Özet

AISI P20+S steel is a sulfur-alloyed, pre-hardened plastic mold steel widely utilized in the plastic injection molding, tool making, and die-casting industries due to its pre-hardened structure and

mechanical strength. As a modified version of standard AISI P20 steel (industrially designated as DIN 1.2312), sulfur (S) is incorporated into this material to significantly enhance its machinability. Sulfur inclusion facilitates higher cutting speeds during machining, providing substantial time savings, particularly in the production of large and complex molds. However, during the dry machining process, this material generates significant heat at the cutting zone, which can negatively affect tool life and the surface roughness of the material. In this study, the effects of feed rate (0.2 and 0.4 mm/rev), depth of cut (0.3 and 0.6 mm), and cutting speed (50 and 120 m/min) on the cutting temperature during the dry turning of AISI P20+S steel were investigated using a 2^3 full factorial design, supported by ANOVA and Taguchi's Signal-to-Noise (S/N) ratio methodology based on the “Smaller is better” quality characteristic. Based on the experimental and statistical analyses, the most influencing parameter on cutting temperature was measured to be depth of cut. Sample 7 generated significantly higher temperature compared to other samples. Except Sample 7, the effect of cutting parameters on temperature was found to be limited. The temperature variation was less than 10% for all samples when all parameters were evaluated separately, indicating that the effect of cutting parameters on AISI P20+S steel is limited.
