The advanced machining of components used in miniature unmanned aircraft vehicles is the focus of this study. The finite element method (FEM) is used to predict forces and temperatures using cutting tool inserts with a thin nanostructured film of hig

Diamond-coated cutting tools are known to machine complex materials with many benefits associated with the generation of lower temperatures between contact surfaces. However, the complexity associated with machining exotic materials at the micro-scal

The machining of axle hub flange housings manufactured using G10530 steel is described in this paper. The machining of axle hub flange housings can lead to the entanglement of chips around workpiece holding fixtures, which leads to a loss of producti

The processing of polymer-bonded explosives is not widely reported in the literature, especially the machining of explosive surrogates in the combined planing and grinding operation known as plano-grinding. The process of machining long pieces of an

The studies described in this paper focus on the wear behavior of duplex grade abrasive segments grinding AISI 1020 and A36 steels on a vertical spindle surface grinding machine (VSSG). The study focuses on the behavior of the abrasive segment and ho
Gold is expected to form a relatively low barrier on hydrogenated thin film diamond, and this metallisation has therefore been widely used as the ‘ohmic’ contact for electronic devices fabricated using this material. However, gold contacts are no

Hydrogenated polycrystalline CVD diamond films support a number of defect states within the range 0.03-1.0 eV, as determined by charge-based deep level transient spectroscopy (Q-DLTS). The observation of a 30-meV state is direct evidence for such a s

A secondary glow region is commonly observed between the main plasma ball and the substrate during biased enhanced nucleation (BEN) of diamond films grown using the process of microwave plasma-enhanced chemical vapour deposition. Under conditions of

Considerable interest exists in fabrication of electronic devices from thin film polycrystalline diamond. To date, doping this material to achieve good free carrier concentrations and mobilities at room temperature has proved difficult. In this lette

Low temperature Hall effect measurements made on diamond films subjected to a hydrogenation process, such that the near surface region becomes p-type without the addition of conventional dopant atoms, are reported. The carrier concentration within th
