Abstract

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 an 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. The Arduino Sketch can be found here GitHub

  1. Arm Sub-Assembly
    1. Use filament welding method to connect "Socket Flange" to "CNC Mount"
      CNC Mount and Socket Flange
    2. Use filament welding method to attach both "End Hose Clip" pieces to the other "Socket Flange"
      End Clip Top
      End Clip Bottom
    3. Use the "Socket Ball Long Adjusted" (2), "Ball 40mm Ball Vert" (1), and "Locking Nut" (4) to assemble complete arm.
      Fully Assembled Arm
  2. Peristaltic Pump Sub-Assembly
    1. Feed Lubrication Tube through Pump so the desired length is hanging out into lubrication bottle
    2. Mount to lubrication bottle
    3. Trim tubing to appropriate length (length in this case is from the router head to the box location)
      Peristaltic Pump Front
      Peristaltic Pump Back
  3. Fan Sub-Assembly
    1. Cut and Strip neutral wire of air mattress pump to place relay in the middle
      Relay Wiring
    2. Glue Nozzle Adapter to the pump output
      Nozzle Attachment
    3. Cut tubing to appropriate length and attach
  4. Electronics
    1. Wire Stepper motor to Arduino Uno (wiring)
    2. Wire relay circuit to Arduino Uno (wiring) and connect the stripped ends of the power cable to the NO contacts.
    3. Compile and upload the Arduino sketch to the Ardino Uno and connect the board to a 5V power supply
      Full Electronics
  5. Final Assembly
    1. Place Peristaltic Pump Sub-Assembly in Box
    2. Secure to box with glue/tape/zip ties
    3. Place Fan Sub-Assembly in Box
    4. Secure to box with glue/tape/zip ties
    5. Run tubing from two assemblies to the "CNC Mount". Feed through the holes and place in "End Hose Clip" Adjust arm to angle tubing in the desired direction and tighten "Locking Nut"s.
      Final Arm Assembly

Common Problems and Solutions

  • The End Clip could be modified to be completely circular to better hold the tubing.
