The operative range of existing sensors is very limited with respect to withstanding harsh environments (high temperature or pressure, severe strains, etc.). Additionally, available sensors are limited in spatial and temporal resolution due to their large size. This paper reports on design, fabrication and characterisation of embedded sensors for harsh

Abstract The present paper investigates a transformation induced fracture mechanism for the cutting of Polycrystalline Cubic Boron Nitride (PCBN) sample by a hybrid CO2 laser/waterjet (CO2-LWJ) manufacturing process. In CO2-LWJ machining, a laser was used for local heating followed by waterjet quenching leading to fracture propagation along the ...

A novel cost-effective pressureless sintering method has been developed to prepare polycrystalline cubic boron nitride (PcBN) compacts. The effect of feldspar as sintering aids was analyzed in this paper. Various amounts of feldspar from 5 to 15 wt% were added to cBN powders, and the pressureless sintering was conducted at temperatures ranging from 900°

Abstract The performance of polycrystalline cubic boron nitride (PCBN) was studied to investigate surface roughness analysis at various machining parameters. The PCBN tools were used in tool steel AISI D2 steel with hardness of 64 HRC. Machining test was performed with dry cutting condition at different cutting speed, feed and depth of cut.

3 min −1 . Carbide inserts were also tested under the same cutting conditions. The tests were carried out in the dry condition. Three different hardened steels were cut and the wear mechanism was investigated using a scanning electronic microscope (SEM). The minimal wear mechanism found was a combination of adhesion and abrasion.

The samples of Polycrystalline cubic boron nitride (PcBN) cutting tool were machined by adjusting the main parameters of electrical discharge machining (EDM). After the machining, the phases were analyzed by X-ray diffraction analyzer and the surface layer microstructure was observed by scanning electronic microscope.
