Bimetallic parts are used in many industries for weight and cost reduction of workpieces working under high loads and wear. One application for this type of composite material is in automotive industry. In this work the tool wear and cutting forces in the face milling of bimetallic parts made of aluminum and cast iron were investigated. A356 and GG25 alloys that are common materials for bimetal...

In this article, a novel method for calculating the amount of flank wear that occurs during turning nickel-based superalloy Monel K500 is presented. order to determine how much worn-out insert has sustained, technique known as Modified MSER (Maximally Stable Extremal Regions) was applied it. particular piece research, algorithm referred Flank Net. When data generated by Flank-Net and analysed t...

This study presents performance analysis of in-process tool wear detection system which uses the tool-work thermo-electromotive force (E.M.F) by the measurement circuit system as a signal-gauge in face milling. Depending on the width of tool flank wear, the cutting edge signal increases according to the variations of the electrical resistance due the increase of the contact area between tool-wo...

Microlubrication minimizes the exposure of metal working fluids (MWFs) leading to an economical, safer and healthy workplace environment. In this study vegetable based lubricant is used to conduct wear analysis during end milling AISI 1018 steel using microlubrication. Solid carbide cutting tool was used with varying cutting speed and feed rate having a constant depth of cut. A full factorial e...

The experimental investigations of the tool wear in turning of EN 31 alloy steel at different cutting parameters are reported in this paper. Mathematical model has been developed for flank wear using response surface methodology. This mathematical model correlates independent cutting parameters viz. cutting speed, feed rate and depth of cut with dependent parameters of flank wear. This model is...

The current experimental study is to investigate the effects of process parameters (cutting speed, feed rate and depth of cut) on performance characteristics (surface roughness, machining force and flank wear) in hard turning of AISI 4340 steel with multilayer CVD (TiN/TiCN/Al2O3) coated carbide insert. Combined effects of cutting parameter (v, f, d) on performance outputs (Ra, Fm and VB) are e...

As a different approach to the condition monitoring of machining processes by sensor fusion, which has been of great interest over the recent time, this paper presents a novel approach of utilising a single data source to evaluate in-process the overall machining performance in finish turning. The overall machining performance includes the variations of machining performance (chip breakability,...
