Introduction to Milling. Milling is a Substractive machining process that uses many machine toolsets to efficiently precisioncut a variety of materials (such as metals, plastics, or wood) into a defined geometrical part. Milling machines rapidly produce enduse parts by adopting 3 or 5axis processes. Metal parts offer greater finishing ...
