TL;DR: In this article, a neural network-based sensor fusion model has been developed for tool condition monitoring (TCM), where features extracted from a number of machining zone signals, namely cutting forces, spindle vibration, spindles current, and sound pressure level have been fused to estimate the average flank wear of the main cutting edge.
Journal ArticleDOI
Growth of tool wear in turning of Ti-6Al-4V alloy under cryogenic cooling
TL;DR: In this paper, the tool wear and tool life of uncoated carbide cutting tool inserts in machining of Ti-6Al-4V alloy have been studied under dry, wet and cryogenic cooling environments.
Journal ArticleDOI
Beneficial effects of cryogenic cooling over dry and wet machining on tool wear and surface finish in turning AISI 1060 steel
TL;DR: In this paper, the role of liquid nitrogen jet on tool wear and surface finish was investigated in plain turning of AISI 1060 steel at industrial speed-feed combination by two types of carbide inserts of different geometric configurations.
Journal ArticleDOI
Tool wear in cryogenic turning of Ti-6Al-4V alloy
TL;DR: In this paper, the effects of liquid nitrogen cooling on growth and nature tool wear were investigated for turning Ti-6Al-4V alloy bars with micro-crystalline uncoated carbide inserts under dry, wet and cryogenic cooling environments in the cutting velocity range of 70-100m/min.
Journal ArticleDOI
The influence of cryogenic cooling on tool wear, dimensional accuracy and surface finish in turning AISI 1040 and E4340C steels
TL;DR: In this paper, the role of liquid nitrogen jet on tool wear and product quality in plain turning of AISI 1040 and E4340C steel at industrial speed-feed combinations by two types of carbide inserts of different geometry was investigated.
