  • Title
    • Process Material Interaction during Micromachining of Biomedical Polymer Materials
  • Summary
    • This work focused on the characterisation of process material interaction during the micromachining of a biomedical grade polymer which is used to manufacture intraocular lens (IOLs) by the partnering company, Alcon. The machining characteristics of polymers depend primarily on their mechanical, thermal, and rheological properties. High material elasticity and thermal expansions may make efficient material removal and precision machining a challenge. Often, low thermal conductivities and softening temperatures further hamper these efforts. Many properties are also highly temperature and strain-rate sensitive which can cause unwanted changes in material behaviour in the cutting zone during machining.

  • Title
    • Fundamental Investigation into the Machining of Cobalt Chrome
  • Summary
    • Cobalt Chrome alloys are used extensively within the biomedical industry during the manufacturing of orthopaedic implants due to their desirable mechanical properties of fatigue resistance, tensile strength, corrosion resistance and biocompatibility. However, these alloys are difficult to machine due to their strain hardening capabilities. The goal of this research is to develop a fundamental understanding of the cutting mechanics of Cobalt Chrome, specifically for biomedical applications through the development of a Finite Element Model and a statistical machining campaign.

  • Title
    • Design of a Low Powered Emergency Exit Sign
  • Summary
    • This research was focused on the design and manufacture of a Low Powered Emergency Exit Sign that consumes 80% less power than standard signs. This was achieved through the design of a novel light guide and diffuser films using low powered LEDs. The product was brought from concept to prototype and met all luminance, lux and contrast measurements to ISO Standards.

  • Title
    • Design of a Water Harvesting System
  • Summary
    • This research was focused on the design of a Water Harvesting System for domestic households. The system was designed to store and deliver rainwater for toilet flushing and garden irrigation. When the system store is low, it is supplemented by water from main.
