NEW ALGORITHM AND PROGRAM FOR SIMPLE EXTRACTION WITH MULTIPLE CONTACTS OPTIMIZATION

A mathematical algorithm and a Turbo Pascal computer program, allowing to perform some calculations for simple extraction with multiple contacts, using the Gibbs’s triangle and a new method of interpolation, simpler than the usual one, are described. The results obtained on the computer are in line with those obtained by hand execution of the graphical constructions, being confirmed by the experimental results. The depicted algorithm obviously simplifies the hand graphic construction work.
