Cutters Used:

Roughing – 1” Ball End mill, 4-Flute, Carbide
Finishing – 5/8” Ball End Mill, 2-Flute Carbide

Depth:

Roughing – varied from 1/4” to 2-1/2” deep with a 40% stepover
Finishing – 1/8” deep leaving 0.002” scallop height

These machining parameters are represented as starting points. Cutter type and material, spindle speed, feed rate, machine power and rigidity all affect machining results. User must determine best parameters for specific applications.

Tips:
- To saw dense boards (over 0.8g/cc) use a saw with offset carbide teeth to reduce binding
- Eliminate dust by lowering spindle speed and increasing feed rate
- Eliminate burning with sharp cutters and lower spindle speeds.
- Clear chips to prevent cutter heat build-up.
