Abstract

A CAD/CAM system known as the MODCON(1,2,3) has shown to be useful for producing machine parts such as rocker-lever, connecting-rods, etc. In spite of the usefulness of the MODCON system, it suffers the inherent disadvantage of a batch system and therefore does not interact with a MODCON user wishing to design a machine part. An interactive CAD/CAM system is now proposed which is conceptually similar to the MODCON system. The proposed system is implemented on a microprocessors based machine which includes a central processor, a numerical data processor and another processor for I/O. This low-cost/high-power machine enables a designer to interactively design a machine part to his satisfaction before a N.C. paper tape is produced for manufacturing purpose.
