Method for making models using simultaneous construction and CAD/CAM techniques

摘要

A sturdy three-dimensional master model constructed using CAD/CAM and N/C machine tool techniques by digitally processing surface data to obtain low density, unsweetened, template contour lines offset below the surface on an axis normal thereto, and then simultaneously constructing a rough model having a surface offset above the surface on an axis normal thereto, while developing the surface data to sweetened, high density cutter path data and then using the cutter path data to N/C mill the rough plus model.
