This study deals with developing a curved hole machining method. Mechanical engineers have taken it for granted that drilling is to machine a straight hole. Therefore, straight holes have been used even in unsuitable cases. The typical case is the polygonal-line-shaped pipe line consisting of a series of straight holes machined by drilling, for example, the pipe lines used in pneumatic or hydraulic equipments, and the water channels built in molds. The fabrication of the pipe lines requires pipe plugs and extra holes inevitably. In addition, the pressure loss is taken place at the sharp bending point. To solve these problems, it is desired that the curved hole machining method is established and arbitrary shape and arrangement of the pipe lines can be made. Hence, we developed a new mechanism to machine curved holes. From experimental results, it is found that the mechanism is capable of machining 3-dimensional curved holes, difficult to create in a conventional manner.
