CAD/CAM-EINRICHTUNG

摘要

A CAD/CAM apparatus is adapted such that each set of machining process information representative of machining attributes and the relative machining path and the order of machining are stored in a storage portion associated with each geometric element of each shape of an object, and the machining process information can be modified according to the need and stored again by a machining process edition portion, whereby it is made possible to input information relative to specifications of machining methods in an interactive manner with the display screen. The apparatus is further adapted such that NC data for machining a geometric shape are generated based on the information stored in its storage portion, whereby, differing from prior art apparatuses, it is enabled, even when there are mixed particular specifications of machining conditions for individual part of a geometric shape of the object and a common specification of machining conditions for a unit of geometric shape of the object, to output the NC data for all the shapes in a lump. Further, it is adapted such that any desired portion of the sets of machining process information stored in the storage portion associated with geometric elements can be selectively modified in the machining process edition portion so that new NC data based on the modified machining process information are provided, thereby eliminating the need for re-defining geometric shapes over again in contrast with the prior art apparatuses and enabling the NC data incorporating the modified machining process information to be formed easily and quickly.
