The development is supported by creating a CFD simulation predicting the characteristics of the coolant flow during the drilling process. In this context, a validation of this simulation is required to build the foundation of including subsequently the influence of chip formation and the related temperature development into the numerical model. The present paper introduces the initial design of the fluid flow model and the required experimental validation achieved by high-speed recordings of the visualized cooling lubricant flushing the region of interest between tool and workpiece. The application of Particle Tracking Velocimetry to the evaluation of the numerical model to identify potential deviations between the coolant flow of the experimental drilling process and the simulated flow field is presented.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Keywords<\/strong>: Drilling, Inconel 718, Difficult-to-cut materials, CFD simulation, FEM-FBM Coolant, High-speed analysis<\/p>\n\n\n\n<div style=\"height:20px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Video presentation<\/strong><\/p>\n\n\n\n<figure class=\"wp-block-video\"><video height=\"1080\" style=\"aspect-ratio: 1920 \/ 1080;\" width=\"1920\" controls src=\"https:\/\/cirpicme.org\/wp-content\/uploads\/2022\/06\/Tobias_Wolf.mp4\"><\/video><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Presenting author<\/strong><\/p>\n\n\n\n<figure class=\"wp-block-table is-style-stripes\"><table class=\"has-background\" style=\"background-color:#f3f4f5\"><tbody><tr><td><\/td><td><\/td><td><\/td><\/tr><tr><td><img data-recalc-dims=\"1\" loading=\"lazy\" decoding=\"async\" width=\"150\" height=\"115\" class=\"wp-image-3691\" style=\"width: 150px;\" src=\"https:\/\/i0.wp.com\/cirpicme.org\/wp-content\/uploads\/2022\/07\/Tobias_Wolf_Photo.jpg?resize=150%2C115&#038;ssl=1\" alt=\"\" srcset=\"https:\/\/i0.wp.com\/cirpicme.org\/wp-content\/uploads\/2022\/07\/Tobias_Wolf_Photo.jpg?w=2079&amp;ssl=1 2079w, https:\/\/i0.wp.com\/cirpicme.org\/wp-content\/uploads\/2022\/07\/Tobias_Wolf_Photo.jpg?resize=300%2C231&amp;ssl=1 300w, https:\/\/i0.wp.com\/cirpicme.org\/wp-content\/uploads\/2022\/07\/Tobias_Wolf_Photo.jpg?resize=1024%2C788&amp;ssl=1 1024w, https:\/\/i0.wp.com\/cirpicme.org\/wp-content\/uploads\/2022\/07\/Tobias_Wolf_Photo.jpg?resize=768%2C591&amp;ssl=1 768w, https:\/\/i0.wp.com\/cirpicme.org\/wp-content\/uploads\/2022\/07\/Tobias_Wolf_Photo.jpg?resize=1536%2C1182&amp;ssl=1 1536w, https:\/\/i0.wp.com\/cirpicme.org\/wp-content\/uploads\/2022\/07\/Tobias_Wolf_Photo.jpg?resize=2048%2C1576&amp;ssl=1 2048w, https:\/\/i0.wp.com\/cirpicme.org\/wp-content\/uploads\/2022\/07\/Tobias_Wolf_Photo.jpg?resize=150%2C115&amp;ssl=1 150w, https:\/\/i0.wp.com\/cirpicme.org\/wp-content\/uploads\/2022\/07\/Tobias_Wolf_Photo.jpg?w=1800&amp;ssl=1 1800w\" sizes=\"auto, (max-width: 150px) 100vw, 150px\" \/><\/td><td><strong>Name:<\/strong><br><br><strong>Affiliation:<\/strong><br><br><strong>Email:<\/strong><\/td><td>Tobias Wolf<br><br>Technische Universitaet Dortmund, Germany<br><br>tobias2.wolf@tu-dortmund.de<\/td><\/tr><tr><td><\/td><td><\/td><td><\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n","protected":false},"excerpt":{"rendered":"<p>by Tobias Wolf, Michael Fast, Dirk Biermann, Stefan Turek (Germany) Abstract The novel process strategy of discontinuous drilling of Inconel 718 was designed to reduce thermomechanical wear at the cutting edges.
