Thermal effects are regarded as a major contributor to errors on precision equipment, instruments and systems within precision engineering.

Measurement is becoming even more important as workpiece tolerances decrease, as thermal effects not only use a larger part of the tolerances, but also influences repeatability, long term stability and general issues such as “lifetime” and “process-quality” of machine tools and measuring equipment.  In the work-place of today, these play an important role in high-throughput production equipment and many scientific instruments e.g. operating at cryo-genic and Ultra-high vacuum.

We were delighted to bring together leading expertise globally to an open forum for focused presentations and discussions on thermal issues. This includes manufacturing, temperature control in electric mobility (windmills), cryogenic vacuum and scientific instrumentation within large science projects.

We are seeking papers in the following categories:

1. Measurement of thermal influences in production equipment, process and product

  • Understanding the machines thermal behaviour and the errors on the machined workpiece follows a deep understanding and evaluation of the thermal chain of causes and the error sources
  • Equipment and methods for direct and indirect measurements

2. Modelling and model reduction techniques

  • Modelling of temperature and deformation fields: lumped-mass, structural FE, CFD
  • Reduction of  multi-physics models, reducing complexity and size
  • Thermal mode shapes (temperature and deformation): Eigen-modes, POD-modes, FRF-based modes

3. Compensation and correction of thermal effects  (e.g. Artificial Intelligent algorithms and techniques) 

  • Reducing thermal errors of machines based on control theory
  • Input data and sensor data processing, modelling techniques and actuator control
  • Implementation in machine controls and manufacturing planning

4. Design principles for thermally robust production equipment (e.g. Machine Elements, Machine Structures)

  • The enhancement of machine positioning based on high precision machine design principles. These aim to reduce either the generation of temperature gradients or the deformation sensitivity of the machine structure to them. (Characteristic examples of current research: Heat pipes, Phase-change materials, cooling systems, heat accumulators)

5. Test workpieces and assessment 

  • Methods for evaluating thermal errors of machines by manufactured testworkpieces, design of testworkpieces, manufacturing strategies and evaluation approaches

6. Thermo-energetic design

  • Design, correction or compensation measures that satisfy the conflicting goals of reducing energy consumption and increasing accuracy and productivity in machining

7. Temperature measurement & control 

  • Accurate and fast temperature measurement in scientific and industrial environment
  • Control algorithms, thermal actuation
  • Thermal system identical measurements (model measurements)
  • Challenges under cryogenic conditions

Next Phase in ASML’s Digital Engineering: Modular-Swift-Precision Modelling 

ASML designs and manufactures one of the most technologically advanced and complex machines humans have ever built. Developing such machinery needs an extreme collaboration between different clusters and disciplines. Parallel to this complexity, ASML’s ambitions towards 2030 are high with faster development, integration and learning cycles. Customers are in need of better lithography and metrology machines in time that are reliable to keep up with world’s hunger for more advanced chips on all fronts. This puts an extremely important role on ASML engineering to be more robust, connected and efficient within its product development cycle.

Digital Modelling has already been the engineering tooling since long years at ASML however when it is not interconnected, modular and fast it is only solving part of engineering problems at a limited scale and speed. In an era where time is as valuable as accuracy, Modular Swift-Precision Modelling emerges as a digital modelling approach, blending rapid computational speed with high-precision modelling. The keynote speech at the euspen Thermal Issues Group Meeting will introduce and explore the transformative capabilities of modelling in ASML’s engineering domain.

Modular Swift-Precision Modelling represents a shift in engineering modelling. It integrates the comprehensive detail of high-fidelity engineering simulations with the agility of fast-system modelling, enabling engineers to achieve accurate results at speeds previously unimaginable. This talk will unveil the intricacies of the approach, emphasizing its potential to significantly shorten design cycles while enhancing the accuracy of predictions and analyses at higher level system scale.

Practical applications across some ASML use cases, specifically within thermal domain, including design, integration, validation and machine control will be highlighted. These case studies will demonstrate this method’s claim for effectiveness in optimizing processes, improving system performances, and driving innovation at ASML.

The keynote will also delve into ecosystem of Modular Swift-Precision Modelling. We will discuss the evolving landscape, the ongoing advancements in computational technology, digital processes to keep up with the exploding variants and datasets and the skill sets necessary to leverage the approach effectively. The speech aims to inspire engineers, industry leaders and academic partners to embrace similar novel approaches in digital modelling.
