Linear Interpolation and Chordal Deviation CNC controllers natively move in straight lines using G1 commands (Linear Interpolation) or circular arcs using G2/G3 commands (Circular Interpolation).
CNC controllers natively move in straight lines using G1 commands (Linear Interpolation) or circular arcs using G2/G3 commands (Circular Interpolation). To represent a complex curved spline or surface using G1 commands, the CAM system must divide the curve into a series of short linear chords.
