That is: unfold size = a straight edge length + B straight edge length - bending coefficient, these formulas are commonly used in our production cutting!For example: the length and width are 1000mm, the four sides are 90 degrees, and the folding edge is 20mmFor ordinary aluminum veneer, many people think that the opening size is 1040 * 1040mmHowever, the actual cutting is 1034 * 1034mm. Because of the 90 degree bending of 2.0, the bending coefficient without slotting is 3.0 mm, and the length and width of simply supported plates on four sides are bent by two knives, and the cutting size should be reduced by 6 mm
