“…For example, a TiAlN/TiN multi-layer coated cutting tool improves machining operations utilizing the anti-sticking property of TiN and the low thermal conductivity of TiAlN (Hsieh et al 1998;Thakur and Gangopadhyay 2016). Niu et al (2013) investigated the cutting process of difficult-to-cut materials using carbide inserts with various coatings. The study discussed the cutting forces, chip morphology, tool wear, and surface roughness.…”

This paper investigates the influences of three different input parameters, such as feed rate, insert nose radius, and insert coating methods, in the turning operation of Inconel 718. The coating methods were selected as medium temperature chemical vapor deposition (MT-CVD) and physical vapor deposition (PVD) and in addition to coating methods, the role of various coating materials was discussed since the inserts were coated with multi-layers of TiCN/Al2O3/TiN and single-layer of TiAlN on carbide substrates. The results were discussed in terms of wear behavior of cutting tools and surface quality of the workpiece, which is indicated by surface roughness. A full factorial experimental design was employed in the present work and the results were evaluated using main effects plots. Furthermore, the analysis of variance (ANOVA) method was applied to specify both reactive and non-reactive effects of experimental parameter reactions. The results showed that surface roughness is reduced using low feed rates and large nosed inserts in the operations. Furthermore, TiAlN-coated inserts with PVD method provided better surface finish than with MT-CVD method. It was also found that surface roughness increases as the wear rate of inserts increases.

“…The cutting tool requires properties such as resistance to wear, hot hardness, resistance to oxidation and thermal shock resistance [3,4]. In the current scenario, more research work is going on utilizing PVD and CVD nanocoatings on the cutting tools in order to improve their performance [5]. The CVD coatings have high chemical stability that needs a high temperature of around 1000°C for the process whereas PVD coatings require ionized vaporization deposition at around 500°C [6].…”

Tool life of the traditional cutting tools is comparatively lesser on machining the martensitic stainless steel AISI 416 which is one of the hardest materials. In order to increase the tool life, wear-resistant nanocoatings on the cutting tools have been explored. This study enunciates a comparison of tool life between PECVD (plasma-enhanced CVD multilayer nanocoated) and PVDMNC (PVD multilayer nanocoated) cutting tools on turning a martensitic stainless steel AISI 416 by experimental and theoretical investigations in addition to exploration of the machinability studies of cutting tool flank wear, tool hardness and surface roughness of work material. An orthogonal design, signal-to-noise ratio and Analysis of Variance (ANOVA) methods were employed to confirm the parameters like cutting speed, tool hardness and feed rate that are involved in the study to estimate the cutting toollife. The investigations confirmed that cutting speed was the most dominant factor in determining tool life while comparing with other parameters. It was observed from the ANOVA results that the cutting speed, tool hardness, and feed rate have contributed 41.44%, 33.79%, and 24.35% respectively in determining the tool life of PECVD cutting tools whereas the contributions of the same parameters were found to be 40.01%, 32.90%, and 26.63% respectively for PVDMNC cutting tool. It is evident from the results that the cutting performance of the PECVD cutting tool is superior in terms of cutting speed and hardness which were enhanced by 1.43% and 0.89% respectively in addition to lesser wear rate when compared to the performance of PVDMNC cutting tools.

“…Li et al 14 compared the cutting performance of multilayered TiAlN and AlCrN coatings on solid carbide end mills and discovered that the TiAlN was more suitable for the multilayer coating of end mill during machining Ti-6Al-4V alloy. Niu et al 15 conducted experiments and proved that physical vapor deposition (PVD)-TiN/TiAlN insert exhibited better performance in milling TC6 alloy than chemical vapor deposition (CVD)-TiN/Al 2 O 3 /TiCN insert, and adhesion and spalling dominated the wear mechanisms. When the same coated insert was used in milling of TC11 and TC17 under dry condition, TC17 alloy was suggested to machine using PVD-(TiN/TiAlN)-coated carbide insert while CVD-(TiN/Al 2 O 3 /TiCN)-coated insert was suitable for milling TC11 alloy.…”

Chip morphology and its formation mechanisms, cutting force, cutting power, specific cutting energy, tool wear, and tool wear mechanisms at different cutting speeds of 100-3000 m/min during dry face milling of Ti-6Al-4V alloy using physical vapor deposition-(Ti,Al)N-TiN-coated cemented carbide tools were investigated. The cutting speed was linked to the chip formation process and tool failure mechanisms of the coated cemented cutting tools. Results revealed that the machined chips exhibited clear saw-tooth profile and were almost segmented at high cutting speeds, and apparent degree of saw-tooth chip morphology occurred as cutting speed increased. Abrasion in the flank face, the adhered chips on the wear surface, and even melt chips were the most typical wear forms. Complex and synergistic interactions among abrasive wear, coating delamination, adhesive wear, oxidation wear, and thermal mechanical-mechanical impacts were the main wear or failure mechanisms. As the cutting speed was very high (.2000 m/min), discontinuous or fragment chips and even melt chips were produced, but few chips can be collected because the chips easily burned under the extremely high cutting temperature. Large area flaking, extreme abrasion, and serious adhesion dominated the wear patterns, and the tool wear mechanisms were the interaction of thermal wear and mechanical wear or failure under the ultra-high frequency and strong impact thermo-mechanical loads.
