Abstract

In recent years, complicated shapes have been required to be machined at a shorter time. Machine tools have become highly accurate and had multifunction as well as the development of CAD/CAM systems. However, there exist a lot of things difficult or impossible to create even by multi-axis control CNC machine tools. Most of them are made by skilled persons of ingenuity and device. In the future, it is predicted that consumer needs are getting more various and that consumers require individual goods matching for their feeling. The study presents the first trial of creating an artistic workpiece by use of a multi-tasking machine tool. Such a machining technology may be called "Dexterous Machining". As an example, a chain-shaped workpieces are selected, which cannot usually be machined in the conventional manner. Thus, a special type CAM system is developed, taking account of the interference between a cutting tool and a workpiece, and by use of the second main spindle. As a result, it is found that the developed CAM system has the potential of realizing Dexterous Machining.
