CNC Programming

Numerical control (NC) refers to the automation of machine tools that are operated by abstractly programmed commands encoded on a storage medium, as opposed to controlled manually via handwheels or levers, or mechanically automated via cams alone. The first NC machines were built in the 1940s and 1950s, based on existing tools that were modified with motors that moved the controls to follow points fed into the system on punched tape.

 G00 Positioning
                                             The G00 command moves a tool to the position in the work piece system specified with in an absolute or an incremental command at a rapid traverse rate.
v                                                                      
  •                 In the absolute command, coordinate value of the end point is   programmed.
  • v        In the incremental command the distance the tool moves is programmed.
