Abstract
The paper details an experimental evaluation of workpiece surface roughness following slotting of hardened AISI D2 (~62HRC) high carbon, high chromium cold work tool steel (employed extensively in the mould and die industry) using 0.5mm diameter coated (TiAlN) tungsten carbide end mills. A full factorial experimental design was carried out to investigate the influence of variations in cutting speed, feed rate and depth of cut, each at 2 levels. Results were assessed using analysis of variance (ANOVA) while main effects plots and percentage contribution ratios (PCR) for the primary variable factors were calculated. The ANOVA suggested that cutting speed had the greatest influence on surface roughness (38% PCR) followed by feed rate and depth of cut at 24% and 18% respectively, all 3 parameters being statistically significant at the 5% level. Surface roughness (measured in the feed direction) was found to be a minimum when operating at 50 m/min cutting speed with a feed rate of 1 μm/tooth and depth of cut of 15 μm, and varied between 0.11 to ~0.15 μm Ra over a 520 mm cut length.
