Micro surface textures have various applications, such as friction/wear reduction and bacteria sterilization. Deformation-based micro surface texturing has the potential of economically creating micro surface textures over a large surface area. A novel desktop micro surface texturing system is proposed for efficiently and economically fabricating micro channels on the surface of thin sheet material for micro fluid and friction/wear reduction applications. Both experimental and numerical studies were employed to analyze the problems of the flatness of the textured sheet, the uniform of the channel depth and pile-ups built up during the micro surface texturing process. The results demonstrated a clear relationship between relative velocity of the upper and lower rolls and the flatness of the textured sheet and the final profile of the micro channels.
