LOW COST GEOMETRIC MODELLING SYSTEM FOR CAM.

Abstract

A geometric modelling system is implemented on a low cost, medium resolution, colour graphics workstation. When compared with other CAD/CAM systems for the design and manufacture of engineering components, the proposed system is more oriented towards the manufacturing of 3-dimensional geometric model using Numerical Control machine. The colour graphics capability allows a designer to interactively create simple 3-dimensional geometric shapes as the building blocks for complex 3-dimensional engineering component. By 'shape operation' on the building blocks interactively with feed back from the graphical screen, the final design as appeared on the graphical screen can then be manufactured by Numerical Control machine subject to designer specified manufacturing parameters such as Numerical Control machine cutter size and the degree of surface finishing.
