Design for assembly reduces parts and time.
Mechanical fasteners, adhesives, welds, rivets, snap-fits and clinching join parts. Choose by load, disassembly, materials, cost and environment. Design for assembly reduces part count and orientation difficulty; automation uses feeders and robots.
Car bodies combine spot welds, adhesives and rivets.
Assembly is often the most expensive part of making a product, so designing for easy assembly reduces cost and errors.

Assembly is often the most expensive part of making a product, so designing for easy assembly reduces cost and errors.
A method that reduces part count, simplifies handling and makes parts self-locating, so assembly is faster and more reliable.
Each part adds cost, inventory and assembly steps, so fewer parts usually lower the cost and the number of possible faults.
Typical applications include reducing the number of fasteners in a housing by using snap fits, designing parts that can only go together in one correct orientation and planning an assembly sequence that avoids reaching into closed areas.
Study "Semiconductor fabrication" first (topic 30 of 102 in Manufacturing, Robotics & Systems). It covers the groundwork this topic builds on.
Bolted vs bonded joints. Torque control. Poka-yoke.
Car bodies combine spot welds, adhesives and rivets.
The next topic is "Design for manufacturing", which builds directly on this one.
It is classed as Beginner in Manufacturing, Robotics & Systems (topic 31 of 102). It is an entry-level topic. It relies only on basic school mathematics and the ideas introduced earlier in this discipline.
