Abstract:
The analytical analysis of flat drills stability variation at opening processing in structural steels is considered. The technique and software for research, of tools stability variation by method of simulation modeling is developed. It is shown that at given modes of processing, average value of stability decreases with ascending of bars hardness variation level. the received expression allows to determine quantity of openings ?? drilling by one tool before its blunting at a variation of hardness of material of raw material by the set distribution law and at the set modes of cutting of ?1 and ?1
