jyrsintöjä

Jyrsintöjä, often translated as "milling" in English, refers to a subtractive manufacturing process used to shape materials. In this process, a rotating cutting tool removes material from a workpiece to create a desired shape. The workpiece is typically held stationary or moved linearly, while the cutting tool, also known as a mill or cutter, rotates at high speeds. The relative motion between the tool and the workpiece allows for the precise removal of material, enabling the creation of complex geometries.

There are various types of milling operations, distinguished by the orientation of the cutting tool and the workpiece. Common forms include face milling, where the cutting face of the tool is parallel to the surface being machined, and peripheral milling, where the cutting occurs along the circumference of the tool. Milling can be performed on a wide range of materials, including metals, plastics, and wood. The process is widely used in industries such as automotive, aerospace, and mold making due to its versatility and ability to achieve high precision and surface finish.

The machinery used for milling is called a milling machine. These machines can be manual, where the operator controls the movement of the workpiece and/or the cutter, or automated, often controlled by computer numerical control (CNC) systems. CNC milling allows for highly repeatable and complex machining operations with minimal human intervention. The choice of cutting tool, its material, speed, and feed rate are critical factors that influence the efficiency and quality of the milling process.
