| Abstract: | A novel approach of representation and process planning for solid freeform fabrication of FGM objects,termed as iso-composition contour Line/Face,is proposed based on STL solid model.In this model,the material information is associated with a series of 2D layers which an arbitrary 3D CAD model is adaptively sliced into.Whereafter,within each layer,continuous distribution of material information is discretized into iso-composition contour lines or faces,which can be used for subsequent path planning.Finally,a functionally Graded train wheel is presented to demonstrate the representation and path-planning facing to Direct Plasma Deposition. |
