Abstract
Description
−フレームパラメタ、特に着用者が選んだフレームのリムの受け溝の幾何学的データ、特に受け溝の底をトレースした曲線及び必要に応じた受け溝の断面形状のフレームパラメタを取得する工程と、
−レンズそれぞれの心出する工程、すなわち、設計された意図である光学的機能を正確に機能するために着用者の目の瞳の前において正確に心出しされるようにフレームを占有するそれぞれのレンズの位置を測定する工程と、
−触覚器システムを使用し、トリミング後のその外形の幾何形状を特性化するそれぞれのレンズ面上の点座標を測定する工程と、それから、
−(半径複製機能と呼ばれる方式で)定値トリミング半径を作り出す工程であって、対応する受け溝(bezel)、確定した心出しパラメタ及び触覚器で測定されたレンズの座標から読み込まれた幾何学的なデータを確かめながら、トリミングされるレンズの外形の意図する空間位置を画定する定値トリミング半径を作り出す工程と、そして最後に、
−それぞれのレンズをトリミングする工程、すなわち、その外形を所要の形状に機械加工又は切削し、確定した定値トリミング半径を確かめ、必要に応じて機械加工の終わりに、面取り(bevelling)のために面取りグラインダーを使う、すなわち、レンズをフレームの受け溝で保持するためにレンズの面取りする工程と、を備える。
−受け溝の断面はフレームのそれぞれのリムのたった一点で測定されること、
−フレームはフルフレーム(closed frame)であること、
−フレームはハーフフレーム(semi-open frame)であること、
−フレームのこめかみ部の一点で測定された受け溝の断面形状はデータベースと比較されること、
−フレームは、ボウル上の受け溝ワイヤの変形か、又は3Dリム形成機械を使用した受け溝ワイヤの変形の結果であるか判定されること、
−フレームのこめかみ部の一点で測定された受け溝の形状は、フレーム周りの勾配の変化に関係するデータに関連すること、
を有してもよい。
完成したレンズの外形及び選んだメガネフレームに入れ子可能にするための外形に沿った面取り部の形状を含むトリムパラメタを算出する工程と、
を備える。
