Synthesis of Immiscible Alloys by the Mixalloying Process
(The American Society of Mechanical Engineers (ASME), 1989)Dispersed-phase microstructures of the immiscible Pb-Zn, Pb-Zn-Sn and Pb-Al alloys were produced by the Mixalloying Process [1] . The particle size was found to follow the log-normal statistical ... -
Motion Control of Manipulators with Closed-Form Inverse Solutions Near Wrist Singularities
(The American Society of Mechanical Engineers (ASME), 1989)Two algorithms, the degenerate axis and iterative methods, are developed for the motion control of manipulators with closed-form solutions in the neighborhood of singularities. These two methods ... -
A New Approach of Formulating the Transfer Function for Dynamic Cutting Processes
(The American Society of Mechanical Engineers (ASME), 1989)The dynamics of a cutting process are very complex in nature. It involves not only the changes of plastic state in the intensive deformation zone but also the elastic behavior of work material ... -
Model Reference Adaptive Force Control in Milling
(The American Society of Mechanical Engineers (ASME), 1989)This paper describes the design and implementation of a Model Reference Adaptive Controller (MRAC) for force control in milling. First, previous work in this area is discussed. Results from ... -
Metal Machining With High-Pressure Water-Jet Cooling Assistance—A New Possibility
(The American Society of Mechanical Engineers (ASME), 1989)Metal machining is one of the fundamental manufacturing processes. The principal cost of shaping metal parts is generated both in the work involved in shearing metal from the original stock, ... -
Effects of Superheat and Volume Fraction in the Mixalloying Process
(The American Society of Mechanical Engineers (ASME), 1989)Dispersed-phase microstructures of Pb-Zn, Pb-Zn-Sn, and Pb-Al immiscible alloys were produced by the Mixalloying process. The superheat and the volume fraction of the impinging metal jets were ... -
