Wear and Tool Life Investigation of Carbide Inserts while Hard Machining of Armox 500 Steel

Abstract

Presented article deals about the experimental investigation of PVD coated cutting inserts of type SNHF 120408EN-SR-M1while hard face milling of steel Armox 500. This study was supported by the Slovak Research and Development Agency under the contract No. APVV-15-0710. All realized measurements and tests have been performed at Department of Engineering in Trencin. It also includes support and cooperation with the University of Defence in Brno, Department of mechanical engineering. The main aim of this experimental work is to focus measurement on the influence of the various values of feed rates per tooth during the hard machining experiments of steel Armox 500. All tested workpiece material is investigated with variable cutting conditions of feed rate per tooth, whereas the cutting speed and depth of cut were specified as the constant cutting parameters. Practical part of presented work also includes some figures of worn flank faces of carbide cutting inserts, microstructure of workpiece material and graphical dependences of tool wear and tool life curve in logarithm graph as the results of these realized experimental investigation.
