Abstract
Description
1)フィラメント形成(filamentation)を用いる切削/穿孔:フィラメントの形成はプロセスに起因して不均一に起こる:初めの高エネルギー密度に起因して、フィラメントを生成するレーザービームの入射側では、ワークのより深い後続のプラズマスポットに比べて比較的大きいプラズマ体積が着火し、すなわち、ワークの損傷溝(形成されるフィラメントに対応する)はテーパー状になる。このように、引き起こされる損傷(微小亀裂)は、レーザービームの入射側において出射側よりも一層強大になる。指向性強度試験(4点曲げ試験等)によると、0.7mmのガラス厚さでも縁強度の著しい差が明らかである。
2)プラズマ生成スポットの空間幾何形状:自己収束によって生じるプラズマ生成スポットは、球対称のエネルギー分布を伴う略球対称形状である。この形状は、プラズマ体積の周囲に方向とは無関係にランダム分布した微小亀裂をもたらす。結果として、亀裂は後の破断縁に突出し、強度減少作用を有する。
3)自発的な破断:脆い材料のフィラメント形成中、内在応力によって、ワークの制御されない自発的な破断がプロセス中に起こり、結果として廃棄率が増加する。さらに、自発的な破断はワークの位置の変化をもたらし、それにより、自動加工が妨げられるか又は更には不可能になる。
