摘要:Sheet metal with micro-groove on its surface has following advantages, such as lightweight, high wear resistance, and drag function, and is hence widely used in various applications. Currently, there are a series of methods to process micro-groove, but those methods are not used in mass production. In this article, roll-to-roll sheet forming method preheated to elevated temperatures has been discussed and shown to produce micro-structure with better shape and height, in addition to aiding the possibility of continuous production. The influence of rolling micro-groove is studied numerically using the software Deform-3D. Temperature, grain size, geometry, rolling load, size, and height of micro-grooves have been discussed. The results show that the temperatures, widths of the groove, and radius of top and bottom fillets have significant influence on the forming process. At the same time, the experiments prove the feasibility of heated rolling micro-groove on surface of sheet metal.
