| ABSTRACT |
| Thin-sheet blanks made of aluminum (in particular, AMg2-N), titanium (VT-15, VT-19) or
stainless (12X17) alloys are widely used in the production of honeycomb panels in the aviation and
space industries. Foil (thickness 0.025-0.055 mm) is used for the production of fillers for cellular
sandwich panels; it is pre-perforated with holes of 0.05-0.18 mm and laid out in a corrugated box
with adhesive strips. The possibility of making holes by the laser jet method is considered, as it
precedes the occurrence of mechanical damage and thermal defects of the surface adjacent to the
treatment zone.
It is shown that the Water Jet Guided Laser (WJGL) is an effective and efficient method of
obtaining profile holes in the fillers of cellular panels and in the panels themselves, which is
characterized by high productivity and allows obtaining holes without thermal and mechanical
defects. The method can be used both for foil fillers and for metal panels made of stainless steel up to
1.5 mm thick. |
