Aspects of Finite Element Simulation of Axi-Symmetric Hydromechanical Deep Drawing
(The American Society of Mechanical Engineers (ASME), 2001)A new approach for the Finite Element modelling of the hydromechanical deep drawing process is evaluated. In the model a Finite Difference approximation of Reynold’s equation is solved for the ... -
Die Forging Stress Determination: A Dimensional Analysis Approach
(The American Society of Mechanical Engineers (ASME), 2001)The stress provided by the forging press for manufacturing closed die forgings (forging stress) is evaluated through dimensional analysis. Five dimensionless groups, from the process variables, ... -
Finite Element Simulation of Ausforming of Austempered Ductile Iron Components
(The American Society of Mechanical Engineers (ASME), 2001)The mechanical properties of ductile iron can be improved by ausforming, that is, applying work during austempering. The resulting yield strength and ductility are comparable to those of SAE ... -
An Adaptive Statistically Based Controller for Through-Feed Centerless Grinding
(The American Society of Mechanical Engineers (ASME), 2001)The purpose of this research is to develop a statistically based controller that is “self-tuning.” High volume manufacturing processes such as through-feed centerless grinding are best controlled ... -
Analysis of Tool Oscillation and Hole Roundness Error in a Quasi-Static Model of Reaming
(The American Society of Mechanical Engineers (ASME), 2001)A quasi-static model of reaming is developed to explain oscillation of the tool during cutting and the resulting roundness errors in reamed holes. A tool with N evenly-spaced teeth often ... -
Tool Point Frequency Response Prediction for High-Speed Machining by RCSA
(The American Society of Mechanical Engineers (ASME), 2001)The implementation of high-speed machining for the manufacture of discrete parts requires accurate knowledge of the system dynamics. We describe the application of receptance coupling substructure ... -
Accurate 5-Axis Machining of Twisted Ruled Surfaces
(The American Society of Mechanical Engineers (ASME), 2001)Flank cutting can be effectively employed to machine ruled surfaces instead of traditional point cutting. In consideration of reducing discrepancies between designed and machined twisted ruled ... -
Dimensionless Parameters for Helical Compression Springs
(The American Society of Mechanical Engineers (ASME), 1960)Spring design, in many instances, is still a trial-and-error process. The underlying reason is the large number of complex variables which must be related to the allotted space which the spring ... -
Microfiltration of Polyoxyalkylene Metalworking Fluid Lubricant Additives Using Aluminum Oxide Membranes
(The American Society of Mechanical Engineers (ASME), 2001)Microfiltration is capable of reducing health hazards and environmental pollution associated with metalworking fluids (MWFs) by enabling recycling and microbial removal. This paper investigates ... -
