“…Okada et al 5 have used coatings such as TiN, TiCN, TiAlN, TiAlN/AlCrN and CBN on carbide tool, to evaluate the machinability of the hardened steel (60HRC). The evaluation of the machining performance was done with respect to tool wear, cutting temperature and surface roughness.…”

In the present work, the performances of TiAlN-, AlCrN-and AlCrN/TiAlN-coated and uncoated tungsten carbide cutting tool inserts are evaluated from the turning studies conducted on EN24 alloy steel workpiece. The output parameters such as cutting forces, surface roughness and tool wear for TiAlN-, AlCrN-and AlCrN/TiAlN-coated carbide cutting tools are compared with uncoated carbide cutting tools (K10). The design of experiment based on Taguchi's approach is used to obtain the best turning parameters, namely cutting speed (V ), feed rate (f) and depth of cut (d), in order to have a better surface¯nish and minimum tool°ank wear. An orthogonal array (L 9 Þ was used to conduct the experiments. The results show that the AlCrN/ TiAlN-coated cutting tool provided a much better surface¯nish and minimum tool°ank wear. The minimum tool°ank wear and minimum surface roughness were obtained using AlCrN/ TiAlN-coated tools, when V ¼ 160 m/min, f ¼ 0:318 mm/rev and d ¼ 0:3 mm.

This study examined the wear characteristics of ceramic tools when turning BN free-machining steel based on AISI 1045. An experiment was conducted to investigate why the alumina TiC-based ceramic tool showed remarkably better cutting performance than a pure alumina ceramic tool. The tool flank temperature, cutting force, and element distribution on the wear part were investigated. The cutting force and tool flank temperature of the BN free-machining steel were lower than those of standard steel, and the alumina TiC-based ceramic tool allowed for a lower cutting force and tool flank temperature than the pure alumina ceramic tool. After cutting of the BN free-machining steel, on the rake face, a deposited layer containing Al and N was detected, and the amount of the deposited layer on the alumina TiC-based ceramic tool was more than that on the pure alumina ceramic tool. Therefore, using an alumina TiC-based ceramic tool suppresses the tool flank temperature and makes it easier for a protective nitride layer to stick on the wear part; as a result, it has a clearly superior tool wear resistance than an alumina ceramic tool.

“…The pyrometer, having a flat response from 10 Hz to 400 kHz, can be used for measurement of the tool temperature in turning with a good degree of accuracy. This pyrometer type has been successfully applied in previous studies in cutting (Tanaka, et al, 2013) and milling (Okada, et al, 2010).…”

This research deals with the hard turning of cemented carbide with CBN and diamond tools, and focuses on the tool performance, mainly tool wear with respect to cutting force and cutting temperature. The internal turning tests without cutting fluid are executed with the vertical machining center. Seven types of tool materials: SC, CVD-SC, two PCDs, BL-NPD (Binderless nano-polycrystalline diamond) and CBN: are selected for cutting three grades of cemented carbides WC having the different Co binder content (12%, 20% and 25%). Attrition has been found to be the main tool wear mechanism for all tools with slight adhesion of the workpiece binder on the tool face. In cutting of softest carbide WC-m (25% Co), the polycrystalline CBN tool has the lowest tool wear than any other PCD tools. In turning of harder carbides WC-d (20% Co) and WC-t (12% Co), both polycrystalline CBN and PCD cannot be used continuously due to their low hardness, and BL-NPD, SC and CVD-SC tools are applicable. And the BL-NPD tool has the best cutting performance with less flank wear. As for WC-d, extremely stable cutting can be done with BL-NPD where the principal cutting force is kept almost constant at 40 N. Only BL-NPD tool can continue to turn the hardest WC-t. In spite of turning hard materials, the tool temperatures measured are relatively low below 450°C due to the high thermal conductivities of tool materials. However, cutting temperature is directly related to the tool wear and cutting force rather than thermal conductivity of tool in turning of WC-m and WC-t.
