Cutting tool life is reduced remarkably in machining steel with High speed steel (HSS) tools at high cutting speeds and feed rates. Due to poor cutting characteristics with the uncoated HSS tool, tool life is short and good surface finfish cannot be obtained in many cases. Therefore, the cutting characteristics can be improved by using Physical Vapour Deposition (PVD) coated cutting tool. In the present study, HSS single point cutting tool was coated with TiN, AlCrN and TiAlN by PVD method (Derlikon Blazer Ltd.).The cutting characteristics of TiN, AlCrN and TiAlN coated tools are investigated by measuring cutting force and hardness. © 2017 Elsevier Ltd.

Cutting performance and wear mechanism of Ti–Al–N/Al–Cr–O coated silicon nitride ceramic cutting inserts

Hard turning with multilayer coated carbide tool has several benefits over grinding process such as, reduction of processing costs, increased productivities and improved material properties. The objective was to establish a correlation between cutting parameters such as cutting speed, feed rate and depth of cut with machining force, power, specific cutting force, tool wear and surface roughness on work piece. In the present study, performance of multilayer hard coatings (TiC/TiCN/Al 2O 3) on cemented carbide substrate using chemical vapor deposition (CVD) for machining of hardened AISI 4340 steel was evaluated. An attempt has been made to analyze the effects of process parameters on machinability aspects using Taguchi technique. Response surface plots are generated for the study of interaction effects of cutting conditions on machinability factors. The correlations were established by multiple linear regression models. The linear regression models were validated using confirmation tests. The analysis of the result revealed that, the optimal combination of low feed rate and low depth of cut with high cutting speed is beneficial for reducing machining force. Higher values of feed rates are necessary to minimize the specific cutting force. The machining power and cutting tool wear increases almost linearly with increase in cutting speed and feed rate. The combination of low feed rate and high cutting speed is necessary for minimizing the surface roughness. Abrasion was the principle wear mechanism observed at all the cutting conditions. © 2012 Published by Elsevier Ltd. All rights reserved.
