two_point_depth — DRIVE pegsim op

• Data kinds: table → scalar

• Call: import fullseye as fs; fs.ledger.two_point_depth(kp, theta: 'float', model: 'str' = 'exact') -> 'float' (to call the implementation directly, import pegsim; pegsim.two_point_depth(kp, theta: 'float', model: 'str' = 'exact') -> 'float'; from the registry, opsdrive.get("two_point_depth"))

Usage

> This operator's description has not been translated yet. The original text follows as it is.

傾き θ [rad] で二点接触が始まる挿入深さ l₂ [m] (最狭部から先端中心まで)。3 つの模型を名前で選ぶ。

`"exact": 3-D の円柱で厳密 l₂ = (2R − r(cos θ + sec θ)) / tan θ(導出 (1′))。"small_angle"`: l₂ = 2c_r / sin θ

(OCW p.9 の l/d = c/θ を半径 clearance で書いたもの)。`"rectangle"`: 2-D の長方形近似 (D − d/cos θ)/tan θ(縁の点の

高さ r sin θ を無視するので θ = 6° で 0.5 mm 浅く出る —— 間違いの量を測るために残す)。

Raises `ValueError`: θ ≤ 0、θ ≥ θ_m_exact(入口にすら入らない)、未知の model。
