The Scientific Technical Committee on Precision Engineering and Metrology (STC P) held two meetings in 2024—on February 22 and August 23. The February meeting took place in Paris, with 66 members and 14 invited guests in attendance. The August meeting was held in Thessaloniki, Greece, and was attended by 57 members and 25 invited guests.
During the February 2024 meeting, STC P reviewed the status of upcoming keynote papers, which had been determined in previous meetings and align with current manufacturing trends influencing STC P’s activities. Profs. Archenti, Gao, and Lanza provided status updates on the 2024, 2025, and 2026 keynotes, respectively.
Introduced by Prof. Morse, Dr. Marc Wawerla from Zeiss Industrial Quality Solutions delivered an in-depth presentation titled "Metrology and Precision Engineering for Decarbonization." Highlighting how precision engineering can support decarbonization efforts across industries. In the discussion, Dr. Wawerla addressed questions regarding the net impact of decarbonization, the role of AI in Zeiss's processes and products, and the company's involvement in EV battery metrology at both the cell and pack levels. He also emphasized the importance of customer experience in the transition to decarbonized technologies, using Tesla's success as an example of balancing performance and sustainability.
Benjamin Montavon presented the new CIRP publication series, CIRP Novel Topics in Production Engineering (CNPTE), on behalf of STC-P terminology committee member Prof. R. Schmidt. He welcomed proposed topics from STC P members. At the start of the presentation, he highlighted the current CIRP dictionaries as a motivating example for establishing a structured method to introduce new ideas.
There were six short technical presentations followed by short discussions:
1. A vision for virtual CT based on supervised learning (Florian Stamer)
2. Experimental study of the measurement of ambient thermal effects in large machine tools with an integrated multilateration approach (Unai Mutilba)
3. Traceable Identification of Geometric Accuracy on Rotary Axes – Development of Novel Contactless Material Standard (Fabien Viprey)
4. Spindle performance measurements via laser-embedded tool and metrology suite (Gregory Vogl)
5. Toward Industry-Oriented Quantum Imaging with Quantum Ghost Imaging (Elie Magnon)
6. Deep Learning-Enabled Virtual Process Sensing for Enhanced Quality Prediction in Resistantce Spot Welding (Peng Wang)
Information on relevant ISO/TC213 and ISO/TC39 standards were provided by Dr. A. Balsamo and Dr. A. Donmez, respectively. These were followed by the updates from CWG meetings and update on terminology committee activities Novel Topics in Production Engineering.
During the August 2024 meeting, STC P expressed gratitude to Prof. A. Archenti and his co-authors for preparing and presenting the 2024 STC P Keynote paper, titled “Integrated Metrology for Advanced Manufacturing.” Prof. Archenti presented the paper during the opening session on August 19th in Thessaloniki, where it garnered significant interest from CIRP members. STC P also reviewed the progress of future keynote papers and provided feedback to the respective authors.
STC P discussed the status of the upcoming keynote papers, which were determined during previous meetings, reflecting the general trends in manufacturing that influence the STC P’s scope of activities. An in-depth discussion on future keynotes and CIRP Novel Topics on Production Engineering (CNTPE) was initiated and deliberated among the authors. The keynote topic for 2027 was voted on, with 'Optical Measurements in Machines' selected as the theme and two topics for CNTPE was voted on, with ‘State-of-the-Art in Optical Gear Metrology’ and ‘Large Machine Tool Calibration: Shifting towards fast, integrated, cost-attractive and low complexity solutions’.
The following short technical presentations were given during the meeting, followed by short discussions:
7. Diamond-machined nanometric surficial wavelength-selective reflectors enable structural coloration of wide gamut and local angle independence (Ping Guo)
8. Active stereo-photogrammetry measurement system using single-frequency fringe projection for measuring metal additive manufacturing parts (Benny C.F. Cheung)
9. Development of new device for direct calibration of force-induced displacement errors of Instrumented Indentation Test machines (Giacomo Maculotti)
10. Robust digitalization by process monitoring improvement in Industry: A case of an emulsion system in a machining line (Mariano Coll)
11. Estimation of measurement uncertainty based on design of experiments and derivation of a generalized linear model (Guido Tosello)
12. 6D object pose estimation in the age of Foundation Models (Benjamin Montavon)
13. Comb-rooted generation of terahertz frequencies (Seung-Woo Kim)
14. Indirect fluorescence-based geometry measurement (Dirk Stöbener)
STC P paper session was held on Monday and Tuesday, August 18-19, 2024. There were 10 technical presentations covering various research topics, The papers cover a broad spectrum of advancements in measurement and manufacturing technologies. Topics include the impact of rotary axis angular errors on robotic probing, estimation of kinematic errors over wide indexing ranges, and predictive digital twins for dynamic error control in ultraprecision diamond turning. Other studies explore deep learning reconstruction for X-ray CT, ISO GPS verification, quality characteristics in generative AI models, residual stress evaluation in polymers using THz polarization, a new interferometric measurement method (P-8), surface asymmetry measurements via cyclic azimuthal shearing interferometry (P-9), and in-situ fluid thickness measurements using fluorescence. They were all well presented by the authors and generated lively discussions during the session.
