CNCFertigung

CNCFertigung refers to a manufacturing process that uses computer numerical control to operate machine tools, enabling automated, high-precision production of parts. In CNCFertigung, machine tools such as milling machines, lathes, routers, and EDMs are controlled by software that converts CAD designs into toolpaths. The result is repeatable, scalable production with tight tolerances.

Core elements include computer-aided design and manufacturing (CAD/CAM), post-processors, CNC controllers, and machine-specific tool changers. Engineers generate toolpaths or G-code from CAD models, select cutting strategy, tooling, feeds and speeds, and load programs into the machine. Setup includes fixtures, workholding, and inspection plans.

The process covers subtractive machining on a range of materials, including metals (steel, aluminum, titanium), plastics, composites, and ceramics. Capabilities include milling, turning, drilling, boring, tapping, and grinding, with multi-axis (often 3- to 5-axis) movements for complex geometries. Precision is achieved through calibration, verification cycles, and metrology.

Applications span automotive components, aerospace parts, medical devices, consumer electronics enclosures, tooling and prototyping, and spare parts. CNCFertigung is valued for accuracy, repeatability, short lead times, and the ability to produce customized or low-volume parts without tooling changes.

Limitations include high upfront capital cost, programming expertise requirements, and material constraints. Quality management systems and standards such as ISO 9001 help ensure consistency. Environmental considerations involve coolant management, chip disposal, energy use, and waste reduction. Integration with additive processes is increasingly common in hybrid manufacturing.
