Metallschnitte

Metallschnitte is a German-language term that refers to the processes and operations used to separate, shape or remove material from metal workpieces by cutting. It encompasses a broad group of subtractive manufacturing techniques, including traditional mechanical methods (sawing, milling, turning, drilling, shearing), thermal processes (laser cutting, plasma cutting, oxy-fuel cutting), abrasive methods (waterjet cutting, grinding) and non-conventional techniques (electrical discharge machining).

The choice of Metallschnitte method depends on material properties, required geometry, tolerances, surface finish, production volume and cost. Key process parameters include cutting speed, feed rate and depth of cut, which influence tool wear, heat generation and part quality. Advances in computer numerical control (CNC), high-speed machining, fiber lasers and automation have increased precision and productivity while reducing cycle times and manual labor.

Challenges associated with Metallschnitte include tool degradation, thermal distortion, burr formation and the need for chip and waste management. Safety considerations focus on guarding, fume extraction, heat and spark control, and proper handling of cutting fluids. Environmental and economic trends have encouraged adoption of dry machining, minimum quantity lubrication, energy-efficient equipment and hybrid manufacturing that integrates additive and subtractive steps. As a foundational set of industrial techniques, Metallschnitte remains central to metalworking, toolmaking and fabrication across automotive, aerospace, construction and general manufacturing sectors.
