Try putting the Sorting Machine on "All stack, Sequential" (the second option - see the wiki page for an image) and in each stack in the GUI put the recipe amounts. Then color code each stack with a distinct color, and make sure the sorting machine is directly adjacent to the chest. Now when you pulse the sorting machine with redstone current it will start with stack one, pull the correct amounts out, color code them, and dump them into the tube network. Also make sure to color-code each tube just before the target crafting bench so the colored items know where to go.

You can also use Retrievulators instead of sorting machines (these can be configured to suck out the exact amount needed for a recipe and will automatically stop when told - make sure to read the wiki page). These work well in conjunction with Automatic Crafting Tables. The disadvantage is they make your setup larger, but they are extremely useful and controllable.
