The autocrafting table is used to construct factories. It works like a regular workbench. You can place items in the autocrafting table and pull out the resulting item manually.
However, you can also insert and extract items with Pipes. This is where the autocrafting table gets it's name. You can insert or extract items from any side with the use of a Wooden Transport Pipe and either a Redstone Engine, Stirling Engine, or a Combustion Engine. For most applications the Redstone Engine is most practical.
