Abstract: To eliminate health and environmental problems caused by using conventional cutting fluid in the machining industry, a new economical and practical approach to cryogenic machining technology was ...

Abstract: Ductile materials such as AISI1008 low carbon steel characteristically exhibit poor chip breaking in conventional machining practices. This paper presents an environmentally clean cryogenic machining ...

Abstract: A preemptive diagnostic system has been developed to detect minor machine failures before machine breakdown for a computer controlled robotic drilling end-effector. By using the Dynamic Data ...

Abstract: The characteristics of nine common drill failure modes have been analyzed. To facilitate detecting and diagnosing these failure modes, a multi-sensor approach is developed. Based on the dynamic ...

Abstract: In this study, an anisotropic thermal-elastic-plastic (TEP) constitutive model is developed for soft clays. Two yield surfaces, namely the current yield surface and reference yield surface, are adopted to characterize the ...

Abstract: This paper reports a field study on the downdrag and dragload of two pairs of bored piles installed in consolidating ground in the Zhejiang coastal area, China. During and after the construction of a 2.5-m-high embankment, ...
