Type and quality of cutting chips of a drilled hole in titanium alloy
The analysis of the influence of geometry of a cutting edge of a drill on the quality of surface is resulted at drilling of titanium alloy. It is shown that drilling of materials of one chemical compound there is dependence between a deviation from cylindrical shape and the type of cutting chips produced. Dependence between a root-mean-square deviation of the hole profile and a kind of cross-section of the cutting edge is obtained. The presented results raise quality of processing and reduce labor-intensiveness of drilling of titanium alloys.
