Ultrasonically assisted machining have led to several high TRL projects and products
The following projects are some examples where we lead research
ABSTRACT: Next generation histology to support stratified medicine diagnoses will need to increase the volume of samples processed, in order to perform screening exercises and to provide more intensive sampling for precise diagnoses. Laboratory automation is one key to this, but the art of reliably cutting the microscopically thin sections to view tissue samples under the microscope is the chief remaining barrier to this. Wear on cutting blades, sample damage, thickness problems, and the difficulty of handling the thin section, all require highly skilled operators. We plan to develop a novel ultrasonic cutting blade that will be capable of sectioning difficult materials easily, with controlled thickness, high precision and reduced blade wear, to support the drive to automation and a potential doubling of output to support highly intensive healthcare screening.

ABSTRACT: The UK and EU polymer processing industry continues to contract, with companies struggling to maintain market share against competition from low cost economies. Whilst energy cost reductions would be welcomed, cycle time and component thickness are key drivers of financial performance, with parts costed as a function of cycle time & machine hourly rate. The Ultramelt system will apply ultrasonic energy into the molten polymer just before it enters the cavity. This can yield as much as 60% temporary reduction in melt viscosity, enabling a significant reduction in melt temperature, saving both heating & cooling energy. The benefits of this are numerous. Melt temperatures could be maintained and the lower viscosity used to enable easier filling of existing parts or design of thinner-walled parts with corresponding reductions in cooling times. Alternatively, the melt temperature could be reduced significantly, while still being able to fill the same mould (due to the reduced viscosity). This technology could enable UK moulders to increase productivity and competitiveness, regain market share and capitalise on new business opportunities.
