“…4d, e. Moreover, thermal cracks propagated along the rake face and coating flaking occurred where the crack propagated. Similar failure modes have been previously reported when machining nickelbased superalloys using ceramic tools [27,28]. The thermal crack was thought to be an important factor that contributed to Fig.…”

Coated carbide tools are widely used in machining titanium alloys due to their excellent wear resistance, high strength, and hardness even at elevated temperature. The paper gives a special attention to the failure mechanisms of coated carbide cutting tools during high-speed intermittent cutting process. The effects of serrated chip formation on the instantaneous cutting forces, transient temperature, and thermal stress distributions on the cutting tool were investigated based on finite element method (FEM). The results show that the cutting tools undergo combined thermomechanical and high/low cycle fatigue loading during intermittent cutting process. Micro-crack propagation and coating delamination were observed on the cutting edge and rake face. Flank wear and brittle fractures on the cutting edge caused by crack propagation were identified as the main failure mode of coated carbide tools in intermittent cutting process. Intense tensile thermal stress on the cutting tool edge was found to be produced by differential cooling rates in the idle periods. The rapid alteration of stresses was believed to be the direct cause of crack propagation on the cutting edge.

“…It is well known that the process of tool ceramics diamond grinding is accompanied by high contact temperatures and power loads that result in the formation of the surface defect layer containing a significant amount of micro-cracks and pores as well as fields of tensile stresses [1,5,6]. This has a very negative impact on the operational functionality of ceramic inserts and along with low mechanical strength and it is the main reason for their brittle fracture during the cutting.…”

-Ceramic cutting tools have a large potential by high speed processing of difficult-to-cut steels and alloys, however due to its fragility they don't assure the required reliability level of cutting process. For improving the operational characteristics of the ceramic cutting tool combined treatment can be used namely the preliminary planetary grinding of the insert surface and the following deposition of the vacuumplasma coatings (TiCr)N, (ZrCrHf)N and other.

“…Therefore, cemented carbide tools are unable to meet the requirements of high material removal rate and good surface quality. Ceramic tools are characterized by high hardness, great heat resistance, good wear resistance, and chemical stability [11][12][13][14][15]. They are one of the most important ideal choices in machining ultra-high-strength steels.…”

An Al 2 O 3 -based micro-nano-composite ceramic tool material reinforced with TiN micro-particles and TiC nanoparticles was fabricated by using the hot-pressing technique. The wear behavior of the Al 2 O 3 /TiC/TiN micro-nanocomposite ceramic cutting tool (AT10N20) in high-speed turning of ultra-high-strength steel 300 M was investigated by comparison with the commercial Al 2 O 3 /TiC composite ceramic tool CC650. Worn and fractured surfaces of ceramic cutting tools were observed and analyzed via the scanning electron microscopy (SEM) combined with the energydispersive X-ray spectroscopy (EDS). The results showed that the main wear modes of AT10N20 and CC650 were flank wear and rake wear. The crater on the rake face of AT10N20 initially occurred at cutting speed of 400 m/min, while it occurred at cutting speed of 200 m/min for CC650. In addition, the rake wear and flank wear became more severe when the cutting speed attained 400 m/min. The cutting speeds higher than 400 m/min were unfavorable for turning of ultra-highstrength steel 300 M. Wear mechanisms of AT10N20 and CC650 in high-speed turning of the ultra-high-strength steel were abrasion and adhesion.
