Research on cutting remanufacture deposited materials in the impactive condition

摘要

Orthogonal experimental were carried for cutting remanufacture deposited Materials in the impactive condition. By the experiments analysis, it can be known that the cutting capability of tools were determind by toughness of tools when the hardness of deposited materials is low. And the hardness of tools becomes the main roles for improving cutting capability when the hardness of deposited materials arrives to HRC56. At the same time, orthogonal design-direct analysis shows that the impact resistant capability of tools does not always means improvement in cutting capability. The comprehensive balance between strength of tools and impacts in the process is favorable method to improve cutting capability of tools.
