In this work, both qualitative and quantitative analytical approaches were used to optimize the spiral contouring technique for complete continuous micromachining of targets. During laser ablation, spiral contours on the target were created by rotational and rastering motions (oscillation) in the x–y plane, while the laser beam position was fixed. Machining quality was characterized using laser to full surface interaction time and surface roughness. The results showed an increased laser–surface interaction time at a reduced raster angle and rastering velocity with high surface roughness at high machining time.
