Rapid vision-based dimensional precision inspection of mesoscale artefacts
Proceedings of the Institution of Mechanical Engineers, Part B: Journal of Engineering Manufacture - Tập 221 Số 4 - Trang 659-672 - 2007
Samir Mekid, Heeburm Ryu
This paper describes the investigation and implementation of image processing techniques converted into precision measurement techniques for feature inspection of mesoscale artefacts. The method resulted in a rapid, low-cost, and precise inspection technique. Better performances are obtained with the combination of the pixel uncertainty edge detector and the subpixel uncertainty detector along wit... hiện toàn bộ
Machine tool optimization strategies for ecologic and economic efficiency
Proceedings of the Institution of Mechanical Engineers, Part B: Journal of Engineering Manufacture - Tập 227 Số 1 - Trang 54-61 - 2013
Adam Gontarz, F. Hänni, Lukáš Weiss, Konrad Wegener
Optimization activities in manufacturing must be addressed in the multifaceted context that combines economic, social and environmental goals. Research activities of today not only strive to cope with the legislative pressure of the Directive of the European Parliament on Energy Using Products but also strive for economic advantages for the machine tool user by investigating and applying suitable ... hiện toàn bộ
Ultra-high-speed combined machining of electrical discharge machining and arc machining
Proceedings of the Institution of Mechanical Engineers, Part B: Journal of Engineering Manufacture - Tập 228 Số 5 - Trang 663-672 - 2014
Fei Wang, Liu Y, Zemin Tang, Renjie Ji, Yanzhen Zhang, Yang Shen
In this study, a new kind of ultra-high-speed combined machining of electrical discharge machining and arc machining was developed. A rotating graphite electrode and a workpiece were connected to the negative and positive poles of the power supply, which consisted of a pulse generator and direct current power. Efficient electrode injection flushing and side flushing yielded a noncontinuous arc and... hiện toàn bộ
Evaluating errors in screw rotor machining by tool to rotor transformation
Proceedings of the Institution of Mechanical Engineers, Part B: Journal of Engineering Manufacture - Tập 220 Số 10 - Trang 1589-1596 - 2006
Nikola Stošić
Screw compressor rotors are machined mainly by form grinding or milling tools. The precision requirements imposed upon them are today so demanding that the tool is allowed only limited wear and must be well set in the machine. It is therefore important to be able to quantify the tool set errors as well as to compensate for tool deformation and wear. Tool to rotor transformation is applied here to ... hiện toàn bộ
Optimum Cutting Conditions for Turned Components
Proceedings of the Institution of Mechanical Engineers, Part B: Journal of Engineering Manufacture - Tập 206 Số 1 - Trang 15-31 - 1992
J.A. Arsecularatne, S. Hinduja, G. Barrow
This paper describes the procedures used in a technologically orientated numerically controlled (NC-) system to determine the optimum culling conditions automatically for turning, drilling, grooving, threading and parting-off operations. In rough turning, the optimum depth and feed combination is determined using a direct search procedure on the allowable depth/feed region for chip control. The sy... hiện toàn bộ
Prediction of Cutting Forces and Built-Up Edge Formation Conditions in Machining With Oblique Nose Radius Tools
Proceedings of the Institution of Mechanical Engineers, Part B: Journal of Engineering Manufacture - Tập 210 Số 5 - Trang 457-469 - 1996
J.A. Arsecularatne, R.F. Fowle, P. Mathew, P.L.B. Oxley
A semi-empirical machining theory is described for predicting cutting forces and temperatures for oblique nose radius tools from cutting conditions and a knowledge of work material flow stress and thermal properties. Predictions are made for a range of cutting speeds and tool geometries. It is shown how the cutting conditions giving a built-up edge can be determined from the predicted cutting temp... hiện toàn bộ
Prediction of Chip Flow Direction and Cutting Forces in Oblique Machining with Nose Radius Tools
Proceedings of the Institution of Mechanical Engineers, Part B: Journal of Engineering Manufacture - 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
Review on powder-bed laser additive manufacturing of Inconel 718 parts
Proceedings of the Institution of Mechanical Engineers, Part B: Journal of Engineering Manufacture - 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
Life cycle analysis of grinding: a case study of non-cylindrical computer numerical control grinding via a unit-process life cycle inventory approach
Proceedings of the Institution of Mechanical Engineers, Part B: Journal of Engineering Manufacture - Tập 226 Số 10 - Trang 1604-1611 - 2012
Vance R. Murray, Fu Zhao, John W. Sutherland
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 assessment is... hiện toàn bộ
Artificial neural network–based and response surface methodology–based predictive models for material removal rate and surface roughness during electro-discharge diamond grinding of Inconel 718
Proceedings of the Institution of Mechanical Engineers, Part B: Journal of Engineering Manufacture - Tập 230 Số 11 - Trang 2082-2091 - 2016
Deepak Rajendra Unune, Harlal Singh Mali
Hybrid machining processes growing popularity in the processing of difficult-to-cut materials due to their distinct merits over individual machining processes attributed by an amalgamation of two or more machining mechanisms simultaneously. This research study deals with the response surface methodology and artificial neural network with backpropagation algorithm–based mathematical modeling of ele... hiện toàn bộ
