在表7’中摘要列举了表面粗糙度标注的有关规定及图例。
表7表面粗糙度的标注方法及示例当零件的大部分表面具有相同的表由 粗糙度要求时，对其中使用最多的一 种代（符）号可统一注在图样的右上 角，并加注‘其余”两字，且应是图 样上其它代（符）号高度的1.4倍代号中数字注写方向应与尺寸数字方向一致；倾斜表面的代号及 数字标控方向应符合图右规定标注规定及说明例图4当地位狭小不使标注时.可引出标注;细线相连的不连续同一表面.只要标注5零件所在表面具有相同的表面粗糙度要求，在右上角统一标注代号简化注法；为了简化标注方法，或标注位置受到限制时.可以标注简化代号，但必须在标题栏附近说明这些简化代号的意义101112 省略注法当仅有同一种表而粗糙度的去除材料加工的在面.以及不会除材料的表面时，可采用省略注法，但必须在标题附近说明这些省略代号的意义零件上重复素（孔，槽，齿等）的表面只标注其中一个。
连续表面只注一次同一表面具有不同的表面和粗糙度要求时，须用细实线画出其分界线.并注出相应的表面粗糙度代号和尺寸中心孔的工作表面，键槽的工作面.倒角、圆角的表面粗糙度代号，可以简化标注齿轮、渐开线花键的工作表面没画出齿形时.表面粗糙度代号注在分度线上即即即"明虫&&易但V 一q3/I~iiLJiLUiyjizfliio 0丛13螺纹没画出牙型时.表面粗糙度代号注在尺寸线或引出线上需要将零件局部热处理或局部14涂（镀）时，应用粗点划线画出其范围并非标注相应的尺寸，也可将其要求并写在面粗糙度符号内即葩0 ◎眠口。
