Application of surface modification techniques during hard turning: Present work and future prospects
2018, International Journal of Refractory Metals and Hard MaterialsCitation Excerpt :Thus, this section deals with the investigations carried out by researchers on the effect of these parameters during the hard turning process. The researchers revealed that the thickness of the coatings significantly impacts the performance of cutting tools and there is always an optimum coating thickness for a coating at which the best performance can be obtained from a coated tool [20, 31, 72, 73, 79, 80]. The strain energy and compressive stresses in the coating increase with the increase in thin film thickness and thus, making coatings more susceptible to chipping, cracking, spalling and ultimately leading to coating delamination [73, 80, 81].
Wear Estimation of Coated Tools Using XFEM / Level Set Function
2017, Procedia CIRPExperimental study of the effect of coating thickness and substrate roughness on tool wear during turning
2017, Tribology InternationalCitation Excerpt :In several studies on turning [9–17], which investigated the wear of coated cutting tools compared to that of uncoated ones, it was found that the wear rate of the latter is much higher. Some experimental studies [18–22] examined the effect of flank hard coating thickness on wear resistance in cutting tools. Different coatings were used deposited by two methods: physical vapor deposition (PVD) [18,21] and chemical vapor deposition (CVD) [19,20,22].
Finite element modelling of the thermo-mechanical behavior of coatings under extreme contact loading in dry machining
2011, Surface and Coatings TechnologyCitation Excerpt :In fact, coatings can act as a thermal barrier and also reduce friction [5]. In dry machining, using coated tools is necessary to improve the tool life as well as the quality of the machined surface [6–9]. For example, in automotive industries, the transition from wet to dry machining was studied by Lahres et al. [10].
