NUMERICAL ANALYSIS IN INTERRUPTED CUTTING TOOL TEMPERATURES

Pages 1-20 | Published online: 29 Oct 2010
 

Abstract

A full three-dimensional numerical analysis, using a control volume approach, is conducted to study the interrupted cutting tool temperatures with temperature dependent thermal properties. The extremely small size of the heat input zone (tool-chip interface) , relative to the tool insert rake surface area, requires the mesh to be dense enough to obtain accurate solutions. This usually requires very intensive computational efforts. An efficient numerical scheme is chosen to significantly reduce the required computing time. The effect of two different heat flux input profiles, a uniform heat flux and a parabolic heat flux, on the tool temperatures also are investigated.
