Aineenpoistomenetelmä

Aineenpoistomenetelmä, known in English as "material removal process" or "subtractive manufacturing," refers to a group of manufacturing techniques where material is intentionally removed from a larger piece of stock to achieve a desired shape or form. This is in contrast to additive manufacturing, where material is added layer by layer.

Common examples of aineenpoistomenetelmä include machining processes such as turning, milling, drilling, and grinding. These methods utilize cutting tools with specific geometries to shear or abrade away material. Other methods involve erosion, such as electrical discharge machining (EDM) or laser cutting, where material is removed through electrical sparks or focused beams of light, respectively. Chemical etching and abrasive waterjet cutting are also considered material removal processes.

The selection of a specific aineenpoistomenetelmä depends on several factors, including the material being worked on, the desired precision and surface finish, the complexity of the shape, and economic considerations such as cost and production volume. These methods are fundamental to many industries, enabling the production of precise components for everything from automotive parts to intricate electronic devices.
