The model proposed describes the relative motions between the tools and the workpieces. The relations between the shape generation process of machine tools and the geometries of the product surfaces were analyzed based on the model.2. Relations Between Shape Generation Process and Basic Structures of Machine ToolsThe relations between the shape generation process and the basic structures of machine tools were analyzed aiming at establishing a design criteria needed for designing suitable structures of machine tools. In particular, shapes and functions of main components of machine tools were clarified.3. Development of an Analysis System of Machining AccuracyAn analysis system was developed to estimate the effect of the kinematic errors of the machine tools on the geometric errors of the product surfaces to be machined. The system can calculate the geometric errors on the product surfaces from the kinematic errors of the machine tools based on the matheniatical model of the shape generation process.4. Analysis of Autonomous Functions of machine ToolsAutonomous functions of machiyie tools were discussed from the viewpoint of the autonomous distributed manufacturing systems. An object oriented model was proposed to represent the distributed decision making functions of machine tools, and an autonomous distributed scheduling system was developed based on the object oriented model proposed.
