Zusammenfassung:	A method and a device for the fracture separation of a workpiece and a workpiece fracture-separated by the method according to the invention or with the device according to the invention are disclosed. According to the invention, formed at a distance from a fracture separating notch (16, 18) is at least one fracture directing notch (24), which plays a part in determining the path followed by the fracture separating plane (28). The device for the fracture separation of the workpiece has a laser unit for forming the fracture separating notch (16, 18) and a machining unit for forming the fracture directing notch (24). Se describen un método y un dispositivo para separación por fractura de una pieza de trabajo y una pieza de trabajo separada por fractura por el método de acuerdo con la invención o con el dispositivo de acuerdo con la invención. De acuerdo a la invención, a una distancia desde una muesca de separación por fractura se forma al menos una muesca dirección de fractura, que juega una parte al determinar la ruta seguida por el plano de separación por fractura. El dispositivo para separación por fractura de la pieza de trabajo tiene una unidad láser para formar la muesca de separación por fractura y una unidad de maquinada mecánico para formar la muesca de dirección de fractura.
