This paper makes it possible to predict the output motion of a parallel mechanism and proposes a method for generating a tool path of a machine tool consisting of the parallel mechanism. As a numerically controlled machine tool generally processes a work by interpolating an ideal shape with linear lines, a deviation between a path of tool and the ideal shape can be estimated easily. However, an input-output relation of the parallel mechanism is nonlinear, and accordingly an output pose of the parallel mechanism can be hardly determined by the direct kinematics. A prediction of the deviation of the parallel mechanism machine tool is therefore extremely difficult, so that a generation of its tool path that ensures a given allowance is not easy. Thus the present study proposes a simple method to predict the tool path of the parallel mechanism by approximating its motion with a spiral path. By using a prediction result, the study determines an efficiently optimal cutter location data to realize the tool path that ensures a required deviation.
