Materiaalinpoisto

Materiaalinpoisto, often translated as material removal or subtractive manufacturing, refers to processes that shape objects by removing excess material. This is in contrast to additive manufacturing, where material is added to build up a desired shape. Common methods of materiaalinpoisto include machining, cutting, grinding, drilling, and etching.

Machining is a broad category encompassing techniques like turning, milling, and shaping, which use tools to cut away material. Turning involves rotating a workpiece while a cutting tool is advanced against it. Milling uses a rotating cutter to remove material from a stationary workpiece. Cutting processes, such as sawing and shearing, are used to divide materials. Grinding employs abrasive wheels to remove material and achieve a smooth surface finish or precise dimensions. Drilling creates holes in a workpiece. Etching, often used with chemicals or lasers, selectively removes material from a surface.

The choice of materiaalinpoisto method depends on factors such as the material being worked, the desired shape and precision, the required surface finish, and the production volume. These techniques are fundamental to many industries, including manufacturing, automotive, aerospace, and electronics, for creating components with specific geometries and tolerances. Understanding and applying materiaalinpoisto processes are crucial for product development and production.
