Effect of Cutting Parameters on Tool Life

Abstract

In metal cutting operations, it is desirable to study the tool wear, dimensional accuracy, surface roughness and the cutting parameters that affect the tool life. Flank wear of cutting tools is often considered as the tool life criterion because it determines the diametric accuracy of machining, its stability and reliability. The present work shows how the life of the cutting tool can be calculated taking into account the cutting parameters such as cutting speed, feed and depth of cut, workpiece material, power of the machine, the dimensional tolerance of the part, the geometry of the cutting tool, operating conditions of the machine tool and the finishing surface etc. The tool life of cutting tool insert was investigated by the dimensional tolerance set for the workpiece. In order to study the tool life, model of cutting tool insert is built by the Pro-e Wildfire 5.0, and model file is imported into ANSYS Workbench 14.5 software so as to carry out the post-processing by the finite element and subsequently tool life is analyzed.
