Surface integrity analysis of grinding on ductile iron

摘要: Ductile iron (DI) is a widely used material and one of the most largely casts produced. Advances in understanding characteristics behavior this have led to development parts with dimensions shapes close final ones, components different thickness sections, including thin wall. When certain tolerances shape dimension be met, an appropriate machining process such as grinding must chosen. This type produces high local efforts hence great amount heat contact zone. Nowadays, there scarce information on effects surface integrity DI. A comparative study finish DI microstructures nodule counts (NC) under conditions was performed. All ground surfaces exhibited good finish, their roughness within expected range for operations. Microstructure alterations well strains were studied related hardness alterations. The role played by mechanical thermal residual stress profiles analyzed. clear relationship between distortion formation during established.
