Ultra precision blade edge processing method using femtosecond laser

摘要

The present invention relates toAn ultra precision blade edge processing method using femtosecond laserGrinding wheelThe first step of grinding the blade edgeThe step of secondary grinding at least a portion of the blade edge portion by irradiating the femtosecond laser along the longitudinal direction of the ground blade edge portion;The secondary grinding stage isOscillating the femtosecond laser andDeformation of the femtosecond laser energy distributionIncreasing the magnitude of the energy distribution of the femtosecond laser andThe central portion of the energy distribution of the femtosecond laserAt the end of the blade edge portion, andChange the direction of the femtosecond laser beamIrradiating the blade edge portion through the focusing lens andThe stage on which the blade is placedMove the blade in the longitudinal directionIt is characterized by the step of irradiating a femtosecond laser.Diagram
