摘要:	This work presents a novel cutting-path planning strategy for three-axis machining of 3D scanning data. A curve-fitting algorithm is employed to fit each array of the measured data into parallel sectional curves, ensuring that the effect of measurement and form errors call be substantially reduced. The best-fitting sectional curves are then used to construct a surface of triangular meshes. A modified chord-length method is also proposed to adequately control the accuracy of the triangular meshes generated. The triangular meshes are then offset along the surface normal to obtain an offset mesh surface on which the cutting paths are planned. An effective gouging detection and removal algorithm are also proposed to prevent the machined surface from overcutting. Several computer simulation results demonstrate the feasibility of the proposed strategy.
