We conducted scribing experiments with a diamond tipped indenter in the absence (dry) and in the presence of a water-based cutting fluid. This experimental study investigated the effect of laser parameters on the machining of SS41 and SUS304. The result of this research showed that the factors that influence the surface roughness level of carbon steel material are spindle speed followed by feed rate and depth of cut. 10 0 obj >> /S /Transparency An inverse effect where the cut is wider on the side of the nozzle and narrower on the other material side. This means that the material is less stressed per pass.
