Interpreting Detail Drawings (读零件图)

Purposes and requirements for drawing interpretation(读图的目的和要求)

 Purposes for drawing interpretation(读图的目的)

When a designer designs parts,he/she needs to refer to the pertinent machine part drawing, so that one can interpret the drawing. When a worker produces parts,he/she needs to interpret the drawing in order to figure out their structures, shapes, dimensions and technical requirements. When inspectors and maintenance workers inspect or maintain parts, they need to interpret the drawing to assess whether the parts meet technical requirements. In short, all technicians should be ableto interpret drawings.

工程设计人员在设计零件时,经常需要参考同类机器零件的图样,这就需要会看零件图。生产制造技术人员在制造零件时,也需要看懂零件图,想象出零件的结构、形状,了解各部分尺寸及技术要求等,以便加工出零件。检验、维修技术人员在检验或维修零件时也需要查看零件图,以判断该零件是否达到技术要求。总之,从事各种工程技术专业工作的技术人员,必须具备读零件图的能力。

Requirements for interpreting part drawings(读零件图的要求)

 1) Understanding the part name, material, and function (including functions of each section).

2)Understanding the structural shapes of each section of the part.

3) Understanding the dimensioning and technical requirements. One also needs to analyze and understand the representations of various views.

1)对零件图的名称、材料和功用(包括各组成形体的作用)要有所了解。

2)读懂零件各部分的结构形状。

3)能理解图中的尺寸注法,并了解零件的技术要求,分析零件的视图
