​The 20th edition of the CIRP Conference on Modeling of Machining Operations (CIRP CMMO 2025) was held in the beautiful historical city of Mons, Belgium, on 22nd and 23rd May 2025 (welcoming event on 21st May in the evening).​ ​Founded in 1998 by Prof. I.S. Jawahir, this high-level conference will be an excellent opportunity for experts in the field of modeling of machining operations, coming from both industry and academia, to share knowledge, discuss and present their latest developments and findings.​

​The conference brought together 190 attendants who enjoyed the presentation of 121 articles on the modeling of manufacturing processes, and especially machining operations, accross 31 sessions. A welcoming event, 'Early Registration & Get Together', took place on 21st May in the evening at the historical building 'Houdain' of the Faculty of Engineering of UMONS. The gala dinner of 22nd May evening was hosted at Van der Valk Hotel Mons Congrès & Spa. The attendants had also the chance to listen to the keynote presentations of Dr. Pedro-Jose Arrazola (Mondragon Unibertsitatea, Spain) and Ir. Tom Jacobs (Sirris, Belgium).

​The accepted articles have been published in open access by Elsevier in the Procedia CIRP journal after a reviewing process by the international Scientific Committee including the leading researchers of the field.​ The articles are available here.

​It was a real pleasure to welcome you in Mons!​

Pedro Arrazola

Future trends in machining: the role of modelling

​Dr. Pedro-José Arrazola Arriola is a senior lecturer in mechanical engineering and Head of the Machining Research Group at Mondragon Unibertsitatea (Spain). With 25 years of experience in metal machining, his work focuses on the study, understanding, and optimisation of machining operations through experimental and numerical approaches. His expertise includes fundamentals of cutting, modelling of machining processes, surface integrity, process monitoring, the environmental impact of machining, and the finishing of additive manufacturing components. Dr. Arrazola has an H index of 32 (WoS) and has published over 375 articles and three book chapters. He has led major research projects such as FATECO (H2020-RFCS) and MACH40 (EITM). He has also participated in more than 102 scientific and industrial projects (EU, National, and regional) across multiple sectors, including automotive, aeronautical, railways, and medical. As a “Fellow Member” of CIRP, the International Academy for Production Engineering, Dr. Arrazola served as secretary of the Scientific Technical Committee for Cutting (STC-C) from 2018 to 2022 and currently holds the position of vice-chairman.

Tom Jacobs

How industry and academy worked together to tackle the tool wear challenge

Tom Jacobs graduated at the University of Leuven in 2004 as a Mechanical Engineer, specialized in Production Management and Technologies. After a Master in Policy Economics in 2005, he started his carreer at Sirris (formerly known as WTCM). As a project engineer he explored together with a collective of innovation companies novel machining technologies (e.g. micro milling, ultrasonic assisted machining and cryogenic assisted machining). He distributed his knowledge through over 100 (mainly Belgian) machining companies by guiding them on innovation trajectories and introduction projects.

The last decade, as a senior expert at Sirris, he followed up the trend towards digitization and the introduction and use of sensor data into the prediction of the outcome of machining processes. By integrating the knowledge available at other experts within Sirris, other (Belgian and European) academic partners and the industrial companies, he set up applications and research projects with SME’s and large companies.
