Exam Cutting Machine Operator (Summer 2025 Turning/Milling)
Cutting Machine Operator Exam Summer 2025 – done!
The Cutting Machine Operator Exam is a specialized certification (IHK) in Germany that assesses both practical and theoretical skills in CNC machining.
Want to take a closer look at the exam?
On our YouTube channel, you can find 3D simulations of the workpieces (turning & milling) from the written part of this exam – including brief explanations of the individual steps. This gives you a clear idea of what the parts look like and what was expected in the exam.
Please note: This exam and the related content are specific to the German vocational training system and may differ from similar certifications in other countries.
Subscribe to our YouTube channel for more practical CNC content:
Turning:
- In turning, the focus was on several typical machining operations, including facing and longitudinal turning of the outer contour, roughing and finishing of the inner contour, as well as threading an internal thread M36 with a 1.5 mm pitch. Additionally, a 24 mm hole was drilled.
Please note: The video are only available in German.
