The performance of ultra-hard cutting tool materials in maching aerospace alloy TA48
… carbides, and 760 and 900 °C for PCD and CBN tools respectively. Furthermore, the technique has been used to study the integrity of the bulk; tool material, and/or individual coatings on their substrates, when welded junctions formed between the tool and workpiece are separated. With regard to …

The application of time encoded signals to automated machine condition classification using neural networks
This thesis considers the classification of physical states in a simplified gearbox using acoustical data and simple time domain signal shape characterisation techniques allied to a basic feedforward multi-layer perceptron neural network. A novel extension to the signal coding scheme (TES), …

The development of stage machinery in the nineteenth century British theatre : a study of physical and documentary evidence
Thc devolopment of scene changing machinery in Great Britain is perhaps one of the few disciplines in the field of mechanical engineering which have virtually never relied upon new discoveries in technology for their advancement. Instead it has always lagged behind, perhaps modifying, certainly …

The design and control of mechanical switched mode drives
This thesis is concerned with the design, control and performance evaluation of a novel design for mechanical drives. This drive operates in a pulsed manner where energy is extracted from the input, stored and then released to the output. A spring acts as the energy store and brakes and clutches …

The application of the soft impression technique to evaluate flow stress, creep and frictional deformation of polycrystalline diamond and cubic boron nitride
Metal shaping processes are clear examples of engineering applications where a hard material is worn by a softer one - i.e. the tool and workpiece respectively. The soft impressor technique, introduced by Brookes and Green (1973), has proved valuable in measuring the relevant mechanical properties …
