An Experimental Investigation of the Effects of Fiber Laser Percussion Drilling: Influence of Process Parameters

摘要: This study is focused on investigating the parameters of laser percussion drilling process nickel-base super alloy Inconel 718 with thickness 1 mm. Fiber power 500 watts was used as source. Laser pulse frequency, duty cycle, power, focal point position, were assumed variables. The hole geometry features, i.e. entrance diameter, circularity hole, and taper measured. results indicated that frequency has a direct influence diameter. Increasing cycle leads to increases in taper. By increasing diameter increases.
