Abstract:
A process for controlling a motorized feed drive for a moveable workpiece table of a machine tool having a cutting element, the workpiece table being moved past the cutting element in a direction of feed by an operator of the machine tool applying a manual force to the workpiece table, comprising:sensing the manual force exerted by the operator of the machine tool on the workpiece table in the direction of feed; converting the sensed manual force to a corresponding electric value; deriving a set value for a feed rate of the workpiece table from the electric value; deriving a control signal for the motorized feed drive from the set value; and inputting the control signal to the feed drive to control a drive force, supplemental to the manual force, applied by the feed drive to the workpiece table.
