Sequential Estimation of Machinability Parameters for Adaptive Optimization of Machinability Data Base Systems
(The American Society of Mechanical Engineers (ASME), 1985)Mathematical model type machinability data base systems require suitable model building procedures to estimate the model parameters. The estimation procedure should be capable of using subjective ... -
Using High-Speed Image Analysis to Estimate Trash in Cotton
(The American Society of Mechanical Engineers (ASME), 1985)Two new scanning type cotton trashmeters are being developed to indicate the amount of trash and foreign matter in lint cotton. These instruments are primarily intended to replace the current ... -
Algorithms to Deconvolve Stylus Geometry From Surface Profile Measurements
(The American Society of Mechanical Engineers (ASME), 1985)Stylus methods for measuring surface topography impose certain limits on resolving the true profile of a surface. These limits are primarily due to the finite geometric size of the stylus. In ... -
An Analytical Study of Deformation Behavior of Porous Metals in Uniaxial Tension and Compression
(The American Society of Mechanical Engineers (ASME), 1985)On the basis of an upper-bound approach, deformation behavior of porous metals is considered. A model for porous metals is employed to describe a kinematically admissible velocity field for ... -
The Ledge Tool: A New Cutting Tool Insert
(The American Society of Mechanical Engineers (ASME), 1985)The salient features of a simple, wear-tolerant cemented carbide tool are described. Results are presented for high-speed machining (3 to 5 times the conventional speeds) of titanium alloys in ... -
An Analytical Model of Cutting Dynamics. Part 1: Model Building
(The American Society of Mechanical Engineers (ASME), 1985)A mathematical model of machining chatter has been developed through an analytical approach in order to predict dynamic cutting force from steady-state cutting tests. The model is derived from ... -
An Analytical Model of Cutting Dynamics. Part 2: Verification
(The American Society of Mechanical Engineers (ASME), 1985)The dynamic force model developed in the preceding paper [1] is further examined. The analysis shows a successful prediction of the forms of stability boundary over a wide range of cutting ... -
Nondestructive Assessments of Residual Stresses in Railroad Wheel Rim by Acoustoelasticity
(The American Society of Mechanical Engineers (ASME), 1985)Residual stress in the rim of railroad solid wheel was measured nondestructively by an acoustoelasticity method which makes use of the birefringent effect. The acoustic anisotropy is a fractional ... -
Influence of Low Temperature Thermomechanical Treatment on Some Properties of High Alloy Tool Steels
(The American Society of Mechanical Engineers (ASME), 1985)The modification of mechanical properties (maximum bending strength and deflection, hardness and impact strength) of tool steels whose primary alloying elements are either chromium, tungsten, ... -
Principles of Dust Removal in Gin Machinery: Theoretical and Measured
(The American Society of Mechanical Engineers (ASME), 1985)Some textile mill workers develop byssinosis as a result of cotton dust. A wet extraction process can be used to remove most of the respirable dust but the quality of the yarn is lowered. ... -
Studies on Temperature of Abrasive Grains in Grinding—Application of Infrared Radiation Pyrometer
(The American Society of Mechanical Engineers (ASME), 1985)The temperature of cutting grains on wheel surface was measured by means of a new method, in which an optical fiber accepts the infrared flux radiated from the cutting grains and transmits ... -
Cutting Dynamics Identification by Dynamic Data System (DDS) Modeling Approach
(The American Society of Mechanical Engineers (ASME), 1985)The dynamics of the cutting process have been conventionally characterized in terms of the Dynamic Cutting Force Coefficients (DCFC) which represent its transfer characteristics at discrete ... -
An Arbitrarily Inclined Triangular UBET Element and Its Application to Combined Forging
