Abstract

【課題】多刃エンドミルを用いてインペラー等の薄肉素材を高送りの加工を行う場合に発生する切屑の排出性を良好にする。 【解決手段】複数枚の切刃を備えた切刃部３と、工具軸Ｏ回りの回転方向に隣接する切刃間に形成された刃溝８を有する多刃エンドミル１において、切刃のすくい面を、工具軸Ｏ側からシャンク部２の外周側へかけて底刃６のすくい面６ａと、これに隣接し、底刃６のすくい面６ａと異なる面を形成するコーナＲ刃５のすくい面５ａと、これに隣接し、コーナＲ刃５のすくい面５ａと異なる面を形成する外周刃４のすくい面４ａから構成する。底刃６のすくい面６ａと、それに回転方向Ｒ前方側に隣接する底刃６の逃げ面６ｂとの間に、刃溝８に連続する空間を構成するギャッシュ７を形成し、底刃６のすくい面６ａにギャッシュ７を構成する一方の面を兼ねさせる。
