The flow of design drawing that enables accurate assembly work without high levels of training is organized below.

Explanation of the example

Explanation is along a~d shown above.

(a) Identify machine section(s) requiring accuracies.

Applicable section is the XY table in this case.

(b) Visualize the assembly process. (see [Fig.1])

(c) Identify parts that affect accuracies from the assembly drawing.

The parts are the 3 red lettered parts from b) above. (see [Fig.1])
　＊Base
　＊Y axis base mounting plate
　＊Y axis base

(d) Match the assembly datum features of parts and enter into drawings the dimension specifications that enable high accuracies.

This is shown on [Fig.1]. The datum shown is referenced for specifying locations of assembling reference dowel holes.
