Round Table: Additive Manufacturing - Trends, strategies & visions
There is hardly any manufacturing process that has shaken up the existing technology landscape in recent years as much as additive manufacturing. Production of complex single parts with many freeform surfaces, customized applications or individually designed components are just some of the advantages attributed to additive processes. Manufacturing companies speak of increased agility and flexibility even in the production of small quantities. Questions remain: What else needs to be done in additive manufacturing? What are current research activities? What potential for optimization still exists compared to subtractive processes? And what can metrology achieve here? These and other questions will be discussed in the 1st Bruker Alicona Round Table with experts from research and industry. Our experts are Robin Day from the Fraunhofer Institute for Production Technology (Germany), James Hunt from the Advanced Manufacturing Research Center (AMRC, UK) and Henry Greenhalgh from the international manufacturer HiETA Technologies (UK), specialized in the use of Additive Manufacturing (metal 3D printing), particularly in the areas of thermal management and light-weighting.

New measurement methods make new manufacturing technologies measurable
Development and optimization of new technologies for production of components with tolerances in the single-digit µm range is one of the core activities of MIFHySTO, a facility at FEMTO-ST research institute in Besançon, France. Michael Fontaine´s research deals, amongst other projects, with the question on how to increase machining accuracy of micromachining machines. Industrial partners are often very good at producing parts but are facing challenges in terms of controlling them. In this interview with Anne Calvez from the French Bruker Alicona team, Michael will present how optical metrology can particularly help to optimize micro EDM, turning and milling manufacturing processes through 3D metrology learnings on machined surfaces and tools. Applications presented include wear analysis, GD&T measurements and surface roughness measurement of tools and micro precision parts. In addition, new fields of use such as measurement of nano textures on steel, carbide or coating is presented. Also under discussion is why established measurement methods available in his lab are no longer sufficient for some applications and what new technologies are needed to make new production technology possibilities measurable.

Smoothing, polishing, rounding, deburring – how metrology increases efficiency
Some things do not change, even with continuous technology advances. In the past and today, machine tool manufacturers must produce components with perfect surface quality and ensure the process reliability of their production strategy. Innovative technologies have always made a decisive contribution to competitive advantage. Soran Jota from OTEC Präzisionsfinish management has been using Bruker Alicona's Focus Variation for a decade. He reports first-hand how the reliability of his processing machines as well as the quality of drill components, milling cutters and gear parts could be optimized using this measurement technology. With the launch of a new mass finishing machine, OTEC is currently preparing the next step in its quality assurance strategy by measuring in the machine. Soran Jota talks to Bruker Alicona Sales Manager Urban Muraus about how this is intended to work in production.

Artificial intelligence creates new possibilities
Artificial intelligence has already found its way into many areas of our everyday life. Common devices such as our smart phones have capabilities that were only dreamed of a few years ago. Machines learn from experience and as a result can solve the most complex problems. This is primarily made possible by new types of algorithms, improved computing power and a large amount of collected data. These decisive developments also expand the spectrum of possibilities for manufacturers of measuring equipment. At Bruker Alicona, we use AI in algorithms for measuring high-resolution 3D optical data, and for automatic evaluation of this same 3D dataset. In this session, Thomas Lankmair, Head of Application Competence Center (ACC) at Bruker Alicona, will show which measurement jobs can be solved based on AI. He will present applications that would have been difficult or impossible to solve using conventional methods. These also include an AI-based solution for automatic defect detection and measurement. We will also show you how you will be able to soon integrate AI into your measurement technology independently.

Towards uncertainty evaluation with optical coordinate metrology
Coordinate metrology is mainly applied to ensure production quality. Prof. Richard Leach introduces the different types of coordinate metrology and how they differentiate. In particular, the difference between traditional tactile (contact) technologies and new optical methods are discussed in detail. One of the key aspects in terms of verifying measurement accuracy is the use of standards and how measurement uncertainty comes into play. Here, Richard Leach will focus on how this is handled in relation to optical coordinate metrology. Also, an outlook on further developments in the field of calibration for coordinate measurement technology is given.

Optimization of manufacturing processes through optical measurement technology
Machines networking is one of the major topics at the Institute for Machine Tools at the University of Stuttgart (Germany). Research is dedicated to machines networking and technologies to implement self-optimizing production manufacturing strategy. One focus of its research activities is process control of e.g., additive-subtractive process chains with automated measurement technology. An example where this is successfully applied is wear analysis. Prof. Christian Möhring describes which methods are used in milling technology to understand, for example, wear mechanisms as well as the correlation between the workpiece surface machining and surface condition. This discussion with Bruker Alicona Managing Director Christian Janko also focuses on the role of metrology in various manufacturing processes. It addresses particularly the production of functionally relevant surface structures, a clear trend that will increase the importance of sensor technology in metrology.

EDM or laser? How to achieve the highest possible precision and efficiency in manufacturing
It is a controversial debate in industry: Are laser processes increasingly replacing EDM (Electrical Discharge Machining) technologies? Mark Raleigh from EDM Intelligent Solutions shares this opinion only to a limited extent. He still sees applications where EDM is the better technology and combines the strengths of the tried and tested with the advantages of the new technique. Consequently, he increases both efficiency and product quality in production by applying highest possible machining precision and machining speed. In this interview with Bruker Alicona General Manager Christian Janko he highlights the differences and similarities between the two processes and explains the metrological challenges he sees in the quality assurance of relevant component characteristics.

Higher efficiency, better product quality & function prediction in micro gearing
Key functions of complex products can often only be realised by using high-precision components. The production of micro-components close to the technological limits, which often have tolerances of only a few μm, represents a major challenge for manufacturing. The wbk Institute of Production Science at KIT is researching approaches of function-oriented quality assurance of micro gears. The vision is to implement intelligent quality control loops by integrating in-line measurement technology into production systems, which will improve product quality as well as increase efficiency in production. The combination of measurement data with artificial intelligence is intended to optimise not only the quality of the manufactured gears, but also the functional behaviour of the end product. Based on the functional predictions, strategies for adaptive manufacturing and intelligent assembly of micro-gears are to be developed. The optical micro-coordinate measuring machine µCMM is used for in-line metrological acquisition during micro-gear production

What makes for efficient production in tool making?
The demands on plug connections are high. Reduced size and low power consumption combined with higher performance in even harsh environments are typical quality requirements for these electronic components. Highest precision, verified by using modern measurement technology, is therefore one of the top premises that TE Connectivity practices during the entire manufacturing process. Uwe Soldner, Toolshop Manager EMEA and Steffen Schoellhammer, Toolshop Manager at the facility in Wört/Germany, talk to us about efficient production and how measurement technology can contribute to this efficiency. One aspect is that a measurement process is used in several phases of production, from tool development to quality inspection of the end product. Also a topic of discussion in this round: What are the strengths and weaknesses of a CT compared to an optical CMM?

Evaluating press-fit zones metrologically
Alle Einpresszonen, die am Markt verfügbar sind, weisen eine Gemeinsamkeit auf: Die Geometrie ist ein entscheidender Faktor für eine sichere, stabile, gasdichte und gut leitende Verbindung. Messtechnisch heißt das, es müssen komplexe geometrische Merkmale wie Kantenradien, Hüllkreise an bestimmten Positionen oder Übergänge wie der von der Einpresszone zur Einpresszonenspitze geprüft werden. Frank Uibel, langjähriger Experte und Unternehmensberater in der Einpress- und Stanztechnik, unterhält sich mit Bruker Alicona Vertriebsleiter Urban Muraus darüber, worauf es bei einem Messsystem ankommt und spricht vor allem über Anforderungen an Präzision, Messgeschwindigkeit und Benutzerfreundlichkeit.

How metrology can enable physics-based analysis of material behavior
With Trent Woodcock, Applications Engineer at Third Wave Systems (TWS)/US, we are happy to uncover the role of metrology in machining analysis. TWS is one of the premier Computer Aided Engineering (CAE) provider for companies that machine. Their technology helps to dramatically reduce the cost of machined components, accelerate design cycles, improve part quality, and get to market faster. The Bruker Alicona system is situated in their Testing and Validation Center to perform accurate and repeatable measurements of inserts and solid end mills. Advanced metrology has enabled TWS to further understand material behavior in high stress/strain cutting scenarios. Their detailed analysis of temperature, stress, and chip flow enable users to identifying optimal process conditions and understand the impact on tools and machined surfaces. In an interview with Faran Misaghi, a member of the Bruker Alicona US team, Trent will discuss a use case in the Aerospace and Defense industry. A study that significantly reduced the process of selecting the cutting tool best suited for high efficiency machining of titanium.
