<p>Profile information is input interactively without giving any particular attention to the chamfering or rounding at corners of a workpiece. After the definition of the profile is finished, the interactive screen (13a) for inputting the corner shapes is displayed (13), angles subtended by the neighbouring corner elements (EL(i), EL(i+1); (i=1,2,...) are calculated, and the intersecting angles are compared with the set angles to find the intersecting positions that can be regarded as protruding or indented corners. Under this condition, decision is made of (i) which set is collectively defined, all the corners (including protruding and indented corners), or the protruding corners alone, or the indented corners alone; and (ii) which process is done, rounding or chamfering. Then the profile information thus specified, including predetermined dimensions, are entered for the particular set of corners (either the protruding or indented corners above or both of them).</p> |
