Abstract

The machinability of Nickel-based superalloy GH4169 is poor, in order to improve machining efficiency, reduce costs, it is necessary to study the various factors that affect the tool wear. In this paper.The tool wear tests were carried out to investigate the effect of an externally applied voltage on insert flank wear in turning of Ni-based superalloy GH4169 with coated carbide tool YBG202. Flank wear morphology was observed and the VB values were measured. The result showed that the applied voltage affected the tool wear obviously, When the insert was no externally voltage applied, the flank wear was least, when the insert was cathode, the flank wear was lower than when the insert was anode. The insert wear increased as applied voltage increased. The externally applied voltage accelerated the tool wear due to serious adhesive and abrasive wear, which leaded to the cutting efficiency decreased and cost increased, so it should try to avoid applied voltage when machining nickel-based superalloy.
