A Study on the Thermal Crack Resistivity of the Cutting Tool (1st Report)

Theoretical Analysis of Transient Cutting Temperature in Turning

Abstract

Transient cutting temperature in interrupt cutting has been studied with the aim to evaluate the thermal crack resistivity of the cutting tool materials. Transient temperature distribution inside the tool, which governs thermal stresses and consequently thermal cracks, has been theoretically analyzed and formulated to the simple algebraic equation. The calculated transient temperatures of the tool surface by this equation have the good agreements with those obtained experimentally.
