При отбортовке отверсти  сложной формы по ходу внедреии  пуансона в отверстие Г1-роисходит неравномерное (по длине окружности ) раст жение за счет формы кромки . Зоны впадин раст гиваютс  более интенсивно , чем зоны выступов, но материал из выступов имеет возможность за счет пластической деформации перетекать в зону впадин, предупреждени  лри этом образование трещин.When flanging a complex-shaped hole, along the route of inserting the punch into the G1 hole, uneven (along the circumference) stretching occurs due to the shape of the edge. The zones of the cavities are stretched more intensely than the zones of the protrusions, but the material from the protrusions has the ability, due to plastic deformation, to flow into the zone of the depressions, preventing this from forming cracks.

Число выступов - впадин зависит от толщины заготовки /i и диаметра пуансона дл  отбортовки D/I.The number of projections - cavities depends on the thickness of the workpiece / i and the diameter of the punch for flanging D / I.
