Abstract

In recent multiaxis-controlled machine tools, a new planning method to keep continuous motion on rotational axes and tool setting with short shank length from tool holder end is required to realize both high productivity and fine surface. This paper propose a new planning method consisting of a temporary search of new tool posture based on estimation of the required shank length and the gradual optimization process of motion on rotational axes. The proposed method repeats the following three planning steps: the estimation of interference between the cutting tool and workpiece, the search for a new tool posture to avoid interference and the re-planning of tool posture changes to prevent rapid motion on rotational axes. By repeating these steps many times, continuous change can be gradually realized in rotational axes without interference.
