic Cutting Force and Vibration Energy
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The cutting force acting in the dynamic state of a lathe spindle-workpiece system is affected by the dynamic variations of cutting depth, cutting velocity, and rake angle. In this study, the ...
The Mechanism of Chatter Vibration in a Spindle-Workpiece System: Part 3—Analytical Considerations
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Chatter vibration occurring in the spindle-workpiece system of a lathe is treated theoretically, considering the phase lag of cutting force and chatter marks, the dynamic variation effects on ...
