Drive control of NC machine tools is based on linear interpolation. When curved surfaces are machined using linear interpolation, problems arise with the feedrate not reaching the command feedrate, machining accuracy and surface quality decreasing, etc. In order to solve such problems, a method for generating a toolpath based on the control characteristics of a machine tool is proposed. The effectiveness of the proposed method is confirmed through simulations and experiments. It is found that the proposed method can reduce the cutting time to approximately 50% of the time required when conventional CAM systems are used. The proposed method also improves surface quality.
