Laser Cutting of Glass Tubes
This work presents a technique for cutting glass tubes, without the need of pre-heating or any posterior action. Rotating the piece under a laser beam focused on the surface at the zone were it’s to be cut, stresses will not act, and while the material is dissociated at the laser beam irradiated volume, at its frontiers the glass reduces his viscosity allowing that the resulting faces become smoothed.
