Feedrate Optimization with Contouring Error and Drive ...

Abstract: Five-axis Computer Numerical Controlled (CNC) machine tools are used to machine parts with complex, curved surfaces. The tracking errors of five drives lead to path contouring errors which need to be maintained within the tolerance of the part. The contouring errors can be decreased by reducing the machining feedrate.
