Feature-based computer-aided process-planning system (in Polish) Opracowanie systemu wspomagającego planowanie procesów obróbkowych metodą obiektów elementarnych

The aim of the monograph was to establish a framework for automatic process-planning system, based on recognized features and using an expert system. The system will be designed for the planning of machining prismatic parts on the basis of 3D CAD data. In the first stage of the project, the analysis of the input data from a CAD system is carried out. Then the algorithms of recognising functional construction and technological features from solid 3D CAD models are developed. The input models are stored in neutral data formants: IGES or STEP. In the next stage, recognized features are clssified. An expert system is used to plan manufacturing processes. The expert system includes the following modules: inferences, technological knowledge database, machine tool database and tool database. The final module of the designed CAPP system generates output data, i.e., CL data files necessary to create programs for NC machine tools.
