  2. First calculation method : doing horizontal projection drawing on drawing piece, k value is introduced by area equation of projection drawing, k value is obtained by area equation, along outline of projection drawing to add k value, that is, outline shape of blank drawing, principle area - equal and shape similar are used. second calculation method : along outline of drawing piece horizontal projection drawing, to do normal line of penetration line for wantonly point of this point, to obtain high of drawing piece on this point normal line, point and point is to form outline shape of blank

    計算方法之一為k值法:作拉深件水平投影圖,在該投影圖面積方程中引入k值,利用面積相等原理解方程,求得k值,沿水平投影外沿加上k值,即為毛坯圖的外廓形狀。計算方法之二為拉深線法:沿拉深件水平投影圖外廓,在任意點作該點切線的法線,在該法線上以該點拉深件的高度為量,在法線上取截點。
