“…In the study, α/β-SiAlON ceramic tool and its TiN reinforced match were manufactured in solid form with 12 mm diameter. The milling parameters were set as: cutting speed of 585 m/min, radial depth of cut of [4] 0.635 mm, axial depth of cut of 9.652 mm and feed rate of 0.18 mm/rev. Diffusion based wear emerged as the dominant wear mechanism.…”

“…For instance, 50% weight of a jet engine is Inconel 718 (IN-718), a Ni-Fe-Cr alloy [3]. Some of their unique qualities compose their exceptional mechanical properties such as; high strength, strong oxidation resistance, creep resistance, thermal stability, thermal fatigue properties and relative lightness [3,4]. An overview of some nickel based superalloy parts employed in a jet engine is displayed in Fig.…”

Nickel based superalloys offer high strength, corrosion resistance, thermal stability and superb thermal fatigue properties. However, they have been one of the most difficult materials to machine due to these properties. Although we are witnessing improved machining strategies with the developing machining, tooling and inspection technologies, machining of nickel based superalloys is still a challenging task due to in-process strains and post process part quality demands. Selecting optimum machining parameters for quality, productivity and profitability is of paramount importance. Many studies have been conducted on various aspects of machinability of nickel based superalloys including defining the optimum cutting parameters, to develop a better understanding of machining them. The recent studies suggest new findings, and discuss previously reported results, related to the concerns of superalloy machining. This review presents the influences of the most significant cutting parameters on various machinability characteristics with respect to the recent studies as well as the previous ones. The reviewed machinability characteristics may be listed as: tool wear, cutting forces and surface integrity.

“…The strongest properties that make the HRSA alloys, as the Inconel 718, so interesting are their excellent temperature strength and low thermal conductivity, but these properties, together with the severe work hardening tendency, are strong obstacles for the material machinability [1,2]. Therefore, HRSA materials ask for large cutting forces, and in addition, chips are easy to weld on the tool to form build up edge (BUE) [3,4]. As a result, cutting tool wears rapidly during machining.…”

Solid ceramic end mills for machining heat resistant super alloys (HRSA) have the potential to generate higher material removal rates, up to one order of magnitude, with respect to standard carbide tools. The machining operations in aerospace industry, where large removals are required to obtain tiny and slender parts like turbine blades, is a cost-intensive task that can benefit of the adoption of ceramic solid end mills. However, these tools show a quite limited tool life, especially when used with interrupted tool engagement strategies. Moreover, they might induce heat-related problems in the workpiece material surface integrity. This paper investigates the cutting and the tool wear during milling Inconel 718 with solid ø12 mm cutting end tool made by SiAlON. The wear mechanisms are studied together with their effects on process signals as cutting forces and power, measured via external and CNC integrated sensors. The carried experimental campaign allowed to find out that tool clogging and edge chipping were the primary cutting phenomena leading the tool wear. Cutting strategy (downmilling or upmilling) produced different results in terms of tool wear sensitivity and process outputs whereas upmilling configuration showed the best results in terms of cutting signals stability and surface integrity. At the same time, cutting speed was found to increase the cutting power more in upmilling than downmilling cutting. The analysis of the forces and power demonstrated that the typical tool wear mechanisms can be traced by signal monitoring due to their high impact on cutting processes. This fact shows the good potential of signal monitoring for a better tool life evaluation.

“…due to their thermodynamic instability in open atmosphere at high temperatures. Çelik et al [5] manufactured SiAlON based ceramic milling tools and tested them on high speed milling of superalloys. According to author's conclusions on test results, the cutting zone temperature exceeded to 1000°C, and oxidation and other diffusion processes became dominant at given test conditions.…”

SiAlON ceramics are successfully utilized in applications such as refractories used for metal melting and cutting tools for high speed machining of metals in which high temperature properties are important. As being one of the main indication of high temperature resistance for such applications, oxidation resistance of this materials are affected by microstructural features, type and amount of the rare-earth (RE) elements in α-SiAlON and grain boundary phase (GBP). In this study, oxidation behavior of α/β-SiAlON ceramics prepared by Er2O3 as well as Y2O3, which is one of the most widely used RE-oxide in commercial SiAlON compositions, was investigated comparatively. A slight difference was observed in oxidation resistance of Er2O3 and Y2O3 containing SiAlON ceramics due to their slightly different crystallinity of GBPs.
