Abstract

PURPOSE:To improve cutting quality by moving an impulsive high energy beam on a processing line at the speed satisfying specific conditions to form plural pieces of holes, then cutting the working material along holes. CONSTITUTION:The working material 1 such as printed circuit board is set on a processing table 16 and the table 16 is driven by a driving motor 17 so that the impulsive high energy beam 11 is made movable relatively with the material 1. The relative moving speed (v) of the beam 11 is so set as to satisfy the conditions expressed by the formula with respect to the diameter (d) of the processed holes and pulse frequency (f), then boring by the beam 11 is executed. Since the beam moving speed (v) is controlled by the equation, the adjacent holes of the bored holes 2 connect to each other to form a perforation line. The material is then cut along the perforation line. The cutting is executed without contacting and the deterioration in the material quality at the cutting point is prevented. The cutting quality and workability are thus improved.
