Studies on Turning of Difficult-to-Machine Materials with Actively Driven Rotary Tool

Thermal aspects of spinning round insert

Abstract

Turning characteristics of austenitic stainless steel SUS304 with an actively driven rotary lathe tool is invented from the thermal aspects. The tool temperature during one revolution of this spinning tool is measured using a newly assembled two-color pyrometer. There is an optimum tool rotational speed at which the tool temperature is at a minimum with respect to the cutting conditions.
