RISDerived Nodes Approach for Improving Accuracy of Machining Stability Prediction
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Machining process dynamics can be described by state-space delayed differential equations (DDEs). To numerically predict the process stability, diverse piecewise polynomial interpolation is often utilized to discretize the ...
Active Chatter Suppression in Low Immersion Intermittent Milling Process
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Chatter in low immersion milling behaves differently from that in full immersion milling, mainly because of the non-negligible time-variant dynamics and the occurrence of period doubling bifurcation. The intermittent and ...
Minimax Optimization Strategy for Process Parameters Planning: Toward Interference-Free Between Tool and Flexible Workpiece in Milling Process
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In milling of flexible workpieces, like axial-flow compressor impellers with thin-wall blades and deep channels, interference occurrence between workpiece and tool shaft is a great adverse issue. Even though interference ...
Improving Parameterization of Entrainment Rate for Shallow Convection with Aircraft Measurements and Large-Eddy Simulation
Publisher: American Meteorological Society
Abstract: his work examines the relationships of entrainment rate to vertical velocity, buoyancy, and turbulent dissipation rate by applying stepwise principal component regression to observational data from shallow cumulus clouds ...
