| Abstract: | A mathematical procedure for finding the contact points of shaping arcs at the end of a punch is considered. Profiling of the conical upper section of a punch is discussed. A golden-section algorithm is proposed for determining an angle whose value cannot be determined analytically from the initial data. |
