- 選定された粒径の砥粒が適宜のボンド材によって結合された切り刃を有する切削ブレードの検査方法であって、
被加工物をチャックテーブルで保持する保持ステップと、
第1の方向に回転軸を有するスピンドルの先端に切削ブレードを装着する装着ステップと、
該チャックテーブルと高速回転する該切削ブレードとを該第1の方向と直交する第2の方向に相対的に移動して、被加工物に複数の切削溝を形成する切削ステップと、
被加工物に形成された該切削溝を撮像手段で撮像して該切削溝の状態を検査する検査ステップと、を備え、
該検査ステップにおいて、単位長さ当たりの該切削溝の両側に形成された欠けの大きさ、欠けの数、欠けの面積の何れかの要素によって該選定された粒径が適正な粒径であるか否かを検査し、
該検査ステップは、該切削ステップの途中の該被加工物の切削を開始してから1〜10本目の該切削溝を形成する切り始めの間に実施することを特徴とする切削ブレードの検査方法。 - 該検査ステップでは、測定される該欠けの大きさと該欠けの数の分布を求め、判定基準となる標準偏差を閾値として該分布の標準偏差から該選定された粒径が適正な粒径であるか否かを判定することを特徴とする請求項1記載の切削ブレードの検査方法。
