Routing

Routing produces a better edge than saw cutting. Router bits may consist of one to four flutes; single- and double-fluted bits are commonly used. A bit whose cutting diameter equals the shaft diameter produces the best routing results. The length of the cutting edge should not exceed three times the diameter of the tool.

Recommended speeds fall between 18,000 to 28,000 rpm. The higher rpm rate allows faster feed rates and a smoother finish. For maximum production, operate at a feed rate just below the chipping speed.

Vibration during routing needs to be minimized. Use clamping if possible. Even small vibrations can cause crazing and fractures in acrylic sheet.

Proper feed direction is essential for a smooth cut. Feed the router counterclockwise for external cuts; clockwise for inside edges.
