Evaluation method for slicing 3D vector model
3D矢量模型切片方案评价方法

To against the demerits of verifying the slicing proposal by post-estimating to finished products afterwards, this paper presented an evaluation method for the slicing proposal. It developed reconstruction algorithm of 3D vector model and path length calculation method based on two kinds of data type which were the closed contour point sets and the 2D engineering drawings. It simulated the laminated object manufacturing processes completely through plotting lines or arcs point by point and the 3D extruding layer by layer, and output the visualization model with staircase effects corresponding the different slicing proposals. Case study shows that slicing data can be reconstructed to 3D model rapidly, and the path length calculation can be used to predict total processing time. The development cost can be efficiently reduced by the valuation method.
