Porosity and cutting forces: from macroscale to microscale machining correlations Porous metals, typically produced through powder metallurgy, represent a class of relatively new materials with wide industrial applications, lately extending into the microscale domain. Although produced in near-net shapes, most components fabricated from these materials still require some form of secondary machining. Despite the progress made in the field, relatively little is known eit... ... hiện toàn bộ

Life cycle analysis of grinding: a case study of non-cylindrical computer numerical control grinding via a unit-process life cycle inventory approach It is estimated that the industrial sector is responsible for 29% of the United States’ greenhouse gas emissions. Recent efforts have sought to reduce the carbon footprint of manufacturing activities. Research suggests that a key to further reducing industrial-based greenhouse gas emissions is to more accurately characterize the carbon footprint of manufacturing processes. Life cycle asse... ... hiện toàn bộ

Application of radial basis function neural networks in optimization of hard turning of AISI D2 cold-worked tool steel with a ceramic tool In this work, the optimization of a finish hard turning process for the machining of D2 steel with ceramic tools is carried out. With the help of replicate experimental data at 27 different cutting conditions, radial basis function neural network models are fitted for predicting the surface roughness and tool wear as functions of cutting speed, feed, and machining time. A novel method for... ... hiện toàn bộ
