ABSTRACT:
A method for detecting the cutting resistance of a workpiece to a bandsaw blade comprises the steps of: magnifying movement of the bandsaw blade by a magnifying device in a direction normal to a running direction of the bandsaw blade; detecting the movement of the bandsaw blade by a sensor in the direction normal to the running direction of the bandsaw blade; and adjusting a force exerted by a feed speed of the bandsaw blade during a cutting operation in immediate response to momentary changes in the cutting resistance of the workpiece to the bandsaw blade. An apparatus for carrying out the method is also disclosed.
