- 2. • Fibre-, CO2- and Nd:YAG-lasers are the most commonly used in the field of metal processing. • Over the past decade, lasers have been developed into the state-of-the-art technology. • Developing of higher output powers without sacrificing the beam quality has been one important goal. • Other efforts have been focused on improving the drive technology of the motion system and improve material handling. • Predictions are that laser processes are based on improved speeds, no tool costs and unlimited flexibility – lasers will replace competing technologies.

- 14. CREATING ECONOMICAL DESIGNS • The cost of a sheet metal parts are determined on designing. • You can either save on material or manufacturing costs in production. • The goal is to combine the various production factors – the type of material, material consumption, production time and constructions . • One improvement can have a positive effect on a number of different areas.
- 15. CREATING ECONOMICAL DESIGNS • Minimize sheet thickness • Lower material costs, lighter weight and faster production • Use the same sheet thickness • Products be can manufacture from a single sheet • Maximize nesting potential • Design engineers can fit more parts on the sheet by designing the parts so that they “nest” inside each other • One part, many functions • Often, these parts only need some additional holes or larger recesses in order to perform a different task
- 16. CREATING ECONOMICAL DESIGNS • Why weld if you can bend? • Welding not only takes up valuable time, but also generates heat that could distort the work piece • Minimize clean up • Try to eliminate welding seams • Using laser welding helps to reduce finishing • YOU DESIGNED IT. NOW CAN YOU PRODUCE IT? • Keep in mind not only the costs of parts but also how it is going to manufacture
- 17. CREATING ECONOMICAL DESIGNS • Production simulations • Programming software enable users to simulate production • This allows design engineers to test sheet metal parts as often as necessary to identify problems • Knowledge transfer • Working together with colleagues in production • The designer learns about tolerances and bending processes
- 18. • Use positioning and joining aids • Using pegs and holes we can match the parts together • For welding we need simple jigs to hold the parts • Special bent tubes techniques create connections with the need of only few welds
- 19. Modern laser technology makes possible… • Bayonet coupling ensures orientation and reduces need for precision fixturing • Coding system to avoid possible assembly mistakes, accurate position.
- 20. Goals reached with laser technology: • Reduced heat distortion in cutting and welding • minimal shrinkage & distortion of the work piece • small heat affected zone • Narrow weld bead with good appearance flange • Narrow or no flange • reduction of component size / weight • Increased strength LASER TECHNOLOGY, Marc Kirchhoff spot • improved component stiffness / fatigue strength welding flange Kirchhoff 02.01.2014 welding
- 21. Goals reached with laser technology: • Lasers are utilized in prototyping • Increased process speed in joining & cutting • Increases productivity • Ability to weld in areas difficult to reach • non-contact, narrow access, single sided process • variety of part & weld geometries and materials
- 22. Goals reached with laser technology: • Cost savings in products and production • High productivity >> faster cycle time • Reduction of manual labour, less scrap, less re-work • Reduction of component material and weight • Eliminate second processes • Less energy • Reduced floor space – smaller investments • New and better constructions
