Muotoilujyrsintä

Muotoilujyrsintä, known in English as contour milling or contour machining, is a subtractive manufacturing process used in computer-aided manufacturing (CAM) and computer numerical control (CNC) machining. It involves the removal of material from a workpiece to create a desired shape or contour. This machining strategy is often employed to create complex, three-dimensional surfaces or to finish the edges of a part with a specific profile.

The process typically utilizes a rotating cutting tool, such as an end mill, that follows a programmed path around the workpiece. The path is generated by CAM software, which translates a digital design model into a series of machine tool movements. Muotoilujyrsintä can be performed in multiple passes, with each pass removing a small amount of material to achieve the final shape. This allows for precise control over the surface finish and dimensional accuracy of the resulting part.

Common applications for muotoilujyrsintä include the manufacturing of molds, dies, aerospace components, automotive parts, and intricate artistic pieces. The versatility of the technique makes it suitable for a wide range of materials, including metals, plastics, and composites. Effective implementation of muotoilujyrsintä requires careful consideration of tool selection, cutting parameters such as speed and feed rate, and the overall machining strategy to optimize efficiency and prevent tool wear or workpiece damage.
