The objective of this work is to study the influence of the initial surface texture on the surface roughness and spatial frequency content of S7 tool steel after pulsed laser micro polishing (PLµP). PLµP is a non-contact surface finishing process that has been shown to effectively polish metal alloys. However, how the different initial surface textures of S7 tool steel will influence the extent of surface roughness reduction and the change of spatial frequency content has not been previously studied. This paper will present three different initial surface textures on S7 tool steel, produced by different manufacturing processes, and investigate the efficacy of PLµP at altering the surface roughness and spatial frequency contents.
