Abstract

The laser- assisted turning experiments for 9CrSi hardened steel (62 HRC) were set up by using the YAG laser source. A full factorial experiment was designed with 9 trials to analyze the influences of the laser power, cutting speed and feed rate on the surface roughness. The cutting tool used for this work is the TiAlN coated carbide insert. The results indicated that the laser power and the feed rate are the greatest effect parameters on the surface roughness and the cutting speed exhibits the lower influence on surface roughness in the laserassisted turning 9CrSi hardened steel process. In this study, a mathematical function was also determined to present the influence of the laser power, cutting speed and feed rate on the surface roughness in the laser-assisted turning 9CrSi hardened steel process. The minimum surface roughness in laser-assisted turning process can be obtained by setting the laser power (A), feed rate (C) and the cutting speed (B) with high, low, and low levels respectively
