Terminology for parts
From apm

Things that influence terminology:
- (1) material: kind of material used
- (2) size: size of structure
- (3) type: structural or machine (or structure-of-machine)
- (UC) context of intended usage in convergent/hierarchical assembly
- (C) composability
- (M) exchange/replaceability
- (S) selfcontaindness
- (B) exterior geometry
Guideline for basic usage of common terms:
Strong suggestion: Try to not use these terms willy nilly unconcious about their meaning, but
rather try to use them based on what best fits the context.
- (0) part – perhaps the most general term
- (UC) assembly – something that already as been assembled from two or more parts
- (UC) sub-assembly – same as assembly but in the context of the next assembly level
- (UC) element – a part that is meant to become assembled or already is assembled into a bigger assembly
- (S) fragment – a part that in some sense can be considered a as a cutout of a bigger part => assembly needs welding/fusing/...
- (S) unit – something that is in some sense a self contained whole
- (B) block – a part with low aspect ratio exterior shape, usually convex – the term focuses on this external shape and is preferrably
- (C) component – something composable with other components (unless noted typically reversible)
- (M) module – something that can be exchanged/replaced with some that is internally different somehow
used for structural elements with not too much internal features of importance
Terms of this wiki
Going from special case to increasing generality:
Crystolecule or Gemstone-like molecular element (GME)
- (1) material: – gemstone-like but not necessarily with diamond-like structure
- (2) size: – large molecule sized
- (3) type: – can be structural element or machine element
- (UC) usage: – part that is meant to be part of bigger assembly
Diamondoid crystolecule
- (1) material: – diamond like structure
- (2) size: – large molecule sized
- (3) type: – can be structural element or machine element
- (UC) usage: – part that is meant to be part of bigger assembly
Diamondoid crystolecular machine element
- (1) material: – diamond-like structure (implies atomic precision AP)
- (2) size: – large molecule sized (implies lower nanoscale)
- (3) type: – machine part
- (UC) usage: – part that is meant to be part of bigger assembly
- (1) material: – gemstone-like but not necessarily with diamond-like structure
- (2) size: – as big as crystolecules or sometimes quite a bit larger – still nanoscale
- (3) type: – can be structural element or machine element – perhaps more machine elements since these may come with larger minimal size
- (S) usage: – self contained unit – not a fragment that needs to be fused – no unpassivated welding sinterface bonds left – all further assembly by reversible form closure or weak non-covalent bonds – (meant to be part of bigger assembly is implicit)
- (1) material: – gemstone-like but not necessarily with diamond-like structure
- (2) size: – large molecule sized
- (3) type: – typically structural – fragments of machine parts pose challenges like locking degrees of freedom for covalent welding
- (S) usage: – fragment that is meant to be part fused to bigger part (potentially irreversibly)
molecular machine element (MME) and molecular structural element (MSE)
- (1) material: – no constraints – though something with at least topological atomic precisition is typically assumed since molecular sized elements without any atomic precision hold limited functionality – that is: they can barely be called machine/structural elements
- (2) size: – large molecule sized
- (3) type: – can be structural element or machine element
- (UC) usage: – part that is meant to be part of bigger assembly
