In this paper, a novel approach to the derivation of the tool-life distribution, when the tool useful life ends after a progressive wear process, is presented. It is based on the diffusion theory and exploits the Fokker-Planck equation. The Fokker-Planck coefficients are derived on the basis of the injuij theory assumptions. That is, tool-wear occurs by detachment of small particles from the tool working surfaces, which are assumed to be identical and time-independent. In addition, they are supposed to be small enough to consider the detachment process as continuous. The tool useful life ends when a specified total volume of material is thus removed. Tool-life distributions are derived in two situations: (i) both Fokker-Planck coefficients are time-dependent only and (ii) the diffusion coefficient is neglected and the drift is wear-dependent. Theoretical results are finally compared to experimental data concerning fiank wear land in continuous turning of a C40 carbon steel bar adopting a PIO type sintered carbide insert. The adherence to the experimental data of the tool-life distributions derived exploiting the Fokker-Planck equation is satisfactory. Moreover, the tool-life distribution obtained, when the diffusion coefficient is neglected and the drift is wear-dependent, is able to well-represent the wear behavior at intermediate and later times.

“…The BOX-Behnken Design is one of many that can minimize the number of results required for three factor experimental design. The levels of the cutting parameters have been selected by taking into account, according to the recommendations of Kyocera and literature survey [7]. The total 17 numbers of experiments were conducted under different cutting conditions and levels.…”

“…The HIP sintering method consists of placing the sintered Si 3 N 4 mass in a vacuum capsule and subjecting it to isostatic hot pressing. The simultaneous forming, sintering and compression take place; therefore, this method ensures relatively high bending strength and theoretical sinter density [11,12]. The injection moulded ceramic-metallic tool materials described in this chapter were manufactured in laboratory conditions at a quarter-technical scale.…”

This chapter presents a general characteristic of sintered tool materials, in particular sintered sialons, nitride ceramics, injection-moulded ceramic-metallic tool materials and cemented carbides and a general characteristic of their surface treatment technology and especially chemical vapour deposition (CVD) and physical vapour deposition (PVD) techniques. The results of our investigations in technology foresight methods concerning the development prospects of surface engineering of sintered tool materials are presented. In the next subsection, we discuss the outcomes of multifaceted research carried out with advanced materials engineering methods, including high-resolution transmission electron microscopy, into the structure and properties of multicomponent, graded and multilayer coatings on the investigated tool materials, including the newly developed injection moulded ceramic-metallic tool materials. Special attention was drawn to a one-dimensional structure of the studied PVD and CVD coatings and its impact on the properties of coatings.Keywords: sintered tool materials, foresight, surface engineering, PVD, CVD, coatings, nanostructure General characteristic of sintered tool materialsPowder metallurgy has found widespread applications in the manufacture of sintered tool materials.

Advanced sintered tool materials, due to the character of their work and complex wear mechanisms to which cutting tool edges are subjected, should satisfy numerous requirements including, in particular, high hardness, high impact strength, resistance to complex wear (adhesive, diffusive, abrasive and thermal wear) and to high temperatures, high compressive strength, stretching, flexing and bending, high fatigue and thermal strength, good conductivity and thermal capacity, cutting edge stability and good ductility [1][2][3][4][5][6][7][8]. A tool material with universal applications should merge the mentioned properties as far as possible and especially the highest wear resistance and hardness with high strength and good ductility accompanied by chemical inertness towards the workpiece. Despite the intensive development of materials engineering, a tool material has still not been produced which fulfil such requirements due to a fundamental contradiction between such properties as hardness and ductility.As mentioned in the Introduction section, in general-in the group of sintered tool materialsone can distinguish super hard sintered materials, mixe...
