The NC formats were originally designed by CNC drill and route machine vendors as proprietary input formats for their equipment, and are known under their company name: Excellon, Hitachi, Sieb & Meyer, Posalux, etc. These formats are similar as they are based on RS-274-C and related to G-code. In 1985 IPC published a generic standard NC format ...
G-code (also RS-274) 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. The G stands for geometry. G-code has many variants.
The resulting file is then run by the control of the machine to generate tool motions and other machine actions. Most commonly, this file is in some form of RS-274 format instructions, commonly known as G-code .
MazaCAM is a CNC programming system [1] for the Mazak CNC (Numerical control) machine-tools (see Yamazaki Mazak Corporation [2]), sold and supported by SolutionWare Corporation. [ 3 ] MazaCAM [ 4 ] differs from most other CNC programming systems in that it can generate CNC programs in both Mazatrol [ 5 ] and G-code .
The majority of G-code programs start with a percent (%) symbol on the first line, then followed by an "O" with a numerical name for the program (i.e. "O0001") on the second line, then another percent (%) symbol on the last line of the program. The format for a G-code is the letter G followed by two to three digits; for example G01.
STEP-NC interface on a CNC, showing product shape and color-coded tolerance state. STEP-NC is a machine tool control language that extends the ISO 10303 STEP standards with the machining model in ISO 14649, [1] adding geometric dimension and tolerance data for inspection, and the STEP PDM model for integration into the wider enterprise.
