Abstract

1. Paragraph description of the OSAT - why is it Appropriate? What need does it fulfil? Are there case studies you have found of a technology being used successfully?
2. Picture of completed print using your printer

The goal of this design is to allow a lubrication and chip clearing module addition to a CNC router. This system consists of an external unit which served to feed the air and lubrication with a actuating arm mounted on the spindle to better direct the fluid/air onto the tool piece. This simple and easy solution would allow individuals to use their CNC Router with metal.

Tools needed for fabrication of the OSAT

1. MOST Delta RepRap or similar RepRap 3-D printer
2. Soldering Iron to use filament welding method to connect parts
   1. Use solding iron to melt filament together. A short piece can be ran through holes and melted on either end. Another option is to melt along the edges where two parts meet.

It is assumed that the "first step" before these instructions is to acquire all materials needed from the Bill of Materials.

1. Arm Sub-Assembly

   1. 

      Use filament welding method to connect "Socket Flange" to "CNC Mount"

   2. 

      

      Use filament welding method to attach both "End Hose Clip" pieces to the other "Socket Flange"

   3. 

      Use the "Socket Ball Long Adjusted" (2), "Ball 40mm Ball Vert" (1), and "Locking Nut" (4) to assemble complete arm.
2. Parametric Peristaltic Pump Sub-Assembly
   1. x
   2. y
   3. Cut tubing to appropriate length and attach
3. Fan Sub-Assembly
   1. x
   2. y
   3. Cut tubing to appropriate length and attach
4. Final Assembly
   1. Place Parametric Peristaltic Pump Sub-Assembly in Box
   2. Secure to box with ?
   3. Place Fan Sub-Assembly in Box
   4. Secure to box with ?
   5. Run tubing from two assemblies to the "CNC Mount". Feed through the holes and place in "End Hose Clip"
   6. Adjust arm to angle tubing in the desired direction and tighten "Locking Nut"s.
