Lamdamap 2017 Keynotes

Prof Xiangqian (Jane) JIANG, University of Huddersfield will present:

Surface metrology for future manufacturing


This talk is about the essential foundations of surface metrology for the future manufacturing. Manufacturing is going through a ‘disruptive revolution’, from traditional, through innovation to future breakthrough factories that are fully intelligent and digitalised, allowing autonomous manufacturing during 2025-2050. This demands the creation of new technologies and methodologies to make surface design, production and quality control of complex products intelligently and automatically and thereby suitable for future production.


The talk will discuss the underpinning infrastructure of surface manufacturing, with an emphasis on shifts in developed technologies that have/will have a major effect on improvements in its manufacturing capability. These include fundamentals for imaginative product design, metrology, embedded sensors/instrumentation, data analytics, and breakthroughs in-process quality control.

Dr Josef MAYR, IWF, ETH Zurich will present:

Thermal error compensation of machine tools


Thermal errors of machine tools are one of the major error source causing geometrical deviations on the machined workpieces. There is an increased demand for complex precise workpieces manufactured on 5-axis machine tools with a high thermal stability, especially in aerospace and medical engineering applications.

In the presentation the aspects of model based thermal error compensation using the machine tool feed axes for error correction will be addressed. Two recently developed thermal error reduction techniques especially designed for 5-axis machine tools will be presented. One machine tool is compensated using a linear model, the other machine tool uses a dynamic model consisting of a system of differential equations. In both machine tools a touch probe system exchanged into the tool holder is used to measure all relevant thermal position and orientation errors of the machine tool spindle in one hand and in the other hand of the rotary/swivelling axis unit of the machine tool. The possibility of using a touch probe system for thermal machine tool error measurement is investigated and will be addressed.

The on-machine measurements are used for adjusting the compensation models used to guarantee long term stability of thermal error compensation. The presentation will close with a detailed validation of both approaches and their application into machine tools control for automatic thermal error compensation of 5-axis machine tools.



Josef started his technical career with an apprenticeship for mechanics at KUKA Schweissanlagen und Roboter GmbH in Augsburg, Germany, a company well known for their industrial robots. After finishing his apprenticeship he went to high school and got a degree in mechanical engineering at the Technical University of Munich in 2004. In 2004, he started his research at ETH Zurich and got his PhD in 2010 continued by two years working as a Postdoc. The main focus of this research was on thermal behaviour of machine tools. His PhD-Thesis was awarded by the Fritz Studer Award 2012.

After one and a half year working for MCI, Management Center Innsbruck in Austria, in 2013 Josef joined the inspire AG in Zurich, a transfer institute close connected to ETH. He is there responsible for a group working on the topic of thermal errors of machine tools.

Josef has authored over 30 publications and is lecturing and teaching in manufacturing technologies at the ETH Zürich and the Interstate University of Applied Science in Buchs, Switzerland.
