Abstract
Measuring cutting force is effective in monitoring machining processes, but requires that a force sensor be installed on the tool table. The parallel disturbance observer we propose in table control using velocity response and current reference realizes both robust control and cutting force estimation without additional sensors. Performance of this method was evaluated through simulation and experiments.
