Machine tool - Wikipedia
A machine tool is a machine for handling or machining metal or other rigid materials, usually by cutting, boring, grinding, shearing, or other forms of deformations.Machine tools employ some sort of tool that does the cutting or shaping. All machine tools have some means of constraining the work piece and provide a guided movement of the parts of the machine.
Machining - Wikipedia
Machining is a process in which a material (often metal) is cut to a desired final shape and size by a controlled material-removal process. The processes that have this common theme are collectively called subtractive manufacturing, in contrast to additive manufacturing, which uses controlled addition of material.Exactly what the "controlled" part of the definition implies can

Lathe Machine: Definition, Parts, Types, Operation,
Lathe Machine Introduction: Lathe machine is probably the oldest machine tool know to mankind. Its first use date back to 1300 BC in Egypt. The first lathe was a simple Lathe which is now called a two-person lathe. In this one person would turn the wood workpiece using rope and the other person would shape the workpiece using a sharp tool.

The lathe is a very versatile and important machine to know how to operate. This machine rotates a cylindrical object against a tool that the individual controls. The lathe is the forerunner of all machine tools. The work is held and rotated on its axis while the cutting tool is advanced along the line of a desired cut.
Operation Performed On Milling machine With Diagrams
Spur, helical gears are cut on a milling machine with the help of an indexing mechanism. The operation of gear cutting is cutting of equally spaced, identical gear teeth on a gear blank by handling it on a universal dividing head and then indexing it. The cutter used for this operation is cylindrical type or end mill type.
