Laserová předúprava pro lepení sendvičové struktury s podporou CNC

Abstract

This bachelor thesis deals with the laser pretreatment of the surfaces on aluminium sheets used for the construction of a sandwich structure using bonding. The thesis also includes a section dealing with the automation of the laser head movement using a CNC centre. The first chapter of the theoretical part describes the sandwich structures and their properties. The second part focuses on different methods of surfaces pretreatment intended for bonding. The final third and fourth part of the theory deals with the bond and then its construction. The practical part is devoted to the automation of the laser using a CNC centre, lasering, bonding and testing of sandwich structures. The aim of the whole thesis was to prepare the sandwich structure using CNC-assisted laser, evaluate this preparation process and compare the types of bonding by mechanical testing.
