The disclosure relates to systems and methods for machine-cutting workpieces in plate form or bar form and also to a machine tool, with a laser machining device, and a workpiece support, by which a workpiece to be machined in the laser machining device is received, and with a workpiece moving device, by which the workpiece to be machined is held and moved in relation to the laser machining device, wherein with a machining head a laser beam is directed onto the workpiece to be machined and a clearance or recess is introduced into the workpiece and the clearance is machined with a flow drill and widened to a final size of a borehole.

Methods and machine tools for machine-cutting workpieces in plate form or bar form

A condition or detecting a change in the condition of an optical element of a laser arrangement is detected. An ultrasonic signal is coupled into an optical element such that the ultrasonic signal travels along a path within the optical element, and a transit time or a change in transit time for the ultrasonic signal to travel along the path within the optical element is detected.
