Th fri ndly int rfac which can calculat th contour surfac data of param tric globodial ind xing cam is d sign d through th VB programming languag . This int rfac can b us d to calculat th valu of th r l vant contour surfac points through basic param t rs input of cam and th choos- ing of motion law of cam follow r, and it will sav th fil as th format of 0 . ibl0 . Aft r that, th fil is import d into Pro/ E 3. 0 to g n rat curv and th n th curv s ar m rg d into surfac .
