Prompt
Overall envelope (keep this fixed) Bounding box: 50 × 50 × 200 mm (W × D × H), including base, tiers and top cap. Target capacity example: 4 tiers × 12 positions = 48 bits (adjust per chamber). 3) Architecture Hollow central column (Ø12–16 mm ID) with 4–6 thin ribs (2–3 mm thick) tying into square tier plates. Reduces mass and speeds pump-down. Square tier plates (one per layer), 3–4 mm thick, with perimeter “branch” cups. Spacers between tiers (hollow tubes), sized to meet vertical pitch (see §5). Top cap to lock the stack; hub/arbor interface at the column base (see §7). 4) Branch/cup geometry (the part that holds each bit) Two workable approaches—pick A (best) or B: A) Direct-fit cups by shank size (recommended) Cup ID = shank Ø + 0.20–0.30 mm clearance (smooth load/unload). Wall thickness: 1.5–2.0 mm (minimum), vent hole at cup bottom Ø2–3 mm. Branch OD: Cup ID + 3–4 mm (gives the wall thickness above). Entry chamfer: 0.5 × 45° (or R0.5) at the lip. B) “Universal” 15 mm cups + removable sleeves Fixed Cup ID = 15.0 mm (legacy you mentioned: 7.5 mm radius). Sleeves adapt to actual shank sizes (e.g., 6, 8, 10, 12 mm). Then set Branch OD ≥ 18–19 mm to keep ≥1.5–2.0 mm wall thickness. Note: Do not pair 15.0 mm ID cups with 11.0 mm branch OD—insufficient wall. 5) Angles, pitch, spacing (shadowing control) Outward branch tilt: 7–10° from vertical, pointing away from the column. Tier twist (rotational offset): 15–20° between consecutive tiers. Radial pitch (cup-to-cup along the perimeter): center-to-center spacing ≥ Cup OD + 1.0 mm. Vertical pitch (tier-to-tier): clear height between cups ≥ largest tool OD at flute (rule-of-thumb: Cup OD + 6–10 mm). Edge radii: R≥0.5 mm on all internal corners/transitions to reduce particle shedding.
