The Architecture of Intelligent System for CNC Machine Tool Programming

The goal of the paper is to present the architecture of CNC machine tool programming system based on the meta-knowledge and recognition of workpiece intermediate states. Meta-knowledge represented as hierarchical decision nets has the control role over manufacturing knowledge stored in the form of production rules. This is a Computer Aided Process Planning System (CAPP) with the functionality limited to the CNC machining. Additionally, both the manufacturing knowledge as well as feature recognition and processing algorithms were developed specially for the CNC machining.
