ABSTRACT:
A feed control device is disclosed for controlling the feed speed of a tool relative to a workpiece to be machined. The device includes a load detector for generating an output signal in response to a load applied to the tool, a circuit responsive to the output signal generated by the load detector when the load is higher than a predetermined value for successively decreasing the feed speed until the load reaches the predetermined value, and a circuit responsive to the output signal generated by the load detector when the load is not more than the predetermined value for successively increasing the feed speed until the feed speed reaches a predetermined value.
