<div style="color: black; text-align: left; margin-bottom: 10px;"><img src="https://p3-sign.toutiaoimg.com/tos-cn-i-qvj2lq49k0/19ce1a3708624613b31b853833f202a9~noop.image?_iz=58558&from=article.pc_detail&lk3s=953192f4&x-expires=1728032619&x-signature=EaPNoEhP78iL3mD3ENMg3rE5fKg%3D" style="width: 50%; margin-bottom: 20px;"></div>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">你以为它是表面粗糙度,其实它在图纸符号中是有“牌坊”!</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">【中文名<span style="color: black;">叫作</span>】未定义形状边</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">【英文名<span style="color: black;">叫作</span>】Edges of undefined shape (basic indication)</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">【参考标准】GB | ISO</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">【符号描述】本符号属于未定义形状边的基本修饰符。<span style="color: black;">经过</span>附加符号(+、-、±),数字以及标注位置(在“∟”的上边和/或右边),<span style="color: black;">能够</span>表达未定义形状边的三个基本要素,分别是类型(毛刺、过渡状态和侧凹),方向和尺寸。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">【符号应用】符号应用从以下两点来阐述,阐述前先帮<span style="color: black;">大众</span>提出一个术语边:边 - 两个表面的交线。 提它不是小看各位,是让各位脑袋里稍微想一下边,更有利于下面的理解。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">1. 未定义形状边的类型(<span style="color: black;">针对</span>内/<span style="color: black;">外边</span>边)</p>

<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">2. 未定义形状边符号的标注<span style="color: black;">能够</span>应用于以下三种<span style="color: black;">状况</span>:</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">对一条边进行单独标注;</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">对一个零件轮廓上的所有边分别进行单独标注;</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">对零件的所有或<span style="color: black;">重点</span>的同类边进行集中标注。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">单独的标注直接指向用于<span style="color: black;">暗示</span>与投影面平行或垂直边的一条线或一个点(见图2a-2c)。集中标注只对同类边标注一次,且靠近所标的视图或标题栏(见图2d-2h)。</p>
