METHOD FOR MAKING MODELS USING SIMULTANEOUS CONSTRUCTION AND CAD/CAM TECHNIQUES

摘要

ABSTRACT OF THE DISCLOSUREA sturdy three-dimensional master model constructed usingCAD/CAM and N/C machine tool techniques by digitally processing surfacedata to obtain low density, unsweetened, template contour lines offsetbelow the surface on an axis normal thereto, and then simultaneouslyconstructing a rough model having a surface offset above the surface onan axis normal thereto, while developing the surface data to sweetened,high density cutter path data and then using the cutter path data to N/Cmill the rough plus model.
