Abstract: The present invention aims to provide a work machine capable of performing tasks with high precision by preventing the deterioration of speed responsiveness of the hydraulic cylinder driving the working device, as well as preventing the hydraulic cylinder from surging or deviating. To achieve this, the controller calculates the correction value for the target operating pressure of the flow control valve to keep the meter-out pressure of the hydraulic cylinder, measured while driving the hydraulic cylinder to perform a predetermined operation on the working device, within a range from a predetermined first lower limit to a predetermined first upper limit, and corrects the target operating pressure according to the correction value.

Abstract: A method for shearing a plurality of layered amorphous alloy foils 28 includes blanking the plurality of amorphous alloy foils 28 with a shear tool having a punch 12 and a die 14 through one descending of the punch 12. The punch 12 has a first edge E1 formed on a tip surface 12a of the punch 12 and a second edge E2 formed on a side peripheral surface 12b of the punch 12. A horizontal distance l between the first edge E1 and the side peripheral surface 12b and a vertical distance h between the second edge E2 and the tip surface 12a are each set in a range of 0.010 mm to 0.050 mm. A vertical distance h is set to 52% or less of the thickness of each amorphous alloy foil 28.
