Virtual Lamdamap 14th International Conference & Exhibition
10th -11th March 2021
10th – 11th March 2021
Virtual Conference & Exhibition
euspen’s 14th International Conference and Exhibition on Laser Metrology, Coordinate Measuring Machine and Machine Tool Performance, (LAMDAMAP 2021) was planned to be held at KTH Royal Institute of Technology, Södertälje Campus, Södertälje, Sweden. In light of the COVID-19 pandemic, it has been decided to deliver this meeting as a “virtual online web-meeting”, to ensure the participants remain safely connected.
The 14th International Conference and Exhibition on Laser Metrology, Coordinate Measuring Machine and Machine Tool Performance, (LAMDAMAP 2021) will be organised by euspen drawing together many of the worlds distinguished scientists drawn from all areas of science, engineering and medicine. It embraces NEW TOPICS and a NEW FORMAT.
Advanced machine tool metrology supports superior part production; enabling, understanding and tracking of baseline performance machines. Whilst the trend towards nanometre level surfaces finishes and features progresses, matching both form and finish coherently in complex parts remains a major challenge.
This conference will take place in virtually and will focus on Metrology in New Fabrication Techniques; New Developments in Measurement Techniques; Novel Manufacturing Technologies & Machine Tools; Performance Evaluation for Machine Tools & CMMs; Roughness & Machine Tool Standards; Accuracy and Performance Evaluation of Industrial Manipulators; Integrated Metrology in New Fabrication Techniques and Machine Learning for Metrology and Precision.
The organising committee for euspen‘s 14th Lamdamap Conference and Exhibition is Prof. Andreas Archenti, KTH Royal Institute of Technology, SE; Prof. Liam Blunt, University of Huddersfield, UK; Prof. Andrew Longstaff, University of Huddersfield, UK and Prof. BG Rosén, Halmstad University, SE.
We understanding networking is the key to the success of euspen’s events, and whilst we have had to adapt this event and bring this to you virtually, we still hope the structure will allow our presenters and registrants to discuss issues of immediate relevance to the area of machine tool metrology. To stimulate such cross fertilisation of ideas and experiences, we have incorporated an extended coffee break at the end of each oral session to allow for an interactive discussion with presenters and all registrants alike.
The production of more and more accurate and smaller and smaller components relies and indeed is underpinned by advanced machine tool metrology, which facilitates the assessment of performance of machines. This requirement becomes more pressing as the drive in industry towards the greater use of nano-scale surface finishes and features gathers pace. It is vital that form and finish is produced consistently in small complex parts, and it is here that the key challenge for advanced metrology solutions exists today.
The extended coffee breaks allocated for discussing presentations, will allow for the transfer of knowledge bringing the next generation of manufacturers to incorporate available advances in measurement techniques to meet tomorrow’s specifications.

Metrology enabled robotic machining
Serial-link industrial robots are relatively inexpensive systems that have large working volumes. They are used for many manipulative tasks, particularly those that are repetitive and do not depend on fine precision. Limitations arise from revolute joint backlash, friction and low stiffness, which induce nonlinear dynamic effects. Control using internal encoders is not generally effective for precision robotic machining, both for absolute positioning and relative surface finish. The robot control is generally of low bandwidth (< 10 Hz) and not able to compensate for higher bandwidth dynamics induced by machining processes. It is possible to compensate for positioning errors by introducing external metrology, for example, using a laser tracker to monitor a tool path and providing additional feedback to the robot controller. Higher frequency compensation of machining processes requires additional actuation that is mobile with the robot motions. External inertial actuators close to the machine tool may be used to apply compensating dynamic forces. Laser tracker feedback of displacement signals may be adequate if vibration levels are within resolution, otherwise displacement roll-off with frequency may be covered by accelerometer signal feedback. The keynote will also address control strategies that are effective for such external metrology in reducing machining errors.
Patrick Keogh is a Professor in Machine Systems in the Department of Mechanical Engineering at the University of Bath, UK. He obtained undergraduate and PhD degrees from the universities of Nottingham and Manchester, respectively.

Correction of thermo-elastic errors in machine tools – How digital twins help to minimize TCP deviations
A central goal of machine tool development is to improve manufacturing productivity and accuracy. Increasing the productivity usually causes larger heat input into machine structures, which deforms them thermo-elastically, and subsequently, reduces machining accuracy. The speech discusses a digital-twin based correction method, which uses a computer model to calculate the thermo-elastic errors at the Tool Center Point (TCP) based on current data from the control system and ambient temperature sensors. Finite element machine models describe the machine structure, the structural variability due to traverse movements of the feed axes, and physical relationships. Model-order-reduction methods enable process-parallel computation of high-resolution models in thermal real-time. The machine models need constant updating; new methods allow identifying larger structural models by condensing parameters to a minimum. Volumetric correction in the control system reverses numerically predicted thermo-elastic errors at TCP in the workspace. Photogrammetric measurement systems verify the correction results. The talk concludes with the implementation of all measures in a conceptual machine tool at Technische Universität Dresden.

Wayland Additive, UK
Additive manufacturing with electrons
Electron beam additive manufacturing was introduced as a process over 20 years ago, along with its competing technology selective laser melting. Both have advanced and developed in that time. These two technologies offer the user something different. Wayland is a new entrant to the metal additive market, offering a 3rd way, with a new technology “NeuBeam” that has electron beam melting at its core. Wayland have started a fresh and developed the technology from the ground up. This paper looks at electron beam AM / NeuBeam from a machine builder’s perspective as well as the users’ perspective, sharing the fundamental aspects of the technology to the realisation of a manufacturing process. The inherent advantages of the technology are mapped through to end use benefits, such as productivity, controllability, flexibility and quality assurance. Electron beam AM is one of the tools in the additive manufacturing tool set, but one that is less well known. Development of NeuBeam by Wayland Additive will be presented and its implications for the user will be discussed.

Machine performance evaluation for metal additive manufacturing
A qualified additive manufacturing (AM) part will only come from a qualified AM machine, and machine qualification requires machine performance evaluation. Although additive manufacturing is a relatively new process and machines are continually changing, the test methods used in their performance evaluation can leverage expertise developed in other areas, especially machine tool metrology. Performance evaluation can take several approaches, from building and measuring a test artifact, to evaluating individual machine components, to a combination or hybrid approach. Best practices specific to additive manufacturing machines are currently under development and evaluation, but much is already known. This presentation will discuss ongoing work on this topic at the National Institute of Standards and Technology, with a particular focus on laser powder bed fusion AM machines.

Dimensional measurement traceability by X-ray computed tomography – where are we?
Long synonymous with medical imaging, X-ray computed tomography (CT) is proving its worth in industrial applications such as material characterization, defect analysis, and dimensional inspection, e.g., of additively manufactured components. Since 2005, when the first purpose-built industrial X-ray CT instrument was made commercially available, there have been significant efforts to understand just how reliable dimensional measurements by X-ray CT are. In metrology, the ultimate measure of confidence is metrological traceability—a clearly-defined but often not well-understood property of a measurement result. Metrological traceability places measurements on a comparable scale and provides a quantitative indication of measurement quality in the form of an uncertainty statement. In this keynote presentation, we provide a high-level discussion about traceability of X-ray CT dimensional measurements to the SI unit of length, review relevant work in empirical determination of X-ray CT measurement uncertainty, and propose a framework for model-based uncertainty assessment and instrument scale calibration as a unified approach to traceability.
A recent (2018) graduate of the Katholieke Universiteit Leuven, Massimiliano Ferrucci has over 11 years of research experience in dimensional metrology, spanning several measurement technologies from gauge block comparators to optical coordinate measuring systems and X-ray computed tomography (CT).

Cranfield Precision, Division of Fives Landis Ltd, UK
Recent developments in freeform grinding for large EUV lithography optics and head-up display mirrors using a bespoke tool path generation package, MöbiusCAM
Fives, through its R&D centre, Cranfield Precision, Division of Fives Landis Ltd, has recently developed two machines currently being deployed in the manufacture of high precision optics.
A large grinding machine capable of grinding off-axis optics up to 1.6 m (OGM1600) has recently commenced production grinding of large mirrors for extreme ultraviolet (EUV) semiconductor wafer lithography systems. A novel machine concept known as the Twin Turret Grinder (TTG) is being used to develop new manufacturing methods for head-up display mirror molds. Both machines use our custom tool path generation software, MöbiusCAM.
MöbiusCAM uses a step-by-step wizard interface to facilitate the programming of both machines for the grinding and in-situ measurement of complex geometries. The software can also be used to import, analyse and manipulate measurement data from third party, off machine metrology systems. The software is highly flexible and can be made compatible with any machine configuration.
Typical data inputs include, machine axes configuration, including axis limits, tooling available for machining, the surface to be processed and operations to be performed, e.g. freeform spiral, raster, edging etc. Tool paths can be modified to compensate for measured surface errors and rapidly converge on the required form accuracy. For the given required surface geometry and machine, inverse kinematics calculations produce the appropriate machine motions. Conversely, machine axes position data logs (produced during grinding and including logged error motions) can be used to compute the tool position during grinding in order to predict the actual profile ground during machining cycle.
The presentation will include an overview of MöbiusCAM and some recent results from OGM and TTG machines.
