Adaptive Interpolation of Tool Posture Vector in Five-Axis Flank Milling

Abstract:

Five-axis flank milling is an important machining technique, especially in machining of complex parts. Tool posture vector can change easily using two axes of rotation to achieve optimum cutting conditions. However, the tool posture vector may change beyond the interpolation plane. This will result in overcut or undercut. In this paper, an adaptive interpolation algorithm of tool posture vector is proposed. In the proposed algorithm, the commanded feedrate for linear axis is kept constant for most time and adaptively adjusted to confine the chord error within a specified tolerance range during the interpolation process. The tool posture vector changes in the interpolation plane with a constant rotation degree. Simulation results from example are provided to verify the feasibility and advantages of the proposed scheme.
