  The computational consuming and non-robust reconstruction from point clouds
to either meshes or spline surfaces motivates the direct tool path planning for
point clouds. In this paper, a novel approach for planning iso-parametric tool
path from a point cloud is presented. The planning depends on the
parameterization of point clouds. Accordingly, a conformal map is employed to
build the parameterization which leads to a significant simplification of
computing tool path parameters and boundary conformed paths. Then, Tool path is
generated through linear interpolation with the forward and side step computed
against specified chord deviation and scallop height, respectively.
Experimental results are given to illustrate effectiveness of the proposed
methods.
