Basics
- Part of the Open Source Digital Fabrication Construction Set
- A combinarion of the Open Source 3 Axis Wire-Cut EDM Machiene and the Open Source Robotic Arm Construction Set
- Allows for 5 (or more) axis EDM machining
- Good explanation + Demo in this video, at 13:26
Used For
- Same as the Open Source 3 Axis Wire-Cut EDM Machiene, but more DOF
Industry Standrds
Existing Open Source Designs
Minimum Viable Product
Basic Design
Housing
- Holds all the below together
Controller
- Controlls all components
- Rasberry Pi + Arduino + Any neccissary sheilds?
- Connects to IO Panel and any external controls (PC, Server, WWW, etc)
IO Panel
- Touchscreen
- Optional Mouse + Keyboard
Fluid Pump
- Recirculats the dielectric fluid
- Does this to promote circulation
- Also provides pressure to debris clearing jets
Fluid Filter
- Cleans Debris (Such as Metal Dust) Out of the Dielectric Fluid
- Hydrocyclone + Standard Oil/Water Filter Cartridge
- Should also include sensors before and after filtration to determine fluid + filter effectiveness
Work Surface
- The Workpiece is attached to this
Fluid Bath
- Allows the Work Surface and Work Piece to be submerged in dielectric fluid
- Could be permanent or a slide up design
CNC Gantry
- Holds and Moves the Toolpiece
- Standard D3D Axis?
Robotic Arm
- Attaches to CNC Gantry?
- Holds Toolpiece Allowing For More DOF Than 3
Toolpiece
- A device resembling two fingers holding dental floss
- Works with the power supply
Wire Feeder
- A device with two wire spools (one for feeding new wire thru and one for receiving spent wire)
- Also need to design/find the mechanism for shooting the string to the other side to remove the need for manual wire threading
Fluid Resevoir
- Holds Spare Fluid
- Also holds the contents of the fluid bath when not in use
