Cost benefit analysis of computer aided engineering implementation in bespoke engineering business.

Advanced Computer Aided Engineering (CAE) is a field that expands continuously, concurrently with technology growth. Exceptional benefits are available by implementing the techniques in the business activities. Design capability is the biggest asset to any engineering organisation and it is more important to maintain and update constantly. It is evident that during 1990 to 2010, the pace of technology growth reached its peak value and contributes to rapidly improving business growth patterns. Despite many limitations, it is interesting to see a bespoke engineering firm improve in performance and their benefits coming from the implementation of these advanced CAE techniques.The thesis describes a two year partnership project between Sheffield Hallam University and Joseph Rhodes Limited, Wakefield in which 3-Dimensional Computer Aided Design (CAD) modelling, dynamic simulation, Finite Element Analysis (FEA) and 3D CAD animation were applied to four company machines i.e. rubber die press, knuckle joint press, HME Coining press and clay extrusion machine to enhance both pre- and post order processes. Direct cost savings of £114,000 were achieved due to savings in designer's time and materials for major components as a consequence of improved stress analysis.The project transformed the company's traditional method of 2D drawing methods to 3D methods with massive improvement in design standards. It also helps the designers to develop innovative design ideas with greater confidence and reliability. In addition to direct savings, improvements in tendering and quotation documentation due to 3D CAD were instrumental in increasing the overall company turnover by 300% from £7 million in 2007 to £21 million in 2010 with net profit averaged about £3 million. On conclusion of the project 6 designers were regularly using advanced CAE tools and techniques.
