Effects of surface profile smoothing in laser multi-pass dieless drawing process are studied experimentally to fabricate microtube of stainless steel. In the experiment, material is SUS304 tube with outer diameter of φ500μm and thickness of 130μm. To investigate the effects of surface profile smoothing, drawing limit and distribution of outer diameter in each pass are measured. As a result, it is found that drawing limit increases by surface profile smoothing, and variation of outer diameter increases as the number of drawing increases. Consequently, it is found that removing the variation of outer diameter reduces the risk of fracture in multi-pass dieless drawing process.
