In 2022, 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: D. Biermann, Vice Chair: S. Melkote, Secretary: P.-J. Arrazola

The group held one virtual meeting on 2022 February 17th, due to the COVID-19 pandemic and another face-to-face meeting in 2022 August 26th during the GA in Bilbao, Spain.

The cooperative working group on Integrated Machining Performance for Assessment of Cutting Tools (IMPACT) launched in 2021 presented its progress. The WG on gear cutting decided to finish their activity due to the COVID-19 pandemic.

This WG will provide understanding and will assist 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
• (H. Attia and A. Sadek). Physics-based model development and fundamental characterization of cutting tool performance
• (P. Mativenga and J. Schoop). Engineered design of cutting tool material, geometry, and coating for optimal performance and customized applications
• (A. Shokrani and T. Schmitz). Design and development of smart tooling/sensors for closed-loop
• adaptive machining.
• (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.

In addition, technical topics and proposals for keynotes were presented and discussed in the two STC “C” meetings. These presentations are listed below.

I- Virtual STC “C” meeting, February 2022

At the virtual meeting – attended by 90 members, 15 research affiliates, and 6 guests, the following presentations on cooperative work and potential keynotes ware made. Due to time restrictions in the virtual meeting, there were no technical presentations.
