We are glad to invite you to the 19^th CIRP Conference on Modeling of Machining Operations, which will be held from 31^st May – 02^nd June 2023 in Karlsruhe, Germany. The conference is a great chance for experts from academia and industry in the field of modeling of machining operations to present and discuss their findings on a very high level, which stimulates and supports the knowledge in this field.

The 19^th CIRP Conference on Modeling of Machining Operations continues a long series of conferences, which was founded by our esteemed colleague Prof. I.S. Jawahir. In the previous conferences high quality research findings in the area of Numerical and Analytical Modeling of Machining and Surface Integrity and Tribological Aspects of Cutting were presented. Topics like Multiscale Modeling, Artificial Intelligence, Fluid Dynamics and Surface Conditioning in Machining Processes are becoming more important. Therefore, these topics are included in the 19^th CIRP Conference on Modeling of Machining Operations and will be discussed in separated sessions, which is a chance for the researchers to discuss their findings in detail. The success of the conference is guaranteed by the international scientific committee including the greatest researchers of this field.
