Reports of other STCs and CWGs on items of interest to STC-F

The STC-S envoy, Professor Lukasz Madej, gave an update from STC-S. Discussions on new regulations and the keynote papers regarding the number of authors were made. Four CWGs are active: ‘Composite materials parts manufacturing’, ‘Self-optimizing machining systems’, ‘Urban factories production in cities’ and ‘Emerging fields of technology: Additive Manufacturing’. The CWG on composite materials was disbanded in February, 2018.

Keynotes 

(a) 2018 Keynote – discussion of final paper and draft of powerpoint presentation
An outline of the presentation was given by Professor D.Y. Yang. The following comments were made.

(b) 2019 Keynote – progress report
Professors Volk and Groche reported the progress of the keynote ‘Process Limit in Metal Forming’. The title has been changed since the Lugano meeting. The following comments were made after the presentation.

(c) 2020 Keynote
The 2020 keynote ‘Damage in Metal Forming: Mechanisms, Origin, Effects & Control’ was briefly presented by Professor Tekkaya. The following comments were made.

Open discussion and brainstorming on themes and topics for 2020 Keynote

 After the brainstorming session, 22 topics of interest were summarized. A decision on the topic will be made in the next STC-F meeting on August 24, 2018.
After a brief presentation of the Chair on the past keynote STC-F topics, a typical time line, and the explanation of how the brainstorming session should work, 6 groups were formed to generate the possible candidates of topics in 2020 keynotes.

Short presentations on 2020 keynote ’ Damage in Metal Forming’

One invited presentation was given by Professor Bouchard and eight short presentations related to 2020 keynote were made.

CIRP Dictionary / CIRPedia / CIRP JMST

 CIRP Dictionary: Dictionary of Production Engineering, Vol. I/1 and Vol. I/2 “Forming”:
The forming dictionaries for the three languages German, English, and French have been published and are available as books as well as online on the platform SpringerLink.
CIRPEdia: (Section Forming): Three essays are under review, one essay is under revision and two essays are in preparation.
CIRP Journal of Manufacturing Science and Technology
In the first six months of 2018 we had six more submissions, two of which are still under review, two were rejected, and for the last two, the authors were asked to make revisions.

Interaction with other STCs

 The chair summarized the discussions in the cross-STC meeting.

 Prof. Lukasz Madej reported that one of the future keynotes from STC-S on ‘Surface defects’ will be interesting for STC-F. Also, there were a lot of discussions on collaborations with other STCs.

 The Chair proposes more interactions with other STCs. We need to look at how to bring the best ideas and most innovative activities to STC-F. This issue may be on the agenda in February.

Keynotes 

Progress report and discussion on the 2019 paper on “Process Limit in Metal Forming” by Prof. Volk and Prof. Groche 
An outline of the presentation was given by Prof. P. Groche and Prof. W. Volk.

Progress report and discussion on the 2020 STC-F keynote ‘Damage in Metal Forming: Mechanisms, Origin, Effects & Control’ by Prof. Tekkaya
An outline of the presentation was given by Prof. A. E. Tekkaya.

Presentation and selection of 2021 keynote paper: ideas and discussion
The following proposals on the 2021 keynote have been presented.
”Forming of new materials II (sandwich materials, mixed materials, composites, non-metallic materials)” by Prof. Bruschi
This keynote will discuss metal and non-metallic materials such as metals with composites and mixed materials, and sandwich materials. In other words, the proposed keynote discusses forming-based multi-materials.

 ”Simulation of metal forming processes (multi-scale, springback)” by Dr. Mihaela Banu and Prof. J. Yanagimoto
This keynote intends to forecast the contribution of metal forming simulations to upcoming forming processes – from the micro- to macroscale - in the factories of the future (Industry 4.0), and reinforce the role of simulations as computational (virtual) experiments and tools for the high-fidelity numerical visualization and quantification of unknown and un-measurable phenomena in formed components and their assembly.

 In the on-line vote after the discussion, the first proposal ”Forming of new materials II (sandwich materials, mixed materials, composites, non-metallic materials)” received 26 ballots and the second proposal received 17. The first proposal was selected as the keynote paper for year 2021. The keynote on simulation can be discussed as a candidate cross-STC keynote.

Short presentations

One invited presentation “Effect of ductile damage accumulation on cold formability and edge crack sensitivity of multiphase sheet steels” was presented by Professor S. Münstermann (Steel Institute IEHK, RWTH Aachen University). Six presentations were given. 

Special session

Professor Marciniak’s special session to celebrate his 100th birthday was held from 2pm to 4pm at Nishiki room on the 4th floor.
