Grindability of some metallic and ceramic materials in CFG regimes

摘要: Abstract Creep-feed grinding (CFG) is characterized by large wheel depths of cut and low table speeds a process most suitable for geometrical shaping. It also improves the productivity surface quality various engineering components with complex profiles. In last few decades, application CFG to metallic materials has been quite successful, but many problems have encountered in creep-feed ceramics as this kind material exhibits very different micro- macro-behavior. For example, one main integrity micro-cracks induced sub-surface ground ceramic components, which usually does not take place because their ductility. Accordingly, manufacturing industries need imperatively practica guidelines meet technological requirements production. The purpose paper investigate grindability some through set carefully arranged experiments. Wheel depth speed are two processing variables obtaining specific removal rates. A high carbon chromium bearing steel chosen be representative materials, normally sintered SiC Si3N4 ceramics. Discussion focused on relationships variation forces, roughness interface deformation mechanisms. New formulate modelling forces successfully proposed. series in-depth understanding useful results investigations types provided. simple obtained would practical design industrial operations.
