A recent trend in sheet-metal forming is to provide a specially-textured surface finish that develops small pockets to aid lubricant entrainment. Perform a literature search on this technology, and prepare a brief technical paper on this topic.
This is a valuable assignment, as it encourages the student to conduct a literature review.
This is a topic where significant research has been done, and a number of surface textures
are available. A good starting point is to obtain the following paper:
Hector, L.G., and Sheu, S., “Focused energy beam work roll surface texturing science and
technology,” J. Mat. Proc. & Mfg. Sci., v. 2, 1993, pp. 63-117.
