That is: minimum hole size and maximum shaft size.Least Material Condition (LMC)最小实体要求- implies that condition of a part feature of size wherein it contains the least (minimum) amount of material, examples, largest hole size and smallest shaft size. It isopposite to maximum material condition.Regardless Of Feature Size (RFS) - the condition where the tolerance of form, runout or location must be met irrespective of where the feature lies within its size tolerance.Projected T olerance Zone延伸公差带- applies to a hole in which a pin, stud, screw, etc., is to be inserted. It controls the perpendicularity of the hole to the extent of the projection from the hole and as it relates to the mating part clearance. The projected tolerance zone extends above the surface of the part to the functional length of the pin, stud, and screw relative to its assembly with the mating part.Tangent Plane相切面- indicating a tangent plane is shown.

This symbol is always shown with the vertical leg to the left.Counterbore/Spotface沉孔- is used to indicate a counterbore or a spotface. The symbol precedes the dimension of the counterbore or spotface, with no spaceCountersink埋头孔 - is used to indicate a countersink. The symbol precedes the dimensions of the countersink with no space.Depth/Deep深度- is used to indicate that a dimension applies to thedepth of a feature. This symbol precedes the depth value with no space in between.Square - is used to indicate that a single dimension applies to a square shape. The symbol precedes the dimension with no space between.

The symbol for spherical diameter precedes the size dimension of the feature and the positional tolerance value, to indicate a spherical tolerance zone.Controlled Radius可控半径 - creates a tolerance zone defined by two arcs (the minimum and maximum radii) that are tangent to the adjacent surfaces. Where a controlled radius is specified, the part contour within the crescent-shaped tolerance zone must be a fair curve without flats orreversals. Additionally, radii taken at all points on the part contour shall neither be smaller than the specified minimum limit nor larger than the maximum limit.Between - to indicate that a profile tolerance applies to several contiguous features, letters may designate where the profile tolerance begins and ends. These letters are referenced using the between symbol (since 1994) or the word between on drawings made to earlier versions of the Standard.Statistical Tolerance统计公差- is the assigning of tolerances to related components of an assembly on the basis of sound statistics (such as the assembly tolerance is equal to the square root of the sum of the squares of the individual tolerances). By applying statistical tolerancing, tolerances of individual components may be increased or clearances between mating parts may be reduced. The increased tolerance or improved fit may reduce manufacturing cost or improve the product's performance, but shall only be employed where the appropriate statistical process control will be used. Therefore, consideration should be given to specifying the required Cp and /or Cpk or other process performance indices。

差 线轮廓度是表示在零件的给定平面上，任意形状的曲线，保持
其理想形状的状况。 线轮廓度公差是指非圆曲线的实际轮廓线的允许变动量。也就 是图样上给定的，用以限制实际曲线加工误差所允许的变动范 围。

度
垂直度是表示零件上被测要素相对于基准要素，保持正确的 90°夹角状况。也就是通常所说的两要素之间保持正交的程 度。 垂直度公差是：被测要素的实际方向，对于基准相垂直的理 想方向之间，所允许的最大变动量。也就是图样上给出的， 用以限制被测实际要素偏离垂直方向，所允许的最大变动范 围。
位置公差 位置公差是指关联实际要素的位置对基准所允许的变动全量。
