materiaalileikkaus
materiaalileikkaus is the Finnish term for material cutting, a fundamental process in manufacturing and fabrication that involves removing portions of a material to create a desired shape, size, or detail. It encompasses a wide range of technologies that can be broadly grouped into mechanical, thermal, and chemical methods. Mechanical cutting methods include saws, blades, shears, and rotary tools such as milling machines and CNC routers, which use blades or cutting tools to shear or chip away material. Thermal techniques, such as plasma cutting, laser cutting, and oxy-fuel cutting, generate high temperatures to melt or vaporise material along a specified path, allowing for high precision and high speed cuts on metals, plastics, and composites. Chemical methods, such as waterjet cutting, employ high-pressure abrasive-laden water to erode material through a combination of mechanical abrasion and localized heat, permitting cuts through tough or sensitive materials without causing distortion.
The choice of technique depends on material type, required tolerances, production volume, surface finish, and cost
Safety precautions are essential across all methods. Protective equipment such as goggles, gloves, and ventilation systems
