几何产品规范(GPS).锥体尺寸和公差注法

[中文适用范围]： 本国际标准规定了适用于圆锥（直角圆锥）的图形表示，以定义其尺寸或规定其公差。就本国际标准而言，“圆锥”一词仅适用于直角圆锥（任何与公称圆锥轴线垂直的平面相交都是圆）。注 1 为简单起见，本国际标准仅表示截头圆锥。但是，本国际标准可适用于其范围内的任何类型的圆锥。注 2 本国际标准并非旨在阻止使用其他尺寸和公差方法。 [外文原描述]： ISO 3040:2016 specifies graphical indication applicable to a cone (right-angle circular cones) to define its dimensioning or to specify its tolerancing. For the purposes of this International Standard, the term "cone" relates to right-angle circular cones only (any intersection by a plane perpendicular to the axis of the nominal cone is a circle). NOTE 1 For simplicity, only truncated cones have been represented in this International Standard. However, this International Standard can be applied to any type of cone within its scope. NOTE 2 This International Standard is not intended to prevent the use of other methods of dimensioning and tolerancing.
