Basics
- Part of the Open Source Digital Fabrication Construction Set
- An electric discharge machining device (EDM)
- Uses a die, and high voltage electricity to precicely erode away material using the resulting plasma
Used For
- Mold Making
- Die Making
- Machining Difficult Metals Like Tungsten
- Hole Drilling
- All of this with very high tolerances
Industry Standards
MC Machinery
Sodick
Makio
Existing Open Source Designs
- PS Eric Here, there are many designs so I just put these 3, Feel Free to Add More
Hackaday Article
Dedicated DIY EBM Website
Instructable 1
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?
Toolpiece
- A Hollow Cylender (Similar to a drill chuck) that allows various sinkers to be attached
- Works with the power supply
- Quickchange optionally
Fluid Resevoir
- Holds Spare Fluid
- Also holds the contents of the fluid bath when not in use
