Abstract
⺠We apply ultrasonic vibration to nanosecond laser machining. ⺠Ultrasonic vibration improves surface finish of laser-machined area. ⺠On the surface, particle agglomeration is suppressed by enhancement of near-field cooling. ⺠Ultrasonic effect reduces accumulation of recast layer and is more effective in repetitive machining.
