Hog-Out Optimization

Intended to answer: for a given material and tool/stepover/depth combination, how does feedrate affect accuracy (deflection), and how high a feedrate is possible? Knowing the behavior at high speeds allows a more informed choice of speeds without wasting material.

The test first prepares a "top-hat" shape at low speed (slotting cut + finishing pass), then cuts through it at progressively higher speeds. Deflection due to cutting load can be measured directly. Higher speeds produce higher loads and higher deflection.

Recommended starting values for wood with 1/8" bit:

  • Z height of cut: −1 mm
  • Z clearance: 0.5 mm
  • Rapid feedrate: 2000 mm/min
  • Raise/lower feedrate: 180 mm/min
  • Cutting feedrate: 900 mm/min
  • Slotting feedrate (slow): 300 mm/min
  • Stepover: 1.5 mm
