Another Profile Tip, Another Circular Runout Tip

轮廓度/圆跳动/全跳动之间的区别如下表所示，
圆跳动——给出的是被测圆柱的任一圆截面相对于基准轴线的最大变动量的要求。
全跳动——给出的是整个被测圆柱相对于基准轴线的最大变动量的要求，通常全跳动公差要大于圆跳动公差，全跳动公差控制除了尺寸之外的几何公差。
轮廓度——若给出了基准要求和基本尺寸要求，是在相当于在给出了全跳动公差要求的基础上，还对尺寸给出了限制要求。





A lot of confusion exists over the meaning of the geometric tolerances shown in the chart. February's Tip illustrated possible inspection methods for position and concentricity. This month's Tip continues with sample inspection methods for circular and total runout and profile. these drawings is the same, the designer should consider the needs of those who will read the print when placing dimensions.







圆跳动是对被测圆柱的任一截面圆（旋转）独立检测，圆跳动检测不到尺寸的变化，被测圆柱的任何桶形，腰形或锥形都将被忽略，
Circular runout requires inspecting circular elements individually. Because of this, circular runout will not detect changes in size. Any barreling, waisting or taper should be ignored. These conditions will be controlled by the size tolerance.
全跳动是对整个被测圆柱（旋转和移动）进行检测，全跳动能检测到尺寸的变化（例如，桶形，腰形或锥形）。虽然控制了尺寸的变化，但是圆柱的实际尺寸还是由尺寸公差来控制。若被加工的圆柱特征的尺寸较小，但由于同心度较好，全跳动公差可以相对大些。全跳动除了尺寸，对形状，方向和位置都给出了公差规范要求。
对给出了基本尺寸的轮廓度来说，这种轮廓度不仅对尺寸给出了公差规范要求，而且控制了被测特征的所有几何公差要求。
Total runout requires determining the full indicator movement over the entire feature. Total runout, therefore, detects any changes in size, i.e. barreling, waisting or taper. Although changes in size are controlled, the actual size of the feature is determined and controlled by the size dimension and tolerance. A feature may be manufactured to a very tight size tolerance but due to eccentricity, the runout could be large. Total runout controls form, orientation and location but not size. Profile controls everything that total runout does as well as size if the size dimension is made BASIC.
