ABSTRACT:
A force control method for a bar feeder supporting a workpiece in a lathe, including seizing the workpiece by a Z-axis spindle of the lathe and the bar feeder, performing position control by the Z-axis spindle of the lathe, and performing force control by the bar feeder to apply a constant torque to the workpiece during the force control of the bar feeder supporting the workpiece in the lathe. This control of the bar feeder does not require the Z-axis spindle of the lathe and the bar feeder to be synchronized for the position control in the Z-axis direction, and prevents the workpiece from being deflected.
