Othermill

Othermill

The Othermill is a small 3-axis CNC (Computer Numerical Control) milling machine allows you to create 2D and 3D objects out of durable materials.

Warnings:

  • The Othermill must not be used to cut fiberglass (PCB Materials) or carbon fiber, as these create hazardous dust and will shred your lungs and may foul the machinery.
  • Observe recommended spindle speeds, cutting rates and maximum pass depths.
  • Do not bypass safety interlocks.
  • Do not stick anything into the machine while it’s running.
  • No cutting fluid or other coolant / lubrication.
  • Vacuuming out the swarf after your cut is mandatory.

Materials:

The Othermill is a general-purpose 3-axis CNC mill and can mill or engrave almost anything softer than steel that fits in 5.5 inches x 4.5 inches x 1.35 inches (13.97 cm x 11.43 cm x 3.43 cm) build area.

Allowed Materials:

  • Custom PCBs out of coper-clad FR-1 laminate
  • Plastic (HDPE, Delrin, acrylic, polycarbonate)
  • Wood
  • Linoleum (used for stamps)
  • Aluminum (generally 6061)
  • brass (free-machining alloys like C360)
  • Machining wax
  • Polyurethane modeling foam

    Disallowed Materials:

  • Unknown alloys of aluminum or brass
    • Some are not machinable
  • Steel, iron, titanium
    • Will break the bit
  • Magnesium
    • Extreme fire hazard
  • Fiberglass (including FR-4), carbon fiber
    • Abrasive dust – health and mechanical hazard
  • Stone, glass
  • Food of any kind
    • Othermill is not food safe.
    • Food molds are okay.

CAM:

CAM (Computer-aided manufacturing) is the process of going from a CAD model to machine-specific instructions on where to put the tool.
