Abstract
This research assessed, among others, the current status and the impact of Computer-Aided Design (CAD) and Computer-Aided Manufacturing (CAM) applications in the Nigerian industrial and technological sector. Two prominent cities Lagos and Ibadan were selected as centers of case studies to establish the level of the applications. Data was collected from industries within the 2 cities in the areas of manufacturing, design, production, construction and consultancy service units during a year long study. From the survey, 56% of companies visited in Lagos metropolis apply Computer-Aided Engineering (CAE) activities in their operations. Also 60% of the companies considered in Ibadan metropolis apply CAE, of which 75% are into CAD, 12.5% are applying CAM whereas 12.5% are utilizing Computer Numerically Controlled (CNC) machines. Conclusively, the commonest CAD techniques employed by the industries surveyed are Auto CAD and Archi CAD representing 55.6% and 33.3% of the total packages being used in the visited companies respectively.
Highlights
The application of Computer-Aided Design (CAD)/ design activity, allowing a full integration of design, Computer-Aided Manufacturing (CAM) systems and their analysis and manufacture in a single Computer-Aided Engineering (CAE) system
The problems of the were drafted and given to engineers, technologies, manufacturing sector have often been attributed to technicians and administrative managers in 28 applicable inadequate infrastructure and absence of a sound companies to assess their level of CAE education and technological base in these developing nations
CAD/CAM applications group and individually. This allowed free of CAD/CAM technology without taking in some developed nations expressions of problems and courses or training on CAE into in recent years expectations of the industries from the consideration: but brings out the capabilities of CAD/CAM which the researcher/engineer can utilize to increase creativity and productivity
Summary
The application of Computer-Aided Design (CAD)/ design activity, allowing a full integration of design, Computer-Aided Manufacturing (CAM) systems and their analysis and manufacture in a single CAE system. Engineering (CAE) systems in developed countries in the Methodology of study recent years due to the benefits derived from such Administration of questionnaire: Data collection using methods. The problems of the were drafted and given to engineers, technologies, manufacturing sector have often been attributed to technicians and administrative managers in 28 applicable inadequate infrastructure and absence of a sound companies to assess their level of CAE education and technological base in these developing nations. This allowed free of CAD/CAM technology without taking in some developed nations expressions of problems and courses or training on CAE into in recent years expectations of the industries from the consideration: but brings out the capabilities of CAD/CAM which the researcher/engineer can utilize to increase creativity and productivity.
