Generation of deformation-induced martensite when cryogenic turning various batches of the metastable austenitic steel AISI 347
Production Engineering - Tập 13 - Trang 343-350 - 2019
Cryogenic turning of metastable austenitic steels allows for a surface layer hardening integrated into the machining process, which renders a separate hardening process obsolete. This surface layer hardening is the result of a superposition of strain hardening mechanisms and deformation-induced phase transformation from austenite to martensite. The activation energy required for the latter depends...... hiện toàn bộ
General remarks on the entropy-inspired MCAT (manufacturing complexity assessment tool) model to assess product assembly complexity
Production Engineering - Tập 17 - Trang 815-827 - 2023
Assembly complexity assessment is a widely addressed topic in manufacturing. Several studies proved the correlation between assembly complexity and the occurrence of defects, thus justifying this increasing attention. A measure of complexity provides control over quality costs and performances. Over the years, many methods have been proposed to provide an objective measure of complexity. One of th...... hiện toàn bộ
Open control systems: state of the art
Production Engineering - Tập 4 - Trang 247-254 - 2010
Within the European initiative OSACA (Open System Architecture for Controls with Automation Systems) a company-spanning open control architecture has been developed as of 1992. Since then the development of open control systems has continued until today. In 2008 a study was carried out with the objective to verify the results of 15 years of work for open control systems in Europe. It ought to iden...... hiện toàn bộ
Deep learning-based classification of production defects in automated-fiber-placement processes
Production Engineering - Tập 13 - Trang 501-509 - 2019
This paper presents a deep learning-based approach for the detection and classification of production defects that complements an existing thermographic online monitoring system for Automated-Fiber-Placement (AFP) processes. The detection and classification procedure is performed in two stages. In the first stage, the system monitors each tow individually and classifies its process status. Further...... hiện toàn bộ
Method for optimizing the cooling design of hot stamping tools
Production Engineering - Tập 1 Số 2 - Trang 149-155 - 2007
Estimating the operation time of flexible surface mount placement machines
Production Engineering - Tập 6 - Trang 319-328 - 2012
Gantry type component placement machines are widely used in electronics industry due to their accuracy, speed and flexibility. In order to make optimal plans of their usage one has to know the manufacturing time of a given component placement work before the actual processing. This presupposes the use of a reliable machine simulator. In the present article, discrete-event simulation is applied to ...... hiện toàn bộ
Improvement of dry EDM process characteristics using artificial soft computing methodologies
Production Engineering - Tập 6 Số 4-5 - Trang 493-504 - 2012
Paradigm change: small machine tools for small workpieces
Production Engineering - Tập 7 - Trang 465-468 - 2013
To overcome current limitations in micro manufacturing a new approach instead of evolutionary small step progress has to take place. Applying small machine tools to manufacture small workpieces allows for a leap of improvements enabled by the small size itself. This miniaturization in comparison to simply down-scaling current concepts qualifies the use of materials and technologies commonly not fo...... hiện toàn bộ
