  2. M code - Wikipedia

    en.wikipedia.org/wiki/M_code

    M code or M-Code may refer to: Machine code; MATLAB programming language; M-code, GPS signals for use by the military; M Code, used in conjunction with G-code in the CNC/machining industry; M Formula language, sometimes called M code, a mashup query language used in Microsoft's Power Query

  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. Milling (machining) - Wikipedia

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

    These machines have developed from the basic NC (NUMERIC CONTROL) machines. A computerized form of NC machines is known as CNC machines. A set of instructions (called a program) is used to guide the machine for desired operations. There are over 100 different G-codes and M-codes. [8] Some very commonly used codes, which are used in the program are:

  5. Engineering drawing abbreviations and symbols - Wikipedia

    en.wikipedia.org/wiki/Engineering_drawing...

    Same definition as the bolt circle diameter BHCS: button head cap screw: Like an SHCS but with a button head. BHN: Brinell hardness number: BoM or BOM: bill of materials: Also called a list of materials (LM or L/M). Overlaps a lot in concept with a parts list (PL or P/L). There is no consistently enforced distinction between an L/M, a BoM, or a ...

  6. 2.5D (machining) - Wikipedia

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

    The code for 2.5D machining is significantly less complex than 3D contour machining, and the software and hardware requirements are (traditionally) less expensive. 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 ...

  7. Machine coordinate system - Wikipedia

    en.wikipedia.org/wiki/Machine_coordinate_system

    [1] In the manufacturing industry, with regard to numerically controlled machine tools, the phrase machine coordinate system refers to the physical limits of the motion of the machine in each of its axes, and to the numerical coordinate which is assigned (by the machine tool builder) to each of these limits. CNC Machinery refers to machines and devices that are controlled by using programmed ...

  8. 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.

  9. Direct numerical control - Wikipedia

    en.wikipedia.org/wiki/Direct_numerical_control

    Direct numerical control (DNC), also known as distributed numerical control (also DNC), is a common manufacturing term for networking CNC machine tools.On some CNC machine controllers, the available memory is too small to contain the machining program (for example machining complex surfaces), so in this case the program is stored in a separate computer and sent directly to the machine, one ...
