Speech Title: Ultra-High Precision Machining of Optical Mould Inserts
Abstract: Metal cutting techniques that result in surface roughness in the ranges of few nanometres and form accuracy in the sub-micron region are categorised as ultra-high precision machining (UHPM). In this technology, diamond inserts are used to shape components from various non-ferrous materials by lathe operation. These components are usually optical objects such as flats, convex and concave lenses made from aluminium, copper alloys, silicon, germanium, etc. Diamond turning can also be used to produce mould inserts for plastic optics injections. Optical injection moulds are usually made from high strength aluminium such as AA 6061 and beryllium copper alloys. These materials are easily machined by diamond tools. However, for high requirements mould inserts used for glass moulding, the mould inserts must be made from ultra-hard materials such as tungsten and silicon carbides. UHPM of these materials can be achieved using ultra-high precision grinding spindles. This presentation will highlight the capabilities of precision engineering when making optics and mould insert manufacturing. Optical components, including freeform, with form accuracy of about 0.1 um and surface roughness of 1 nm can be produced with diamond machining. Currently, we are busy investigating the process of diamond turning when machining a special grade of aluminium produced by rapid solidification and spin melting. This aluminium grade which enjoys elevated tensile strength (600 MPa) can be used as a mould material for injecting plastic optics.

Keynote Speaker II
Prof. Ramesh Kuppuswamy, University of Cape Town, South Africa
Speech Title: Use of Speed + Nano-meter to evolve Advanced Manufacturing solutions
Abstract: The on-going manufacturing challenges are largely vested on six main foci; productivity, complex profiles, micro-features, precision, emerging materials and environmental issues. This presentation would unveil how the speed and nano parameter was effectively used to address such manufacturing challenges. The derived Advanced Manufacturing solutions deals with how the machines and processes combined with science, information technology, microelectronics, and new organizational practices are integrated to facilitate improved manufacturing productivity and quality at reduced cost.The on-going manufacturing challenges are largely vested on six main foci; productivity, complex profiles, micro-features, precision, emerging materials and environmental issues.

Plenary Speaker I
Prof. Samir Mekid, King Fahd University of Petroleum and Minerals, Saudi Arabia
Speech Title: Value Analysis Value Engineering in Design Decision-Making and Impact on Manufacturing Cost Reduction with Industrial Examples
Abstract: Value Analysis Value Engineering (VAVE) becomes an integral part of the engineering design process embedded with customer real needs and related product functions cost. It is also moving little earlier in the design process to support technology development. Many in-market products are returning to office for VAVE analysis for the sake of manufacturing cost reduction including manufacturing time in mass production. Examples from industry will be discussed using VAVE analysis through better value estimation related to suitable manufacturing process while maintaining similar or better technical performance. A couple of technical design solutions are proposed and discussed with study cases.

Plenary Speaker II
Dr. Mardé Helbig, University of Pretoria, South Africa
Speech title: Dynamic multi-objective optimization: Applications, Issues and Future Directions
Abstract: Most optimization problems in real-life have more than one objective, with at least two objectives in conflict with one another and at least one objective that changes over time. These kinds of optimization problems are referred to as dynamic multi-objective optimization (DMOO) problems.
Most research in multi-objective optimization has been conducted on static problems and most research on dynamic problems has been conducted on single-objective optimization. The goal of a DMOO algorithm (DMOA) is to find an optimal set of solutions that is: as close as possible to the true set of solutions, and a diverse set of solutions. However, in addition to these goals a DMOA has to track the changing set of optimal solutions over time.
This keynote will introduce the participants to the field of DMOO by discussing: benchmark functions and performance measures that have been proposed and the issues related to each of these; algorithms that have been proposed to solve DMOO; challenges in the DMOO field that are not yet addressed, such as incorporating a decision maker’s preference in DMOO and visualizing the behaviour of DMOAs; real-world applications; and emerging research fields that provide interesting research opportunities.
Biography: Mardé Helbig is a senior lecturer at the University
of Pretoria, South Africa. She obtained her PhD at
the University of Pretoria, with her thesis
entitled: “Solving dynamic optimisation problems
using the vector evaluated particle swarm
optimisation algorithm”. Before joining the
university, she worked for 14 years at the Council
