... alloys. Also, time-dependent prediction of cutting tool wear has not been addressed adequately. In this study, a theoretical model to predict tool wear in drilling as a function of time and to evaluate tool life of anti-abrasion-, TiAlSiN-, and TiAlN-coated drills are presented. Considering feed rate...
