Assembly drawings
Show how parts fit together in their working positions: a sectional assembly with a parts list (item number, name, material, quantity) and balloons referencing each part.
Detail drawings
Each part drawn separately with full dimensions, tolerances, materials and finishes – ready for manufacture.
Machine elements
- Fasteners: bolts, nuts (locknuts, slotted nuts with split pins), studs, set screws, washers, keys and keyways, rivets.
- Shafts and couplings, bearings (plain and rolling element), pulleys and belt drives, gears (spur, helical, bevel, worm), springs and cams.
- Pipe fittings and valves.
Reading drawings
Interpret orthographic and sectional views to visualise the assembly, then produce the requested views (often a sectional elevation from given part drawings).
Exploded views
Pictorial views showing parts separated along their assembly axes, used in instruction manuals.
Check yourself
- What information is given in a parts list?
- What is the purpose of a split pin with a slotted nut?
- Distinguish between an assembly drawing and a detail drawing.
Show answers
- Item number, part name, material and quantity (sometimes standard references).
- To lock the nut and prevent it from loosening.
- An assembly drawing shows parts fitted together; a detail drawing gives full manufacturing information for a single part.
