  • For the sake of evaluating the effect of laser processing parameters on the shaping accuracy of laser freeform fabricating for solid metallic parts;the experiment was arranged by means of orthogonal design.With the aid of CNC continuous interpolation model endowed with velocity prospecting,the problem of too large laser heat input on the sectional contour-path during fabricating of thin-wall metallic sample was solved.The metallic samples which in good shape were fabricated by means of laser freeform fabrication.The result shows that transverse velocity and laser power were the two major factors affecting the shaping accuracy and the effect of the former was more remarkable.
