“…Silicon nitride cutting tools have captured application in cast iron machining which had previously been exclusively served by cemented carbide and alumina-based tools (Diniz & Ferrer, 2008;Grzesik, Rech, Zak, & Claudin, 2009;Reddy, Chakraborty, Mahajan, & Prasad, 1990;Souza, Nono, Ribeiro, Machado, & Silva, 2009). While capable of several ceramic applications, Si 3 N 4 is possibly the most ideal tool material for machining gray cast iron in turning, boring, and face milling operations.…”

“…In machining of cast iron using high speed, sulfur produces a manganese sulfide protective layer on the cutting edge. This protective layer can decrease the abrasive wear of the tool by acting as a lubricant and increase tool life [8,9]. Gastel et al [7] stated that this protective layer can also protect the tool from oxidation and diffusion at higher cutting temperatures.…”

Cutting Performance of Low Stress Thick TiAlN PVD Coatings during Machining of Compacted Graphite Cast Iron (CGI)

et al. 2018

Abstract:A new family of physical vapor deposited (PVD) coatings is presented in this paper. These coatings are deposited by a superfine cathode (SFC) using the arc method. They combine a smooth surface, high hardness, and low residual stresses. This allows the production of PVD coatings as thick as 15 µm. In some applications, in particular for machining of such hard to cut material as compacted graphite iron (CGI), such coatings have shown better tool life compared to the conventional PVD coatings that have a lower thickness in the range of up to 5 µm. Finite element modeling of the temperature/stress profiles was done for the SFC coatings to present the temperature/stress profiles during cutting. Comprehensive characterization of the coatings was performed using XRD, TEM, SEM/EDS studies, nano-hardness, nano-impact measurements, and residual stress measurements. Application of the coating with this set of characteristics reduces the intensity of buildup edge formation during turning of CGI, leading to longer tool life. Optimization of the TiAlN-based coatings composition (Ti/Al ratio), architecture (mono vs. multilayer), and thickness were performed. Application of the optimized coating resulted in a 40-60% improvement in the cutting tool life under finishing turning of CGI.

“…Their results showed that the dominant wear mechanism for aluminum oxide-based ceramics was abrasion, while for silicon nitride-based ceramics the basic mechanism was diffusion. This comparison was made in terms of tool life and workpiece surface roughness and to understand the wear mechanism of silicon nitride-based ceramic tools and coated carbide tools in turning of ADI (Diniz et. al., 2008 andGrzesik et.…”

The aim of this research is to compare TiN (PVD) coated Al 2 O 3 +Ti[C,N] mixed alumina-based (KY4400) ceramic and CVD coated carbide TiC+AI 2 O 3 +TiN (ISO P25) cutting tools in turning austempered ductile irons. Ductile cast iron samples were austenitized at 927°C and subsequently austempered for 1 hour at 400°C. The hardness of the workpiece material was measured and found to be 43.5 HRC. In the present work a series of tests were conducted in order to evaluate the tool performances by adopting tool life. In all experiments cutting forces, flank wear and surface roughness values were measured throughout the tool life. No cutting fluid was used during the turning operations. Study of the tool life and failure modes shows that tool life was determined by the flank wear and surface roughness generated on the workpiece. The main conclusion is that tool life of ceramic insert was longer than the coated carbide insert although much higher cutting speeds were used.
