2. 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.

3. Machining - Wikipedia

   en.wikipedia.org/wiki/Machining

   Milling operations are operations where the cutting tool with cutting edges along its cylindrical face are brought against a workpiece to remove material in the profile of the spinning tools shaft and lower edge. [7] Milling machines are the principal machine tool used in milling. Advanced CNC machines may combine lathe and milling operations.

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. Speeds and feeds - Wikipedia

   en.wikipedia.org/wiki/Speeds_and_feeds

   Cutting speed may be defined as the rate at the workpiece surface, irrespective of the machining operation used. A cutting speed for mild steel of 100 ft/min is the same whether it is the speed of the cutter passing over the workpiece, such as in a turning operation, or the speed of the cutter moving past a workpiece, such as in a milling operation.

6. Canned cycle - Wikipedia

   en.wikipedia.org/wiki/Canned_cycle

   A, B, C and D are used for Rectangular pocket machining. A= Machining allowance; B= Step over; C= Step depth; D= Additional depth of cut for first pass; G80 is used for cancelling the currently selected canned cycle as G-codes for canned cycles are modal. If the machine control supports it, the user may create their own custom canned cycles.

7. 2.5D (machining) - Wikipedia

   en.wikipedia.org/wiki/2.5D_(machining)

   Drilling and tapping operations are also possible on a 2.5-axis mill. 2.5D objects can be machined on a 3-axis milling machine, and do not require any of the features of a higher-axis machine to produce. CNC machines use G-code and M-code in order to control the machine and the positioning of the spindle.

8. Computer-aided manufacturing - Wikipedia

   en.wikipedia.org/wiki/Computer-aided_manufacturing

   This process usually begins with raw stock, known as billet, or a rough casting which a CNC machine cuts roughly to shape of the final model, ignoring the fine details. In milling, the result often gives the appearance of terraces or steps, because the strategy has taken multiple "steps" down the part as it removes material. This takes the best ...

9. Machinist - Wikipedia

   en.wikipedia.org/wiki/Machinist

   A competent machinist should have a well-developed mechanical aptitude, the ability to correctly use precision measuring instruments and to interpret blueprints, and a working knowledge of the proper parameters required for successfully utilizing the various tools commonly used in machining operations. CNC (computer numerical control) is the ...
