Abstract
In order to further reflect the advantages of NURBS curve interpolation, obtaining reliable NURBS curve format tool path by NURBS curve fitting for continuous short line segments can be a general way to optimize the tool path. The NURBS curve fitting method of the continuous short line segments path proposed in this paper is divided into two stages, that is, the segmentation stage of the cutter location data and the NURBS curve fitting stage. The segmentation stage is based on the corner feature including the corner angle test and the test of the double chord error. The NURBS curve fitting stage based on least square method provides the parameterization of the tool path data points and the node partition strategy, and controls the fitting error effectively. Through the experimental research of the test case, a good fitting effect is obtained, and the simulation results are compared with those by the direct transition method, which prove the validity of this method.
