Sivujyrsimissä

Sivujyrsimissä, which translates to "side milling" in English, is a machining process used in subtractive manufacturing. It involves using a milling cutter whose diameter is greater than its width, allowing the cutting to occur on the side of the cutter's circumference. Unlike face milling, where the tool cuts with its end, side milling utilizes the periphery of the cutting tool. This technique is versatile and can be employed to create various features on a workpiece, such as slots, grooves, pockets, and shoulders.

The process typically involves a rotating milling cutter that moves across the surface of a stationary or moving workpiece. The depth of the cut is determined by how deeply the side of the cutter is engaged with the material. Different types of side milling cutters exist, including slab mills, slotting cutters, and side and face cutters, each designed for specific applications. The choice of cutter, along with cutting speed, feed rate, and depth of cut, influences the surface finish, accuracy, and efficiency of the operation. Side milling is a fundamental technique in milling operations, enabling the creation of complex geometries and precise features in a wide range of materials.
