A machine tool for achieving a high degree of flexibility during workpiece processing comprises a machine bed with side walls arranged thereon, which respectively comprise a basic body with a front overhanging projection arranged thereon. Next, the method uses the lifetime information to generate representations of objects belonging to these collections. The panels employ one or more layers of a continuous phase resulting from the curing of an aqueous mixture of inorganic binder reinforced with glass fibers and containing lightweight filler particles.
