Milling is a process in which a cutting tool is rotated at high speed to remove metal and finish it into the desired shape. Also known as milling, it is a type of "removal process" in which unnecessary parts are removed from a material to create the desired shape. Removal processes can be divided into various methods, but milling is classified as a "cutting process." A machine tool called a milling machine is mainly used for this process, and the cutting tools used are called cutting tools. By using various cutting tools appropriately, it is possible to handle a wide range of processes such as flat and curved surfaces, grooves, and hole drilling.
