3. Machinist - Wikipedia

   en.wikipedia.org/wiki/Machinist

   CNC (computer numerical control) is the modern manufacturing method in which machinist use a form of programming called G-code to make components for a wide variety of industries. CNC programming is a highly skilled position. Programmers are usually machinist as well.

4. Numerical control - Wikipedia

   en.wikipedia.org/wiki/Numerical_control

   A CNC machine that operates on wood CNC machines typically use some kind of coolant, typically a water-miscible oil, to keep the tool and parts from getting hot. A CNC metal lathe with the door open. In machining, numerical control, also called computer numerical control (CNC), [1] is the automated control of tools by means of a computer. [2]

5. Tool and die maker - Wikipedia

   en.wikipedia.org/wiki/Tool_and_die_maker

   Working from engineering drawings developed by the toolmaker, engineers or technologists, tool makers lay out the design on the raw material (usually metal), then cut it to size and shape using manually controlled machine tools (such as lathes, milling machines, grinding machines, and jig grinders), power tools (such as die grinders and rotary tools), and hand tools (such as files and honing ...

6. Machining - Wikipedia

   en.wikipedia.org/wiki/Machining

   In production machining jobs, one or more roughing cuts are usually performed on the work, followed by one or two finishing cuts. Roughing operations are done at high feeds and depths – feeds of 0.4–1.25 mm/rev (0.015–0.050 in/rev) and depths of 2.5–20 mm (0.100–0.750 in) are typical, but actual values depend on the workpiece materials.

7. Milling (machining) - Wikipedia

   en.wikipedia.org/wiki/Milling_(machining)

   The original class of machine tools for milling was the milling machine (often called a mill). After the advent of computer numerical control (CNC) in the 1960s, milling machines evolved into machining centers: milling machines augmented by automatic tool changers, tool magazines or carousels, CNC capability, coolant systems, and enclosures ...
