G-code (abbreviation for geometric code; also called RS-274 [citation needed]) is the most widely used computer numerical control (CNC) and 3D printing programming language. It is used mainly in computer-aided manufacturing to control automated machine tools, as well as for 3D-printer slicer applications. G-code has many variants.
APT is used to program numerically-controlled machine tools to create complex parts using a cutting tool moving in space. It is used to calculate a path that a tool must follow to generate a desired form. APT is a special-purpose language and the predecessor to modern computer aided manufacturing (CAM) systems. It was created and refined during ...
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]
Canned cycles are so called because they allow a concise way to program a machine to produce a feature of a part. [2] A canned cycle is also known as a fixed cycle . A canned cycle is usually permanently stored as a pre-program in the machine's controller and cannot be altered by the user.
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:
While G-code is the most common method of programming, some machine-tool/control manufacturers also have invented their own proprietary "conversational" methods of programming, trying to make it easier to program simple parts and make set-up and modifications at the machine easier (such as Mazak's Mazatrol, Okuma's IGF, and Hurco).
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.
CAM systems generate the G-Code commands (NC program) for the CNC machine. Geometry, description and cutting conditions are selected and received directly from tool management. This ensures that all tools used are documented and consistent with the reality in the workshop.
