Automatic Generation of NC Commands Based on a Machining Product Model

Abstract

For generating NC machining commands automatically, it is important to handle computer models such as geometrical shape data and product data including engineering specifications for the mechanical part to be manufactured.Based on this concept, we proposed a product model especially designed for machining applications. We developed a system which generates NC commands for rough machining automatically by using product model. Through machining experiments with these generated NC commands, we confirmed the effectiveness of our product model.
