Laser ablating and chemical eroding combined technique is applied to some typical kinds of high alloy steel experimental machining. How the laser energy density, repetition rate, pulse width, scan velocity and other parameters affect the surface quality of material simple dipped in different corrosive liquids is studied and analyzed mainly. The relations between dimensional precision and those parameters are also investigated. Then internal causes of those relations are discussed. Experiments show that following: 1, Chemical eroding reduces the slag on the laser ablating samples and surface roughness; 2, Laser energy density, repetition rate, pulse width, scan velocity and other parameters signify the quality of machining surface.
