Feed-system autotuning of a CNC machining center: Rapid system identification and fine gain tuning based on optimal search

We report an autotuning technique for feed systems of a CNC machine tool using a least-square parametric system identification, a frequency-domain design method, and a fine-tuning method based on an optimal search algorithm. The feed system of a movable-column-type vertical machining center has a la...
