Sorry about that, I'm at work and the idea suddenly came to me, wanted to get it down before I forgot. Maybe an example would help.Please elaborate; I do not fully understand.
In my workshop, for instance, making TRISO fuel requires a grinder, a furnace, and an autocrafting table, at least 5 logisticspipes, basic pipes connecting them, 2 power sources, and proper power conversion. Instead of this complex mess, I thought, why can't we have an assembly line similar to real life manufacturing? In this case, dump coal onto a conveyor block. This moves it to the next conveyor block where a grinder is placed in the module slot. It processes it, outputs coal dust to the next conveyor block, which has a furnace&friction heater. It processes it and sends out graphite. On a separate assembly line, conveyor>grinder turns uranium ingots into dust. These two lines then merge on a junction conveyor, which drops all the items to the last conveyor block containing a crafting table in the modular slot. This outputs TRISO fuel.
This way, while it'd take a few more blocks (8+control), there'd be no piping mess other than the initial and final products, only one power input, and it'd look cool watching things move along the line. This is a simple example, of course, it could get much more complex with things like turbine parts or auroral batteries. It doesn't necessarily need module slots, individual conveyor 'types' could be crafted instead (basic conveyor+grinder=grinder assembly unit or somesuch.)
Hopefully this makes more sense. Another way to conceptualize it is if one were to chain a ton of TE or Engineer's Toolbox machines together but with RoC/ReC machines, more control over the process, and more risk/reward.
