In recent years, the five-axis controlled machining using barrel tools has been attracting attention from the viewpoint of improving machining efficiency. In five -axis controlled machining, tool center point control is used to compensate the tool path. This process is effective for machining with ball end mills, where the distance between the tool center point, which is the command point, and the cutting point does not change, however it is not compatible with barrel tools, where the distance between the command point and the machining point changes depending on the tool posture. The objective of this study is to develop a tool path interpolation method for barrel tools. By changing the reference point in interpolation from the tool center point to the cutti ng point, the tool path is corrected to meet the accuracy set by the user. The effectiveness of the proposed method was verified by generating tool paths using the proposed method and conducting machining simulations and machining experiments.
