“…Machining of ultra-high-strength steels is achieved by using Al 2 O 3 based cemented materials and coated cemented carbide. Wang et al [32] studied micro-structure and mechanical properties of proposed cutting tool material Al 2 O 3 /TiC/TiN and the machining conditions on ultra-high steel and the wear mechanism in comparison with Al 2 O 3 /TiC ceramic tools. The best result is with a sintering temperature of 1650°C, holding time 15 min and sintering pressure 35 MPa.…”

For mechanical machining the quality of cutting-tool materials is one of the most significant issues that need to be addressed. Enhancement of cutting tool performance may be achieved through the use of modern composition ceramic cutting tools This may be enabled through surface treatment, and also hot pressing and spark plasma sintering – the two main processes used for manufacturing such tools. In this article the advantages and disadvantages of the technologies and processes involved are analyzed and compared to identify the most appropriate methods for creating ceramic cutting-tools. In parallel the latest improvements in ceramic cutting-tool materials are reviewed. The paper shows that the choice of ceramic cutting tools is a quite complex process with a number of important factors to be taken into account.

“…The toughening mechanisms by TiN are mainly related to the cracks; for example, the crack deflections and crack pinning mechanism were revealed by Li et al [8], the crack tilting and twisting mechanism was revealed by Shen et al [9], and the crack propagating along the grain boundary was observed by Qiao et al [10]. Recent work showed that when adding both TiN and TiC particles into alumina ceramics, the composite had excellent hardness and fracture [11][12][13], and the cutting performance was better than LT55.…”

Al 2 O 3 -TiN-TiC ceramic materials with different Ni content were fabricated by hot-pressing technique. Mechanical properties such as flexural strength, Vickers hardness and fracture toughness were obtained by three-point-bending test and Vickers indentation method. The microstructures of the sintered body were observed by scanning electron microscopy. The effects of Ni content on the microstructures and the mechanical properties of Al 2 O 3 -TiN-TiC ceramic materials were investigated. The results indicated that the addition of Ni could change the topography of the microstructures which displayed various core-shell structures. Moreover, the fracture mode changed with the increment of Ni content. When the addition of Ni was 3 vol%, the flexural strength and fracture toughness were the greatest and the improvement could be explained by the unique microstructures of sintered bodies.

“…Ceramic cutting tools have been widely used as the preferred cutting tool [1] for the past century and continue to be used for machining in hard and di cult to cut materials such as alloy steel [2]. The reasons are because of their outstanding properties, such as wear resistance, shock resistance, and high hot hardness [3][4][5][6][7][8][9]. Moreover, alumina (Al 2 O 3 ) based cutting tools are the most frequently used ceramics in machining hard materials [7][8] and have been a desirable choice to improve the quality of products and minimise the costs of manufacturing and production time [10].…”

The zirconia toughened alumina enhanced with titania and chromia (ZTA-TiO2-Cr2O3) ceramic cutting tool is a new cutting tool that possesses good hardness and fracture toughness. However, the performance of the ZTA-TiO2-Cr2O3 cutting tool continues to remain unknown and therefore requires further study. In this research, the wearing of the ZTA-TiO2-Cr2O3 cutting tool and the surface roughness of the machined surface of stainless steel 316L was investigated. The experiments were conducted where the cutting speeds range between 314 to 455 m/min, a feed rate from 0.1 to 0.15 mm/rev, and a depth of cut of 0.2 mm. A CNC lathe machine was utilised to conduct the turning operation for the experiment. Additionally, analysis of the flank wear and crater wear was undertaken using an optical microscope, while the chipping area was observed via scanning electron microscopy (SEM). The surface roughness of the machined surface was measured via portable surface roughness. The lowest value of flank wear, crater wear and surface roughness obtained are 0.044 mm, 0.45 mm2, and 0.50 µm, respectively at the highest cutting speed of 455 m/min and the highest feed rate of 0.15 mm/rev. The chipping area became smaller with the increase of feed rate from 0.10 to 0.15 mm/rev and larger when the feed rate decrease. This was due to the reduced vibrations at the higher spindle speed resulting in a more stable cutting operation, thereby reducing the value of tool wear, surface roughness, and the chipping area.
