Some old notes on this:

  • Number of Passes — Size guidelines for adding a radius at the tip (may vary based on bit angle and material):

    • <10mm — one pass

    • 10–20mm — ~0.5mm

    • 20–35mm — ~0.75mm

    • >35mm — 1mm radius

    • The tradeoff is feature size vs. feature depth — an acute angle allows one to cut a smaller, finer feature w/ more depth, while a more obtuse angle allows one to cut a larger area w/ a single pass and while having a single bottom, as opposed to a ragged set of scallops.

      • Recommended bit angle for a given text size:
        • <1" 45–60°
        • 1–2" 60°
        • 2–4" 60–90°
        • 4–6" 90°
        • 6–10" 90 to 120°
        • >than 10" 120° or greater

    • Material guidelines:

      • hardest timber available
      • use conservative plunge and feedrates even when doing more than one pass
      • avoid overlapping V-cuts — tends to cause splintering at the top edge, leave a ~0.5–1mm gap at the top
      • use a cutter w/ centered/symmetrical geometry

    • Formula for calculating the effective diameter of a V-bit at a given depth in Excel this is:

      =TAN(RADIANS(B3)) * B4 * 2

Where B3 is the angle in degrees and B4 is the depth in inches
