In 2025, the Scientific Technical Committee Cutting STC “C” continued its work on processes and techniques used to shape components by material removal under the leadership of the current officers:
Chair: S. Melkote, Vice Chair: P.-J. Arrazola, Secretary: V. Schulze
The group held one meeting on February 20, 2025, in Paris and another meeting on August 22, 2025, during the GA in Stockholm, Sweden.
The cooperative working group coordinated by I.S. Jawahir on Integrated Machining Performance for Assessment of Cutting Tools (IMPACT) launched in 2021, presented its progress and finalized its work with the presentation of the related keynote “Revisiting machinability assessment: Towards total machining performance” published in CIRP annals vol. 2 2025. This WG provided understanding, and its outcome published by the team as review papers in CIRP JMST assists researchers and industry practitioners in the following specific topics
• A: (D. Axinte and Z. Liao). Survey of current best practices in machinability evaluation and industrial knowledge for maximizing machining performance
• B. (H. Attia and A. Sadek). Physics-based model development and fundamental characterization of cutting tool performance
• C. (P. Mativenga and J. Schoop). Engineered design of cutting tool material, geometry, and coating for optimal performance and customized applications
• D. (A. Shokrani and T. Schmitz). Design and development of smart tooling/sensors for closed-loop
• adaptive machining.
• E. (M. Dix and H. Ghadbeigi). AI-based multi-objective optimization of total machining performance, including tool-wear, chip-form, surface integrity, cutting forces, dynamic stability, part accuracy, etc.
The cooperative working group on Sensor Integrated Manufacturing proposed by F. Bleicher, which was already approved in the GA meeting in 2024, detailed its plans and prepared the outline of the work, including the distribution of a standardized tool holder, a detailed round robin with a standard programme, and a data space allowing for AI-based analysis of the data generated. The presentation of F. Bleicher within the GA meeting was found to be of enormous interest by the members of STC “C” and various other STCs.
In all meetings, a discussion on further cooperative work took place. The Cross-STC Collaborative Working Group proposed by Th. Bergs “ManuTech X”, which was approved in the GA meeting, will be strongly supported by STC “C” with relevant use cases and the establishment of relations to potential industrial applications.
In addition, technical topics and proposals for keynotes were presented and discussed in the two STC “C” meetings. These presentations are listed below.
