Muotojyrsintä

Muotojyrsintä, also known as contour milling or 3D milling, is a subtractive manufacturing process used in computer-aided manufacturing (CAM) to create three-dimensional shapes from a workpiece. It involves using a rotating cutting tool to remove material from a block of raw material, such as metal, plastic, or wood, following a precisely defined path. This path is typically generated by computer-aided design (CAD) software and then translated into machine instructions by CAM software.

The process is characterized by its ability to produce complex, curved surfaces and intricate details that are difficult or impossible to achieve with simpler milling techniques like 2D profiling. Muotojyrsintä employs various cutting strategies, including roughing passes to quickly remove large amounts of material and finishing passes to achieve the desired surface smoothness and accuracy. The choice of cutting tool, spindle speed, feed rate, and depth of cut are critical parameters that influence the efficiency and quality of the final product.

This manufacturing method is widely used in industries such as aerospace, automotive, medical device manufacturing, and mold making, where high precision and complex geometries are required. Applications include the production of engine components, prosthetic limbs, intricate molds for plastic injection, and detailed artistic sculptures. The versatility and precision offered by muotojyrsintä make it a fundamental technique in modern manufacturing.
