Milling (machining) - Wikipedia
Milling is the process of machining using rotary cutters to remove material by advancing a cutter into a workpiece.This may be done varying direction on one or several axes, cutter head speed, and pressure. Milling covers a wide variety of different operations and machines, on scales from small individual parts to large, heavy-duty gang milling operations.

The first ordinary milling machine (Whitney, 1818). In 1818, Whitney made the world's the first ordinary milling machine, but the patent of the milling machine is "get" by the British Bodmer (inventor of gantry planer with the knife device) in 1839. As the milling machine high cost, there are not much interested.
A disk tool cutting method for bevel gear manufacture on a ...
Two main popular cutting methods for bevel gear mass production, face milling and face hobbing, both require dedicated tools and machines available from only a few machine tool companies, which makes production more costly. This paper thus proposes a cheaper, more flexible alternative for producing small or medium batches of large bevel gears, a disk tool cutting method …
Gear cutting (gear manufacturing) - tec-science
Form cutting of gears (milling) can be performed on ordinary milling machines. Special disc cutters are required for each module (diametral pitch) and each number of teeth! Gear broaching. Broaching is similar to shaping or planing in terms of motion. However, a broaching tool has several cutting edges arranged one behind the other.

machine tool - Modifications of basic machines | Britannica
Gear-cutting machines. Three basic cutting methods are used for machining gears: (1) form cutting, (2) template cutting, and (3) generating. The form-cutting method uses a cutting tool that has the same form as the space between two adjacent teeth on a gear. This method is used for cutting gear teeth on a milling machine.

With gashing, the gear wheel is held steady while a milling cutter advances axially along the face width of the gear blank. This process can be used to rough or semi-finish the tooth space with extra stock allowance for successive hobbing, grinding, shaving, or honing operations. Or, it can complete the tooth space to final form.
