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。
公差与配合的注法与查表
公差与配合是机械制造中非常重要的概念，通过注法和查表可以确定零件的尺寸公差和配合关系。
以下是一般的注法和查表方法：注法（Tolerance Notation）：1.基本尺寸（Basic Size）：在图纸上标明的零件的理论精确尺寸。
2.上偏差（Upper Deviation）：表示零件尺寸允许超过基本尺寸的最大值，通常用大写字母表示，例如H。
3.下偏差（Lower Deviation）：表示零件尺寸允许小于基本尺寸的最小值，通常用小写字母表示，例如h。
4.公差（Tolerance）：是上偏差与下偏差之差，也就是公差=上偏差-下偏差。
5.配合公差（Fit Tolerance）：当上偏差和下偏差相等时，称为配合公差，通常用一个字母表示，例如H。
查表：1.国际制（ISO）标准查表：ISO标准有一系列的标准配合表，例如H7/g6，表示基本尺寸为H7，轴的上偏差为g6。
这些标准表中列出了各种不同的基本尺寸和配合的组合。
2.GB（国家标准）查表：国内的GB标准也有类似的配合表，通常使用“大中小”字母表示，例如H7。
3.ANSI/ASME标准查表：美国标准ANSI/ASME也有一系列的标准配合表。
示例：以ISO标准为例，H7/g6表示轴的基本尺寸为H7，孔的基本尺寸为g6。
这个组合表明，轴的尺寸可以在H7的上偏差和下偏差范围内变化，而孔的尺寸可以在g6的上偏差和下偏差范围内变化。
在设计中，选择合适的公差和配合关系是根据零件的使用要求和生产成本来决定的。
一些需要紧密配合的零件可能选择小一些的公差，而一些需要松动配合的零件可能选择大一些的公差。
表面符号公差与配合
1.工作物經過各種加工製造後，表面形成精粗不等的情形稱為表面粗糙度，表面粗糙度單位為μｍ（ 1 μｍ= 0.001 mm = 10-6 mm ）2.粗糙度種類：（R a、R z、R max）R a（中心線平均粗糙度）：在表面輪廓曲線擷取某一測量長度（基準長度），將範圍內上下面相加除以基準長度即能得到R z（十點平均粗糙度）：基準長度內表面輪廓曲線之第三高峰與第三低谷的和稱之R max（最大粗糙度）：基準長度內表面輪廓曲線之最高峰與最低谷的和稱之 中國國家標準（CNS）係採用中心線平均粗糙度，其粗糙度數字後不加a。
但若為十點平均粗糙度，則粗糙度數字後需加z；最大粗糙度，則粗糙度數字後需加s三者關係：4R a = R z =R max3.表面粗度值↙超光面：加工表面光滑如鏡面（範圍0.01a ~0.16a）↙精切面：幾乎福法以觸覺或視覺分辨加工表面稱之（範圍0.25a ~1.6a）↙細切面：加工之表面用手觸摸似甚光滑，但仍能由視覺分辨其刀痕（範圍2.0a ~6.3a）↙粗切面：表面可由視覺及觸覺分辨殘留之刀痕（範圍8.0a ~25a）↙光胚面：一般鑄造、鍛造、壓鑄、輥軋、氣焰、電弧切割等無血加工所得之表面（範圍32a ~125a）4.粗糙度等級（在數字前加N，一共分為12級）5.表面符號（標註時，數字及文字說明以朝上、朝左為原則）切削加工符號表面粗糙度加工方法之代表字或表面處理基準長度（單位為mm，若基準長度為0.8則可省略不寫）刀痕方向符號加工裕度6. 切削加工符號7. 刀痕方向8. 粗糙度數值表示法最大極限法上下極限法9. 表面符號標註原則應標註於圖形輪廓線外，但也可標註在槽或孔內圓柱、圓錐或孔之表面加工符號應標註在任一邊或其延長線上，不可重複 圓柱、圓錐或圓孔之表面符號以標註在非圓形視圖上為原則表面符號之省略：表面符號完全相同之二個或二個以上之加工面，可用一個指線分出二個或二個以上之指示端，分別指在不同之加工面上，並將相同之表面符號標註在指線上。

By applying statistical tolerancing, tolerances of individualcomponents 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.Datum Target目标参考特征- is a specified point, line, or area on a part that isused to establish the Datum Reference Plane for manufacturing and inspectionoperations.Target Point - indicates where the datum target point is dimensionally located on the direct view of the surface.。

Page: 1 of 34蔣君宏7-1公差( tolerance )製造一機件，不可能製成一絕對準確之尺寸。
例如製一直徑30mm之軸，以現有技術製成之軸的直徑必較30.0000 mm為大或小。
在應用上只要限定其實際尺寸在一個最大與最小尺寸範圍之內即可。
此一範圍，亦最大與最小尺寸間之差，稱之為公差，如圖7-1所示。
軸與孔均各有一個公差。
為方便起見，各件均給予一個標稱尺寸 ( nominal dimension ) 如圖7-1中之零線所示。
將軸或孔之最大與最小尺寸用其距離此零線的偏差表示之。
住零線以上的偏差為正 ; 在零線以下的偏差為負。
在一般表示公差的圖表上，只將公差範圍及零線表出，而不再將軸或孔之全部繪出。
如圖7-2。
ISO / R286-1962 制定長度由l mm至500 mm標準尺寸之基本分差之品級，以由5至18之數字表之。
例如品數為6之公差，簡寫作IT6 ( 即國際公差第6級)。
公差之單位以i表之，惟i並非一定數，而係隨直徑之大小而變化，如表7-1所示。
Page: 2 of 347-2 公差之標示法公差本身之大小既如上述以品級數字表之，而此公差對於零線的位置則用一或二個拉丁字母表之。
軸之公差採用小寫字母，孔之公差則採用大寫字母，參看圖7-3。
大體言之，軸之公差由a 至g 者，其拉丁字母決定上偏差在零線以下之位置，而由j 至zc 者，其拉丁字母決定下偏差之位置。
其中j 之下偏差在零線以下，k 之下偏差在零線或其以上。
自m 以後之下偏差則均在零線以上。
此等位置亦稱為基本偏差。
對於孔之公差而言，由A 至G 者，其拉丁字母決定下偏差在零線以上之位置，而由K 至ZC 者，其拉丁字母決定上偏差之位置。
J 之上偏差在零線以上，K 之上偏差在零線或其以上，M 之上偏差在零線或其以下。
自N 以後之上偏差則均在零線以下。
js 或JS 之上下偏差適對於零線為對稱。
最主要之公差則為h 與H 。
軸之h 公差，其上偏差恰在零線。
