Algorithm for Spatial Straightness Evaluation Using Theories of Linear Complex Chebyshev Approximation and Semi-infinite Linear Programming
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents a novel methodology for evaluating spatial straightness error based on the minimum zone criterion. Spatial straightness evaluation is formulated as a linear complex Chebyshev ...
Two-Sided Quadratic Model for Workpiece Fixturing Analysis
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents a novel model for workpiece positioning analysis. Existing fixturing models may underestimate the positioning error due to neglect of the curvature of one or both contacting ...
Analytical Expression of the Swept Surface of a Rotary Cutter Using the Envelope Theory of Sphere Congruence
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Based on the observation that many surfaces of revolution can be treated as a canal surface, i.e., the envelope surface of a one-parameter family of spheres, the analytical expressions of the ...
Optimal Design of Measurement Point Layout for Workpiece Localization
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents a methodology for the optimal design of the measurement point layout for 3D workpiece localization in the presence of part surface errors and measurement errors. A number ...
On a Numerical Method for Simultaneous Prediction of Stability and Surface Location Error in Low Radial Immersion Milling
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This brief proposes a numerical approach for simultaneous prediction of stability lobe diagrams and surface location error in low radial immersion milling based on the direct integration scheme ...
Synchronous Averaging of Time-Frequency Distribution With Application to Machine Condition Monitoring
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A novel signal analysis technique capable of detecting periodic bursts of exponentially decaying oscillation from noisy discrete-time observations is presented. The time-frequency distribution of ...
Numerical Integration Method for Prediction of Milling Stability
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents a numerical scheme to predict the milling stability based on the integral equation and numerical integration formulas. First, the milling dynamics taking the regenerative ...
A Distance Function Based Approach for Localization and Profile Error Evaluation of Complex Surface
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents a unified framework for best-fitting of complex rigid surface to measured 3-D coordinate data by adjusting its location (position/orientation). For a point expressed in the ...
Geometry of Signed Point-to-Surface Distance Function and Its Application to Surface Approximation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents a unified framework for computing a surface to approximate a target shape defined by discrete data points. A signed point-to-surface distance function is defined, and its ...
