椭圆封头毛坯直径的计算,一般遵循等表面积的原则,其计算公式如下: ……(1)式中α+β=90°(见附图) φ—展开毛坯直径(理论数值,未考虑加工余量,下同)
The calculation of the diameter of an oval head blank generally follows the principle of equal surface area. The formula is as follows: (1) where α + β = 90 ° (see the attached drawings) φ-blank diameter to be unwound (theoretical value, Margin, the same below)
