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...

Metal deposition at the tool flank wear-land during machining is a common phenomenon, especially in machining aluminum alloys and annealed teels. The cause of metal deposit has not been studied and the characteristics of the wear-land and deposit contact are not completely known. In his study, a turning test was conducted using tungsten carbide (WC) tools with pre-generated wear-land to machine...

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...

Cryogenic treatment has been acknowledged by some as means of extending tool life of many cutting tool materials, thus improving productivity significantly. However real mechanisms which guarantee better tool performance are still dubious. This implies the need of further investigations in order to control the technique more significantly. Studies on cryogenically treated HSS tools show microst...

This paper introduces a method to determine the tool wear by measured cutting force in Ball-nose End Milling. The features will be extracted from the measured cutting force with different flank wear. As the adaptive window width in wavelet transform is an advantage for analyzing and monitoring the rapid transient of small amplitude of cutting force signals when cutting engagement changes along ...

Noteworthy results have been obtained in the turning and drilling of hardened high-strength steels using tungsten carbide based cutting tools. In a finish turning process, it was seen that surface roughness and tool flank wear followed very different trends against cutting time. The suggested explanation for this behaviour is that the profile cut into the workpiece surface is determined by the ...

In the present work Taguchi method is used to optimize cutting parameters during dry turning of AISI 304 austenitic stainless steel with AlTiCrN coated tool. The coating was deposited on fine-grained K-grade (ISO K-20) cemented carbide cutting insert using physical vapor deposition (PVD) technique. The turning parameters evaluated are cutting speed of 200 and 260 m/min, feed rate of 0.20 and 0....

In this research work an attempt has been made to minimize flank wear of uncoated carbide inserts while machining AISI 1045 steel by finite element analysis. Tool wear is the predominant factor that causes poor surface finish and is responsible for the dimensional accuracy of the machined surface. The quality of component produced decides the effectiveness and competitiveness of any manufacturi...
