Milling cutters are an essential component of a milling machine. As the name suggests, it is the cutting tool responsible for scraping the material outside the workpiece. All milling machines have a cutter. During a typical milling operation, the Cutter moves perpendicular to its axis, allowing it to remove material from the workpiece at the perimeter of the Cutter.

As a result the cutting force also varies from zero to the maximum value per tooth movement of the milling cutter. The major disadvantages of the upmilling process are the tendency of cutting force to lift the work from the fixtures and poor surface finish obtained. But being a safer process, it is a commonly used method of milling.

5) Power consumption. Power consumed in feed motion: up milling is higher than forward milling. Under the same cutting condition, the power consumption of down milling is 5% 15% lower. 6)Chip removal: down milling is more suitable for chip management. Down milling is a general choice to improve surface finish and ensure the accuracy.

Manual milling is a relatively slow and laborintensive process, and is generally used for lowvolume production or prototyping. One of the main limitations of manual milling is its low productivity. Manual milling is a slow process, and it can take a long time to produce a single part. This makes it unsuitable for highvolume production.

Face mills are tools with a large diameter that are used to cut a wide shallow path for facing operations. Facing is used for machining a large flat area, typically the top of the part in preparation for other milling operations. A face mill is a solid body that holds multiple carbide inserts that can be replaced as they wear out.
