Coordinates for the CNC Mill 222

Coordinates for the CNC Mill provides an overview of the coordinates used to program cutting operations on CNC mills or machining centers. It introduces the systems of both Cartesian and polar coordinates and explains the Cartesian axes for vertical and horizontal CNC mills. The class describes how coordinates are used on blueprints and applied as machine movements. This includes concepts such as incremental vs. absolute coordinates, linear and circular interpolation, machine zero, and program zero. Coordinates and axis movements are at the core of operations for a CNC machine. A foundational knowledge of these topics is necessary to understand how and why parts can be successfully made on the CNC mill or machining center.
