A CNC Direct Interpolation Algorithm based on NURBS and its Error Analysis
For free-form surfaces or curves, it is not the best choice to use traditional G01 or G02 interpolation to generate the reference motion trajectory. Direct interpolation method is a better choice. Direct interpolation is more useful in a free-curve/surface dedicated Computer Numerical Control (CNC) system. A free-curve/surface dedicated CNC system just needs curve/surface information as input, not as a conventional CNC system uses G code as its input. NURBS (Non-Uniform Rational B-spline) is adoi:10.21203/rs.3.rs-1378144/v1 fatcat:o6mp25n7hbcq3mh6jp6pugdg4i
