Abstract: In a method for severing a solid body, a defined contour is stored in a control unit configured to detect contour breaches and to avoid contour breaches. A high-energy beam is moved along a contour on a surface of the solid body, with the surface of the solid body facing the high-energy beam, to produce with the high-energy beam a cutting gap. The contour on the surface is compared with the defined contour stored in the control unit, and avoidance of the contour breach is automatically deactivated when the contour on the surface of the solid body matches the defined contour and a contour breach is detected. Otherwise, the contour is omitted. Advantageously, the high-energy beam travels along the contour with an averaged line movement.
