EXPERIMENTAL INVESTIGATION OF LASER-TEXTERUED ON ROLLER WITH MICRO-CONVEX TOPOGRAPHY

Abstract

Abstract: The mechanism analysis of micro-convex manufactured by larser-textured and experimental study on controlling of larser parameters are carried out, based on tribology design for reasonable surface topography on cold rolling steel sheet during punching. It is indicated that the micro-convex can be obtained when the import energy of laser is between 33～ 75 kW/cm2, the distance far from focus is +0.10～+0.15 mm, frequence of scan is 5 Hz, duration is 0.5 ms accompanying with powergain. This work laid foundation of study on the topography duplication during skin pass and on performance of cold rolling steel sheet with regular and smooth ding during punching.

Key words: Larser-textured, Micro-convex, Surface topography
