Effects of Number of Inserts and Insert Materials on Surface Roughness of Cast-Iron Work Produced by Face Milling
In this work, the effects of two key factors of face milling including the number of inserts and insert material on surface roughness of cast-iron turbine housing work were systematically studied using full factorial designed experiments. Three insert materials including uncoated cemented carbide (TH10), commercial TiAlN/TiN coated cemented carbide (AH120) and tungsten carbo-nitride (WCN) coated cemented carbide were selected while the number of inserts was varied from 1 to 3 in this study. The results showed that both factors were statistically significant and the optimal parameters that yielded minimum Ra-value of 0.495 μm were the commercial TiAlN/TiN coated cemented carbide material (AH120) and three inserts.
