A Product-Service System (PSS) is an integrated combination of products and
services. This Western concept embraces a service-led competitive strategy,
environmental sustainability, and the basis to differentiate from competitors
who simply offer lower priced products. This paper aims to report the
state-of-the-art of PSS research by presenting a clinical review of literature
currently available o... hiện toàn bộ
An empirical model for predicting energy consumption of manufacturing processes: a case of turning process Tập 225 Số 9 - Trang 1636-1646 - 2011
Wen Li, Sami Kara
Optimizing the energy efficiency of processes has become a priority in the
manufacturing sector; driven by soaring energy costs and the environmental
impact caused by high energy consumption levels. The energy consumed by a
machine tool performing a turning process consists of not only the energy
required by the tool tip for material removal but also the energy used for
auxiliary functions. Tradit... hiện toàn bộ
Review on powder-bed laser additive manufacturing of Inconel 718 parts Tập 231 Số 11 - Trang 1890-1903 - 2017
Xiaoqing Wang, Xue Gong, Kevin Chou
This study presents a thorough literature review on the powder-bed laser
additive manufacturing processes such as selective laser melting of Inconel 718
parts. This article first introduces the general aspects of powder-bed laser
additive manufacturing and then discusses the unique characteristics and
advantages of selective laser melting. The bulk of this study includes extensive
discussions of m... hiện toàn bộ
A benchmark study on rapid prototyping processes and machines: Quantitative comparisons of mechanical properties, accuracy, roughness, speed, and material cost Tập 222 Số 2 - Trang 201-215 - 2008
G D Kim, Young-Jin Oh
Various kinds of layer manufacturing process are available, such as stereo
lithography (SL), fused deposition modelling (FDM), Poly-jet, selective laser
sintering (SLS), three-dimensional printing (3DP), laminated object
manufacturing (LOM), etc. The object of the current study is the quantifications
and comparisons of the processes' characteristics using representative apparatus

Analysis and estimation of energy consumption for numerical control machining Tập 226 Số 2 - Trang 255-266 - 2012
Yan He, F Liu, Tao Wu, F-P Zhong, Bin Peng
Understanding and estimating the energy consumed by machining are essential
tasks as the energy consumption during machining is responsible for a
substantial part of the environmental burden in manufacturing industry. Facing
the problem, the present paper aims to analyse the correlation between numerical
control (NC) codes and energy-consuming components of machine tools, and to
propose a practica... hiện toàn bộ
A mechanical model for predicting critical thrust forces in drilling composite laminates Tập 215 Số 2 - Trang 135-146 - 2001
L-B Zhang, Lijing Wang, XY Liu
Among the various forms of material damage, delamination due to drilling is one
of the major concerns in machining a composite laminate. The thrust force has
been cited as the primary cause of the delamination. The analysis for
multidirectional composite laminates is based on linear elastic fracture
mechanics (LEFM), classical bending plate theory and the mechanics of
composites. This paper presen... hiện toàn bộ
Prediction of Chip Flow Direction and Cutting Forces in Oblique Machining with Nose Radius Tools Tập 209 Số 4 - Trang 305-315 - 1995
J.A. Arsecularatne, P. Mathew, P.L.B. Oxley
A method is described for calculating the chip flow direction in terms of the
tool cutting edge geometry and the cutting conditions, namely feed and depth of
cut. By defining an equivalent cutting edge based on the chip flow direction it
is then shown how cutting forces can be predicted given the work material's flow
stress and thermal properties. A comparison between experimental results
obtained... hiện toàn bộ
Porosity and cutting forces: from macroscale to microscale machining correlations Tập 225 Số 5 - Trang 619-630 - 2011
O. Remus Tutunea‐Fatan, M. Abolghasemi Fakhri, Evgueni V. Bordatchev
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
either on th... hiện toàn bộ
New algorithm for calibration of instantaneous cutting-force coefficients and radial run-out parameters in flat end milling Tập 221 Số 6 - Trang 1007-1019 - 2007
Min Wan, W H Zhang, Guojin Tan, Guohua Qin
It is well recognized that the cutter run-out appearing in the milling process
will cause an uneven redistribution of the instantaneous uncut chip thickness
through the cutter flutes and thereby will generate an irregular distribution of
the cutting forces in different tooth periods. This work aims to develop a new
approach able to identify the cutter radial run-out and cutting-force
coefficients ... hiện toàn bộ
