2. Milling (machining) - Wikipedia

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

   Most CNC milling machines (also called machining centers) are computer controlled vertical mills with the ability to move the spindle vertically along the Z-axis. This extra degree of freedom permits their use in diesinking, engraving applications, and 2.5D surfaces such as relief sculptures.

3. 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]

4. 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.

5. Part program - Wikipedia

   en.wikipedia.org/wiki/Part_program

   The part program is a sequence of instruction that describe the work that is to be done to a part. Typically these instructions are generated in Computer-aided manufacturing software and are then fed into the computer numerical control (CNC) software on the machines, such as drills, lathes, mills, grinders, routers, that are performing work on the part.

6. 2.5D (machining) - Wikipedia

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

   Drilling and tapping centers are inexpensive, limited-duty machining centers that began as a 2.5-axis market category, although many late-model ones are 3-axis because the software and hardware costs have dropped with advancing technology. CNC(computer numerical control) routers are another example of machines that use 2.5 axes. Routers ...

7. Digital modeling and fabrication - Wikipedia

   en.wikipedia.org/wiki/Digital_modeling_and...

   CNC machines are classified according to the number of axes that they possess, with 3, 4 and 5 axis machines all being common, and industrial robots being described with having as many as 9 axes. CNC machines are specifically successful in milling materials such as plywood, plastics, foam board, and metal at a fast speed. CNC machine beds are ...
