形位公差中英文对照
形位公差中英文对照设计手册——形位公差符号对应英语Straightness直线度- a condition where an element of a surface or an axis is a straight line.Flatness平面度- is the condition of a surface having all elements in one plane.Roundness圆度- describes the condition on a surface of revolution (cylinder, cone, sphere) where all points of the surface intersected by any plane.Cylindricity圆柱度- describes a condition of a surface of revolution in which all points of a surface are equidistant from a common axis.Profile of a Line线轮廓度- is the condition permitting a uniform amount of profile variation, ether unilaterally or bilaterally, along a line element of a feature.Profile of a Surface面轮廓度 - is the condition permitting a uniform amount of profile variation, ether unilaterally or bilaterally, on a surface. All Around Symbol全周符号 - indicating that a tolerance applies to surfaces all around the part.Angularity倾斜度- is the condition of a surface, axis, or centerplane, which is at a specified angle from a datum plane or axis. Perpendicularity垂直度 - is the condition of a surface, axis, or line, which is 90 deg. From a datum plane or a datum axis.Parallelism平行度- is the condition of a surface, line, or axis, which is equidistant at all points from a datum plane or axis.Position Tolerance位置度 - defines a zone within which the axis or center plane of a feature is permitted to vary from true (theoretically exact) position.Concentricity同轴度 - describes a condition in which two or more features , in any combination, have a common axis.Symmetry对称度- is a condition in which a feature (or features) is symmetrically disposed about the center plane of a datum feature. Runout圆跳动- is the composite deviation from the desired form of a part surface of revolution through on full rotation (360 deg) of the part on a datum axis.Total Runout全跳动 - is the simultaneous composite control of all elements of a surface at all circular and profile measuring positions as the part is rotated through 360.Maximum Material Condition (MMC) 最大实体要求- is that condition of a part feature wherein it contains the maximum amount ofmaterial within the stated limits of size. 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. The symbol is placed in the feature control frame following the stated tolerance.Free State Variations自由状态变形 - is a term used to describe distortion of a part after removal of forces applied during manufacture. Diameter直径- indicates a circular feature when used on the field of a drawing or indicates that the tolerance is diametrical when used in a feature control frame.Basic Dimension基本尺寸 - used to describe the exact size, profile, orientation or location of a feature. A basic dimension is always associated with a feature control frame or datum target. (Theoretically exact dimension in ISO)Reference Dimension参考尺寸- a dimension usually without tolerance,used for information purposes only. It does not govern production or inspection operations. (Auxiliary dimension in ISO) Datum Feature参考特征- is the actual component feature used to establish a datum.Dimension Origin尺寸源- Signifies that the dimension originates from the plane established by the shorter surface and dimensional limits apply to the other surface.Feature Control Frame公差控制框- is a rectangular box containing the geometric characteristics symbol, and the form, runout or location tolerance. If necessary, datum references and modifiers applicable to the feature or the datums are also contained in the box.Conical Taper - is used to indicate taper for conical tapers. This symbol is always shown with the vertical leg to the left.Slope坡度- is used to indicate slope for flat tapers. 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. Number of Places位置数量- the X is used along with a value to indicate the number of times a dimension or feature is repeated on the drawing.Arc Length弧长- indicating that a dimension is an arc length measured on a curved outline. The symbol is placed above the dimension.Radius半径- creates a zone defined by two arcs (the minimum and maximum radii). The part surface must lie within this zone.Spherical Radius球半径 - precedes the value of a dimension or tolerance.Spherical Diameter球直径- shall precede the tolerance value where the specified tolerance value represents spherical zone. Also, a positional tolerance may be used to control the location of a spherical feature relative to other features of a part. 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。

位置度是表示零件上的点、线、面等要素，相对其理想位置 的准确状况。 位置度公差是：被测要素的实际位置相对于理想位置所允许 的最大变动量。
圆跳动是表示零件上的回转表面在限定的测量面内，相对于 基准轴线保持固定位置的状况。 圆跳动公差是：被测实际要素绕基准轴线，无轴向移动地旋 转一整圈时，在限定的测量范围内，所允许的最大变动量。

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。

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。
