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.
