此为三极管上的印字与真实名称的对照表，焊接电路时用它来找零件。-This is the transistor on and the real name of the printing table of the welding circuit when the parts come with it.

借助激光测距技术、数控技术和计算机技术，将锥体零件的若干典型截面数字化，根据相关形位公差的定 义，利用计算机进行数据处理，求出被测零件的截面圆度、最大最小直径、垂直度等。- Using laser ranging technology, numerical control technology and computer technology, will taper parts some typical digital, according to relevant section of the

钣金件工程图的创建方法与一般零件基本相同，所不同的是钣金件的工程图需要创建展开视图-The creation method of sheet metal parts engineering drawing is basically the same as that of common parts, and the engineering drawing of sheet metal parts need to be created.

《公差配合与测量技术》是学习和研究互换性，围绕零件的制造误差和公差概念，合理地解决生产成本，产品质量和效益之间的关系。
