Влияние величины переднего и заднего угла спирального сверла на силу резания при сверлении отверстий в литейных алюминиях

Abstract

In the article there giver the results of investigations about the determining the effect of quantity of front and back angles standard spiral drill with elements of grinding cut on cutting force and friction force at drilling deep holes in casting aluminum alloys on modular machines. The conclusions about reduction of cutting force and friction force in dependence on quantity of angles and cutting mode are made.
