abstract: the lifetime of a cutting tool is an important and determinant parameter for evaluating its performance. the amount of tool abrasion affects seriously dimensions and surface quality of the working piece so that one of the main factors to determine the lifetime of a tool is the level of its wearing. for this purpose, an abrasion standard is defined for each particular tool above which ...

17-4ph stainless steel is a martensitic precipitation hardening stainless steel that provides an outstandingcombination of high strength, good corrosion resistance, good mechanical properties, good toughness in both base metal and welds, and short time, low-temperature heat treatments that minimize warpage and scaling. this valuable alloy is widely used in the aerospace, nuclear, chemical, petr...

This study focused on the evaluation of the machinability of different carburising steel grades by using a cemented carbide cutting tool during semi finishing of steel. The effect of the steel composition, microstructure and inclusion characteristics on the cutting tool wear in the soft part turning was evaluated for a reference steel R (0.028% S, 0.0009% O), a clean C steel (0.003% S, 0.0005% ...

In view of the unstable cutting problem in the process of high speed milling hardened steel. Conduct experiment of the stability of machine tool and high speed milling cutter. The machine tool spindle vibration spectrum and vibration acceleration signal under the condition of different centrifugal force were detected. Obtained the critical speed of security and stability cutting of milling cutt...

In this research work a series of tests were conducted in order to determine flank wear and cutting force FY on hard AISI 440 C martensitic stainless steel and SCM 440 alloy steels. The operating parameters are cutting speed, feed rate and a constant depth of cut to investigate the flank wear and cutting force. No cutting fluid was used during the turning process. The cutting tool used was CBN ...

-AISI D3 tool steel is a high-carbon, highchromium, oil-hardening tool steel that is characterized by a relatively high attainable hardness and numerous, large, chromium-rich alloy carbides in the microstructure. These carbides provide good resistance to wear from sliding contact with other metals and abrasive materials. Typical applications for D3 tool steel include Blanking, stamping, and col...
