Abstract:
A graphic display system to provide a graphically represented solid modeler for simulating a material removal process in a computer aided machining environment, said graphic display system comprising:at least one fundamental manufacturing entity representing a three dimensional object;profile generation means for generating at least one machine profile representing a volume of material to be removed from said at least one fundamental manufacturing entity, said machine profile is selectively defined on at least one surface of said at least one fundamental manufacturing entity by an ordered combination of edges defined by a first circular arc connected in series at a first point to a first guadric curve connected in series at a second point to a second circular arc connected in series at a third point to a straight edge connected in series at a fourth point to a third circular arc, wherein parameters defining a shape and the existence of each of said first circular arc, said first guadric curve, said second circular arc, said straight edge, and said third circular arc of said ordered combination are manipulated to define said machine profile.
