DURCH DAS NUTENWELLUNGSVERFAHREN HERGESTELLTER RÜCKSTRAHLER MIT GESTEUERTER DIVERGENZ

摘要

A ruling of cube corner elements comprising intersecting ruled vee-grooves is characterized in that at least one of the vee-grooves is made such the substrate being ruled and the cutting tool are oscillated with respect to one another during the ruling of the vee-groove.
