The femtosecond laser “cooling” polishing method was proposed for processing of metallic honeycomb core under air atmosphere. The polishing process parameters were optimized by the two sliding-level method
and process window prediction model of GH4099 sheet was determined firstly. The set of optimal process parameters for least surface roughness combined with processing efficiency is an off-focus distance of 0.2mm
a laser powder of 0.3W
a scanning space of 10μm
and a scanning speed of 2.3m/s. Under this condition
the surface roughness of GH4099 honeycomb core specimen decreased by 65%
and the polishing efficiency is 1.2h/(210mm×210mm).
