Investigation of Chips Morphology with Tool Wear in High Speed Turning of Nickel based Super Alloy

Abstract

Nickel-based super alloys have found extensive use in the fields of aerospace, petro chemistry, marine technology, and other industries due to their outstanding corrosion resistance, oxidation resistance, stability and1reliability at various1temperatures. Even though a nickel-based super alloy is a form of treated material, cutting causes a substantial amount of cutting heat to be produced due to the contact between the tool and the work piece. The work piece's poor thermal conductivity also causes a lot of cutting heat to build up at the point of contact, which increases tool wear, shortens tool life, necessitates more frequent tool replacements, and causes other problems that drive up the company's production costs.This study covers the current status of research on failure mechanisms, tool wear optimization, etc. and discusses the mechanisms of tool1wear in the machining of nickel-based1super alloys (abrasive wear, adhesive wear, plastic deformation, chemical wear, etc.). According to a review of the literature, the goal of incorporating tool1coatings, optimising tool materials and cutting parameters, or enhancing the cutting environment is to control the heat during the processing1of nickel-based super alloys in order to improve the tool environment and lengthen tool1life. The prospects for avoiding tool wear while machining nickel-based alloys are also highlighted.
