In recent years, manufacturing industries are facing severe competition to achieve products with high quality and low price. It is important to establish a new approach of creating value-added products like objects of craftwork or applied arts, different from traditional way of achieving products with high quality and low price. Manufacturing such value-added products generally needs skill and experience of experts. Thus, the objective of the study is to develop a CAM system for a multi-tasking machine in order to create value-added products, while converting implicit knowledge of experts into a formal knowledge. This kind of manufacturing way is named “Dexterous machining". The study deals with the CAM system to create a complicated shape consisting of bended columns as "Dexterous machining”. The CAM system developed in the study can generate the tool path for rough cutting and finishing cutting in consideration of interference avoidance. The effectiveness of the CAM system is confirmed by demonstrating two kinds of bended columns by use of a multi-tasking machine.
