Abstract:

Ti6Al4V is one kind of difficult-to-machine aeronautical materials, which is generally machined by coated cemented carbide tools. A three-dimensional face milling model is developed in this paper with finite element analysis software AdvantEdge to analyze influences of tool materials on tool temperatures, cutting forces and tool stresses. The simulation results have shown that PCBN tools are the most appropriate for machining titanium alloy when it is machined with heavier cutting parameters. Cemented carbide-K tools and PCD tools are suitable for finish machining titanium alloy. The PCD tools

Abstract:

Carbide cutting tools are used for machining of machine parts made of complex alloyed materials. Application of protective composite nanostructured coatings on carbide cutting tools allows increasing the service life of cutting tools several times. The coating on their base protects the cobalt binding of carbide alloys. The low thermal conductivity of the composite nanostructured titanium carbide coating means that the heat generated when cutting workpieces is mostly transferred to the chips so that the tool does not become overheated. This is important when machining difficult alloyed, hard-t

Thispaper presents the results of the studies of the combined influence of properties of carbide substrate and composite coatings on tool wear resistance in machining of chromium-based heat-resistant alloys.

For carbides with relatively low strength and crack resistance, the efficiency of coatings appeared to be unsatisfactory because of brittle fracture of the substrate and thus intensive failure of coating.

Abstract:

As-cast high-speed steels heat-treated have completely much lower impact toughness than that of the steels of a similar chemical composition but undergone hot working – rolling or forging. That is attributed to the influence of eutectic carbides, which especially being coarse, provide easily brittle intergrain fracture sites under low stress intensity factor levels. This is especially real for cast cutting tools. In order to exhibit good all-round performance the impact toughness enhancement of as-cast high-speed steels is obligatorily needed. In this connection it is expedient to turn from hi

Abstract:

According to the characteristics of NM360, a contrast experiment for drilling performance in YG8 cemented carbide twist drill, high-speed steel twist drill and factories used in coating the ordinary high-speed steel twist drill has been done. Using microscope to observe tool wear, we found that the flank wear and chisel edge wear are the main wear of the drill. The carbide tools has a better ability of resistance to plastic deformation, abrasive wear and adhesive wear than high-speed steel cutting tools. The coating tools are better to resist abrasive wear and adhesive wear than uncoated tools

Abstract:

TA15 (Ti-6.5Al-2Zr-1Mo-1V) is a close alpha titanium alloy strengthened by solid solution with Al and other component. A series of experiments were carried out on normal and high speed milling of TA15. The recommended tools for many years had been the uncoated tungsten carbide grade K. In this work, the tool life of coated carbide tools used in high speed milling of forging and cast titanium alloy was studied. Additionally, the wear mechanism of cutting tools was also discussed. Finally, surface integrity, including surface roughness, metallograph and work hardening, were examined and analyzed

Abstract:

Gear Hobbing is a complex gear manufacturing method, possessing great industrial significance. The convoluted geometry of the cutting tools brings on modeling problems and is the main reason for the almost exclusive application of HSS as cutting material. However, despite its complicated kinematics, gear hobbing is sufficiently described by well-established software tools, which were presented in the first part of the present paper. Experimental investigations exhibited the cutting performance of cemented carbide cutting teeth, which were expected to be potential alternatives for massive hob p

Nickel-based superalloys are widely used in the aeronautical industry, especially in components requiring excellent corrosion resistance, enhanced thermal fatigue properties, and thermal stability. Haynes 282 is a nickel-based superalloy that was developed to improve the low weldability, formability, and creep strength of other γ’-strengthened Ni superalloys. Despite the industrial interest in Haynes 282, there is a lack of research that is focused on this alloy. Moreover, it is difficult to find studies dealing with the machinability of Haynes 282.

Abstract:

We have designed tungsten carbide tools with a new binder, which makes them suitable for advanced diamond tool coatings. The new tool substrates, made of tungsten carbide and nickel aluminide as binder phase, are produced by sintering and hot isostatic pressing, and also by combustion synthesis. The high temperature strength of nickel aluminide is key to superior tool performance at elevated temperatures. More importantly, nickel aluminides reduce the formation of graphite and promote diamond growth during chemical vapor deposition. Diamond films are deposited on the new tool substrates to inv

This study reports an experimental investigation about the wear behavior of TiN and TiCN coated carbide tools during the face milling of pearlitic and ferritic ductile cast iron. Pearlitic ductile cast iron caused the highest cutting forces and flank wear in both TiN and TiCN coated tools. Due to its protective effect, the TiCN coated carbide tool outperformed the TiN coated carbide tool regarding flank wear. The main issue when face milling ferritic ductile cast iron with TiN coated tools was notching wear. The principal reason for notch wear was pointed as adhesive wear caused for the high t
