HIGH SPEED CUTTING TOOL SURFACE MORPHOLOGY WHEN TURNING BT20 TITANIUM ALLOY

Abstract

The secondary structures formed on working surfaces of the cutting wedge have the mesostructural morphology and function in the dissipative mode. The article provides the analysis of the cutting tool working surfaces projection received by means of a scanning electronic microscope that shows the mechanism of secondary mesostructures forming and working. It is shown that the dissipative activity of secondary structures is defined by the structural morphology of the cutting tool working surfaces at the mesolarge-scale level and is connected with internal friction within mesoobject boundaries.
