Mapping Parts (零件的测绘)

To map a part drawing based on an existing physical part, one may first measure its dimensions, figure out its technical requirements, and then elaborate the working drawing according to sketches from the measurement. Part mapping is useful for duplicating an existing part or repairing damaged parts.

零件的测绘是根据实际零件画出草图,测量零件各部分的尺寸,确定技术要求,再根据草图画出零件的工作图。一般在仿制机器和修配损坏的零件时,需要进行零件测绘。

This chapter mainly focuses on mapping methods, steps and common measuring techniques.

本节仅讨论测绘的方法、步骤及常用的测量方法。
