Abstract: A large amount of material is removed during the milling of a water chamber head manufactured of high-strength 508III steel. The performance and service life of coated cemented carbide inserts have significant influences on processing efficiency and the quality of nuclear power components. This study will conduct single-factor milling experiments of water chamber heads relevant to practical working conditions. Influences of different milling parameters on the insert failure behaviour are analysed based on experimental results and simulation data. The failure mechanism of insert wear and fracture was also discussed. Finally, the influences of coating types and thickness values on the wear behaviour of cemented carbide insert while cutting 508III steel were investigated. The results of this research can be implemented in the improvement of coated cemented carbide inserts in regards to failure resistance and service life.
