What is a coordinate system?
Posted by on 26 June 2015 02:10 PM

A CNC machine is controlled by commanding movements to, and tracking the positions of the axes. These movements are defined in terms of a coordinate system. Mach3/Mach4 uses multiple sets of (Cartesian) coordinate systems for various tasks. The Machine Coordinate (G53) system is the base system that all of the other fixture/work/tool offsets are relative.
