Presentation: Chasing nanometres - development of high-performance
position encoders for accurate motion control in manufacturing
Name: Dr Ian Carpenter
Affiliation: Renishaw plc, New Mills, Wotton-under-Edge,
Gloucestershire, GL12 8JR, United Kingdom
Abstract:

Manufacturing parts to tolerances of only a few microns has been achievable for several centuries, driven by high value but low volume applications such as fabrication of optical lens and gratings, and bespoke timepieces. The emerging demand for interchangeable parts for mass manufacture of complex devices, such as watches and cars, has fostered innovation in process design and control which continues to this day. Low cost but high-performance motion control has been facilitated by high-performance position encoders.

 

This presentation will describe the development of high-performance position encoder technologies over the last few decades. Ever increasing performance requirements for compact measurement systems that can deliver reliable, stable and accurate position measurement in a variety of environments and for a low cost have led to advances in miniature optics, signal processing and interpolation, accurate and reliable scale manufacture, and automated assembly. Future encoder development opportunities continue to emerge, such as multi-sensor devices for Industry 4.0 integration, custom encoders for highly specific applications such as co-operative robots, and extremely agile position encoding to meet electronic manufacturing throughput targets.

Abstract: TBC
Biography:
Since January 1, 2004, Prof. Dr.-Ing. Christian Brecher is the Ordinary Professor for Machine Tools at the Laboratory for Machine Tools and Production Engineering (WZL) of the RWTH Aachen as well as the Director of the Department for Production Machines at the Fraunhofer Institute for Production Technology IPT. Further, he is CEO of the Cluster of Excellence “Integrative Production Technology for High-Wage Countries” that is funded by the German Research Foundation (DFG). Together with his colleague Prof. Hopmann he is also responsible for the Aachen Center for Integrative Lightweight Production (AZL) since 2012.
 
After finishing his academic studies in mechanical engineering, he started his professional career first as a research assistant and later as a team leader in the department for machine investigation and evaluation at the WZL. From 1999 to April 2001, he was responsible for the department of machine tools in his capacity as a Senior Engineer. After a short spell as a consultant in the aviation industry, Professor Brecher was appointed in August 2001 as the Director for Development at the DS Technologie Werkzeugmaschinenbau GmbH, Mönchengladbach, where he was responsible for construction and development until December 2003.
 
Professor Brecher has received numerous honours and awards including the Springorum Commemorative Coin, the Borchers Medal of the RWTH Aachen, the Scholarship Award of the Association of German Tool Manufacturers (Verein Deutscher Werkzeugmaschinenfabriken VDW) and the Otto Kienzle Memorial Coin of the Scientific Society for Production Technology (Wissenschaftliche Gesellschaft für Produktionstechnik WGP).
 
Currently he is chairman of the scientific group for machines of CIRP, the International Academy for Production Engineering and Vice director of Fraunhofer Institute for Production Technology.

Presentation: Polymer physics in nanoscale cutting: Opportunities for
improved control in nano-manufacturing?
Name: Professor Kristofer Gamstedt
Affiliation: Uppsala University, The Ångström laboratory, Uppsala, Sweden

Biography:

Kristofer Gamstedt received a M.Sc. degree in Applied Physics and Electrical Engineering from Linköping University, Sweden, in 1993, and a Ph.D. degree in Polymer Engineering from Luleå University of Technology, Sweden, in 1998. He is currently professor at the Department of Engineering Sciences at Uppsala University, Sweden, where he is the head of the Division of Applied Mechanics at the Ångström Laboratory. His research interests focus on processing-microstructure-property relations of polymer and composite materials. He lectures in solid and structural mechanics on undergraduate and graduate levels.

Generally, a mixed experimental-modelling approach is advocated and geared towards rationalised design of new materials, with regard to engineering performance, extended lifetime and sustainability. The laboratory facilities feature high-resolution X-ray computed tomography, instrumented ultramicrotomy, mechanical testing with digital-speckle photography from sub-N to kN loads, scanning-electron microscopy with in-situ mechanical testing, and fast computers for finite element modelling and 3D image analysis. In particular, recent research is focussed on the physics and mechanics of nanoscale cutting of polymers. An ultramicrotome has been instrumented to measured cutting forces for chips with nanoscale thickness. In combination with atomic force microscopy and finite element simulations based on physical mechanisms, the goal is to provide understanding which can be used to optimise cutting and machining conditions on small scales.
