  cutter contact
Avoiding gouge is crucial when converting cutter contact (CC) data into cutter location (CL) data for arbitrary pockets involving islands.
      
It is based on the uniform distribution of the cutter contact points with regards to the rotation angles.
      
Current industrial practice is thus to discretize the continuous tool path into a finite number of cutter contact (CC) points.
      
Hence, the cutter contact (CC) velocity along the surface tends to vary, resulting in a nonuniform machining performance.
      
An initial tool orientation is obtained by assessing the angle of the vectors determined by data points of contours of the open region and cutter contact (CC) points.

A method for 3-axis NC rough miiling of free surfaces is proposed. Based on nonuniformrational B-spline patches , the geometric model for a workblank during rough milling is di-rectly worked out with the final part surface, Methods for the evolution of the milling lay-ers, the generation of isoparametric NC tool-path and the calculation of the error of linearapproximation are described. To avoid any interference occurring in NC machining with acylindrical end-milling cutter, an effective algorithm is developed for the calculation of inter-ference points and interference-free cutter location data. There are two steps in the algo-rithm,i.e., cutter contact points are obtained in accordance with the tolerance specified,and the tool path is then generated from the triangular polyhedron,An application is given todemonstrate the feasibility of the approach.
