There are two types of assembly blueprints commonly used in machine shops: General Assembly and Detail Assembly (next page).
The General Assembly blueprint is the most common, and shows the final assembly of the product, and identifies all the individual parts by arrows and numbered balloons.
The example General Assembly blueprint shown above contains the following:
- 2 machined parts (items 1 and 7)
- 2 subassemblies (items 2 and 3)
- 3 fabricated parts (items 4, 5, 8)
- 1 type of bolt (item 10)
- 1 type of nut (item 6)
- 1 type of adhesive (item 9)
Altogether, 10 different items are indicated in the B/M items column. By adding the numbers in the quantity column it can be seen that there are 16 individual pieces, plus an unspecified amount of adhesive, to build the assembly.
Detail blueprints of the machined and/or fabricated parts will be found on separate blueprint sheets with different blueprint numbers.
