Because of the membrane structure of the cutting process in any case there will be errors, a variety of angle changes more, and the processing precision requirements are very high, so the production process to strengthen quality management, to ensure quality accuracy. The processing should pay attention to the following:

1, because the use of the curved face mask unit, if the adjacent unit curvature is very large, indicating that in this position, the surface distortion is very serious, if the crop is not cut off here to start again, then the boundaries of the cutting module will have a large arc. The approximate direction of geodesic can be determined from the trend of the curvature of adjacent units.

2. The width of the membrane material should be taken into account when the planar mesh is divided in the process of shape analysis. As far as possible to make a film containing the membrane unit is complete, otherwise, through interpolation calculation to determine the location of the module boundary point.

3, the direction of the border if the boundary is relatively straight, consider using the long side of a module as the boundary. Otherwise only the short edges of multiple modules can be stitched together into this boundary.

4, because the membrane has a light transmittance, so the actual structure we can clearly see the weld seam, the layout of the cutting seam must be reasonable, the rules, it is best to form some beautiful patterns to increase the aesthetic degree of the structure; if the membrane surface is set with a pressure cable or a cord, then it is best to make the cutting seam with the cord or the So that the cable does not disrupt the pattern layout of the weld.
