Description
図4(a)~(d)は、レーザ加工装置1における加工終了検出処理を説明するための図である。図4(a)~(d)は、送り機構がレーザ光2を被加工材20に切り込む方向(近づける方向)に移動させる様子を示すが、送り機構が被加工材20をレーザ光2に近づける方向に移動させてもよい。ここでは送り方向をx軸正方向とし、送り速度vを一定とする。
Ith=α×I0
で求められる。ここでαは、被加工材20の材料とレーザ光2の諸元、被加工材20に対するレーザ光2の切込み量に依存して設定され、0.8以上、1未満の値であって、たとえば0.93~0.97の範囲内の値に設定されてよい。
Ith=α×I0
で求められる。αは、被加工材20の材料とレーザ光2の諸元、被加工材20に対するレーザ光2の切込み量に依存して設定され、0.8以上、1未満の値であって、たとえば0.93~0.97の範囲内の値に設定されてよい。
たとえば4回目の検出結果36において、加工位置S2から加工位置S3までの定常加工範囲内で検出される光強度が所定の閾値Ith以上になると、制御部13は、5回目の加工送りを実施することなく、加工の終了を検出してもよい。

受光したレーザ光の強度を検出する強度検出部と、
検出した光強度の変化にもとづいて、加工が終了したことを検出する制御部と、を備え、
前記制御部は、検出した光強度が増加しなくなると、加工が終了したことを検出する、
ことを特徴とする加工装置。 - 前記送り機構が、被加工材をレーザ光の筒状加工領域に対して、所定の加工軌跡で複数回相対移動させて、被加工材を加工するとき、前記制御部は、前回の加工時に検出した各加工位置における光強度と、今回の加工時に検出した各加工位置における光強度とが等しくなると、加工が終了したことを検出する、
ことを特徴とする請求項1に記載の加工装置。 - 前記送り機構が、被加工材をレーザ光の筒状加工領域に対して、所定の加工軌跡で1回相対移動させて、被加工材を加工するとき、前記制御部は、各加工位置における光強度が所定の閾値Ith以上であることを条件に、前記送り機構を制御して、被加工材をレーザ光の筒状加工領域に対して相対移動させる、
ことを特徴とする請求項1に記載の加工装置。 - 前記制御部は、レーザ光による加工中に前記強度検出部が検出した光強度が所定の閾値Ith以上になると、加工が終了したことを検出し、
閾値Ithは、レーザ光が被加工材を照射しないときに前記強度検出部が検出した光強度I0に1未満の値αを乗算して求められる、
ことを特徴とする請求項1から3のいずれかに記載の加工装置。 - レーザ光の集束箇所を含む筒状加工領域を走査して、被加工材を加工する加工装置において、加工が終了したことを検出する方法であって、
