“…In this case, the CVD coated carbide tools had a longer lifespan, which was also due to the greater thickness of the CVD coating (2 µm for the PVD coating and 18 µm for the CVD coating), as well as the existing Al 2 O 3 layer, which protects the tool from the intense abrasive process at such high temperatures. The same steel (AISI 4340) was also studied by Kene et al [16] in turning operations with TiAlN carbide multi-layered coated tools, verifying that the use of multi-layers presents economic advantages (in comparison to the same coating applied in mono-layered form) in terms of the tool's lifespan, as well as better workpiece surface finish and greater dimensional accuracy. Navas and Bengoetxea [17] also studied the machining process of AISI 4340 steel using uncoated tools and CVD coated tools, concluding that CVD coated tools lead to better surface quality and less residual stresses.…”

In the last decade, it has been common to observe a competition between coatings achieved via physical vapor deposition (PVD) and chemical vapor deposition (CVD) techniques on cutting tools used in machining processes. The tool’s substrate material can immediately condition the coating process selection. However, there are also materials capabe of adapting to any of the coating processes. Hence, the capabilities demonstrated by a given coating when created with one technique or another are usually different due to the intrinsic characteristics of each coating process, such as temperature and stress levels. In this work, to study the machining behavior of a super duplex stainless steel, PVD- and CVD-coated tungsten carbide inserts with different coatings were used in order to identify the wear mechanisms that affect each of the coatings and the workpiece’s surface quality, evaluated through different roughness parameters. The vibration level produced throughout the various tests was also registered in an attempt to associate the type of coating or insert failure with the level of vibrations generated in the CNC (Computer Numeric Control) machining spindle. This allowed us to conclude that the tools coated with TiAlN via PVD showed better wear behavior, as well as creating workpiece surfaces with less roughness. Thus, it was clear that this coating presents strong advantages in the machining of the super duplex stainless steel chosen for this work, being an innovative work due to the combination of materials used and the approach in terms of vibration analysis applied to milling.

“…Temperature measurement of the tooltip is a challenging task and it involved techniques and procedures in the unwanted material cutting process. In situ instrumentation for the measurement of temperature is difficult, as heat is generated in close vicinity of the cutting edge, and the tool is in the relative motion during the cutting [20,21]. The assessment of cutting temperature and its control is still a big challenge in particular during the machining process of the same alloys [22].…”

The present study investigates the effect of Tool Tip Temperature on crater wear of cutting inserts of ceramics in the machining of Inconel 718 with varying hardness ranges from 26 HRC to 45 HRC respectively. The effect of cutting speed on the tool-tip-temperature and crater wear has also been investigated. A series of tests were conducted to measure the tool-tip temperature during the turning process, under controllable process parameters. Aluminum -oxide ceramic (620), mixed -oxide ceramic (6050) and silicon-nitride ceramic (6190) Sandvick triangular cutting inserts were used under dry conditions of machining. It was observed, that the temperature of cutting rises monotonically due to an increase in cutting speed. Further, temperature built up on the surface near to the tooltip leads to crater wear. The significant difference was observed in crater wear for (i) varied hardness of work-piece (ii) different cutting speed and (iii) several ceramic turning inserts with fixed machining time. The al-oxide insert has shown better cutting performance low crater wear, in comparison with silicon nitride, and mixed oxide turning inserts irrespective of the hardness of work piece and also cutting speed. Further, with the increase of work piece hardness from 26 HRC to 45 HRC, i.e. 58 % of increase of hardness has a strong influence on higher temperature rise 71% at the tooltip. Further, 26 HRC possess gave better crater wear resistance.
