METHOD AND DEVICE FOR THE FRACTURE SEPARATION OF A WORKPIECE

摘要

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).
