Abstract: An important step within the automated type synthesis process is the generation of graphical displays of proposed mechanisms which permit designers to visualize the candidates. In this paper, ...

Abstract: Modern optimal control techniques are applied to minimize the transient vibrations of uniform plates by means of one or more linear dampers. Both damper rates and locations are optimized, and ...

Abstract: In this study, gas tungsten arc welding is analyzed and modeled as a 2-input (welding current and arc length) 2-output (weld depression and width) multivariable process. Experiments under a ...

Abstract: Braced metallic tubes are used to dissipate kinetic energy in impact attenuation devices used in transportation safety applications. It is an experimentally observed fact that these braced tubes collapse asymmetrically, ...

Abstract: The effect of combined water immersion and sustained bending on the degradation response of E-glass/vinylester composites is characterized through mechanical testing (tension and short-beam-shear) and moisture uptake. It ...

Abstract: This paper investigates the relationship between drill life, the sound, and the drift forces produced by the drilling process. Tests were performed while drilling steel with 38 in. twist drills. ...

Abstract: A supervisory process control approach to machining is presented in this paper, and demonstrated by application to a drilling operation. The supervisory process control concept incorporates ...

Abstract: A statistical analysis of hole quality in drilling was performed. Using standard twist drills, holes were drilled dry in hot rolled steel. The effects of feed and speed on the hole quality ...

Abstract: The design and implementation of feed, speed, and torque controllers for drilling is discussed. Dynamic models of the feedrate drive and spindle motors were developed using experimental data and ...
