RISMeasurement Scheme Synthesis in Multi-Station Machining Systems
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Different sets of measurements carry different amounts of information about the root causes of quality problems in machining. The selection of measurements in multi-station machining systems is ...
A Method for Measuring the Temperature Distribution Along the Cutting Edges of a Drill
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A drill-foil thermocouple system is developed for measuring the temperature distribution along the cutting edges of a drill. The system is simple to implement, and it does not suffer the ...
A Model for Predicting the Heat Flow into the Workpiece in Dry Drilling
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A model is developed for predicting the heat that flows into the workpiece during dry drilling processes. The model can be applied to any drill of known geometry. The measured drilling thrust ...
Experimental Study of Tangential Micro Deflection of Interface of Machined Surfaces
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper studies the characteristics of micro tangential deflection of the interface of mating machined surfaces subjected to normal and tangential forces. Experimental results show that contact ...
Constraints Based Nonrigid Registration for 2D Blade Profile Reconstruction in Reverse Engineering
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In reverse engineering, 2D profile curve reconstruction based on cross-sectional points is a very crucial step for surface reconstruction such as lofting surface, swept surface, translational ...
Prediction of Coolant Pressure and Volume Flow Rate in the Gundrilling Process
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Coolant volume flow rate and pressure critically affect the chip evacuation in the gundrilling process. A predictive fluid model was developed to estimate coolant volume flow rate and pressure, ...
Dimensional Errors of Fixtures, Locating and Measurement Datum Features in the Stream of Variation Modeling in Machining
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Machining processes are usually multi-station processes involving a large number of operations and several locating datum changes. Machining errors are thus introduced, transformed and accumulated ...
Modeling and Calibration of a Structured-light Optical CMM via Skewed Frame Representation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A new tetrahedron-target-based approach is presented for the extrinsic calibration of a non-contact “light-striping” (structured light) optical coordinate measuring machine (CMM). The procedure makes ...
B-Spline Wavelet-Based Multiresolution Analysis of Surface Texture in End-Milling of Aluminum
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Modern manufacturing requires close monitoring by correlating finer frequency regimes of the surface texture to process parameters. This paper presents a study of B-spline wavelet-based multiresolution ...
Adaptive Product, Process and Tooling Design Strategy for Optimal Dimensional Quality of Automotive Body Assemblies
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Research investigations have shown that the dimensional quality is deeply rooted in the whole process of the product development, from product, process and tooling design, the tooling manufacturing ...
