Cutting Speeds:

Material

Bit Options

Spindle Speed Settings
(Controlled in the shop)

feed rate (speed in the x-y plane)

plunge rate (speed in the z plane)

pass depth

special notes

Acrylic

upcut foam bits

170

1.2

1.2

.1 (using 1/4 upcut bit)


Foam

upcut foam bits

  • 1/4" for 2" cut depths or less
  • 3/8" for 3 1/2" cut depths or less

180-200

8

8

equal or less than cut length of bit (see bit graphic)

  • greater resolution comes with higher density foam (ie. pink foam)

Formaldehyde-free MDF

Up to 1.5" prelaminated

Cut faster with wood bits or deeper with foam bits

300

8 (wood bits)

6 (foam bits)

8 (wood bits)

6 (foam bits)

Up to 2x Diameter (wood bits)

1x Diameter (foam bits)


Plywood

straight cut wood bits

190-260

1-2

1-2

equal or less than half of diameter of bit (see bit graphic)

  • if material is smaller than 18" x 18", screw it down to a separate piece of plywood or MDF
  • plywood can be bought in many variations, and the settings need to be adjusted accordingly

Solid Wood

straight cut wood bits

190-260

1-2

1-2

equal or less than half of diameter of bit (see bit graphic)

  • always (doesn't matter the size) screw solid wood to a separate piece of plywood or MDF because it WILL warp during routing
      • solid wood can be bought in many variations, and the settings need to be adjusted accordingly
Aluminum1/16" Spiral Downcut Carbide3000.20.20.01"
  • Use tape to tape down sheet metal perimeter to bed to reduce air leakage and stabilize vacuum hold down.
  • MUST USE AIR COOLING SYSTEM!!! - Notes: Make sure bit extends at least 1.5" out of collet. Aim cold air nozzle at bit as close as possible to bit at ~45 to 60 degree down angle with center of flow centered on bit and about 0.25" above tip.
