A computer-implemented method is provided for shaping an edge of a part to be cut from a workpiece using a material processing system comprising a processing head configured to deliver a processing stream. The method includes calculating a start point and an end point of a shaping path proximate to the edge of the part based on a desired edge profile and determining a set of operating parameters to controllably impinge the processing stream about the edge of the part to execute the shaping path from the start point to the end point. The method further includes positioning the processing head normal to a surface of the part and controllably impinging the processing stream at the edge of the part, by the processing head, to shape the desired edge profile.

An ultrasonic cutter cuts edge chamfers of plate-shaped workpieces using a cutter head which forms an axis of rotation and a blade which extends from the cutter head and forms a cutting wedge, terminating in a straight cutting edge, between flank and contact faces determined by the wedge angle. In order to create advantageous structural conditions, the axis of rotation extending on the blade side of the flank face is at a distance from the flank face which is equal to or greater than the distance of the center of mass of the blade from the flank face and the cutting edge, extending in the direction of the axis of rotation, extends at a distance from the axis of rotation which corresponds at most to the blade thickness.

Provided are a cutting device and method. A blade receiving portion crossing a cord-embedded rubber sheet member is disposed in one surface side in a thickness direction of the rubber sheet member placed in a conveying mechanism. A cutting blade disposed in the other surface side is held by a holder that rotates about a turning shaft extending in the thickness direction of the rubber sheet member. In a state where a cutting-edge advancement direction turns about the turning shaft, a turning restoring force that restores the cutting-edge advancement direction to a preset moving direction is constantly applied by a turning restoring mechanism to the holder before cutting the rubber sheet member. The rubber sheet member is sandwiched in the thickness direction by the cutting blade and the blade receiving portion, and the cutting blade is moved in the extension direction of cords to cut between the cords.
