Composite parts consist of several layers, that are placed on top of each other in a tool. The number of layers depends on the local strength needed to absorb inner and outer forces.
As a result, many objects have irregular surfaces, meaning a different number of layers to be stacked.
Up to now, mechanical templates (paper, metal, plastics, ...) or measurement instructions have been used for positionning of cut-outs. But this work is time-consuming. Changes in design cause the need of new
templates or changed instructions.
CAD data, available from product design, are the basics for projection of outlines. If the design changes, only the projection files have to be adjusted.
Using the generated projection files and being calibrated on a tool surface, the projectors display the outlines as a laser line.
