Perspective drilling methods, holes

Abstract

The article deals with the issues of improving the productivity and quality of drilling holes. The results of systematization and introduced into production methods of drilling with changing cutting modes during insertion and entry of the drill, grinding of descending chips and removal of it and the cutting zone are developed, tool materials, coolant compositions are promising, cutting modes are optimal, a mathematical model of the influence of modes and methods of drilling on hole accuracy and quality. An algorithm of the proposed drilling methods for machine tools with program control has been compiled.
