"Coordinates for the CNC Lathe" provides an overview of the coordinates used to program cutting operations on CNC lathes or turning centers. It introduces the systems of both Cartesian and polar coordinates and describes how Cartesian axes are used on a CNC lathe. The class describes both how coordinates are used on blueprints and how they are 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 lathe or turning center.
