Experimental Study of Effects of Machining Parameters on Cast Iron by Slot Milling Operation

Precision machining processes like milling are crucial for achieving close tolerances in machine tool design. While several processes contribute, T-slot milling, utilizing rotating cutters to remove excess material, remains a prevalent technique. However, high cutting forces and limited stability often restrict productivity. This study investigates the influence of key machining parameters on T-slot milling performance. The design of experiments facilitated the execution of a comprehensive study, enabling the generation of empirical models via regression analysis. Response surface plots were employed to visualize the impact of individual and combined parameter effects. Statistical analysis using ANOVA further elucidated each parameter's significance and interactions. The developed models provide valuable insights for optimizing T-slot milling conditions, fostering improved productivity and material removal rates within the constraints of stability and process limitations.
