Multi-remote system for efficient pre-processing of large surfaces
The global situation in terms of lightweight design strategies using various materials is characterized by an increasing demand for flexible manufacturing technologies for sheet-like materials and semi-finished parts that enable efficient solutions, predominantly in the automotive and aircraft industries. This, in turn, requires the development and testing of flexible equipment concepts for different manufacturing technologies, such as welding, cutting, material removal and structuring. These technologies should be applicable to processes and technologies for metal, plastics and textiles. To fulfill these conditions, laser-remote processes with radiation sources adapted to material and absorption properties offer a promising approach. The availability of highly-brillant cw laser sources of different wavelengths opens up new opportunities for remote applications.
Despite the very high quality of the lasers, the scanner working areas remain limited. Enlargements of the working field can be implemented by combining scanners with Cartesian kinematic systems. Current solutions using two-dimensional on-the-fly coupling of the scanner and the axis system can indicate the potential of an optimized axes overlap. The combination of large field scanners with highly dynamic spindle drives promises high-precision, high-speed manufacturing. For this reason, the aim was to open the system and technological possibilities for potential commercial users by means of a laser system for high-speed manufacturing of planar, moderately shaped, sheet metal and textile prepregs made of composite materials, metals and plastics using remote technology, with cw high-performance lasers of different wavelengths.
