Geometric, kinematical and thermal analyses of non-round cylindrical grinding

摘要: Abstract This paper is concerned with the analyses of grinding geometry and kinematics in zone develops a thermal model, along chip-thickness-dependent value specific energy into workpiece. The are modeled for arbitrary non-round workpiece forms. Unlike other models, which based on fixed, constant geometry, model presented here first principles using fundamental, transient, non-constant thus constitutes much-needed advancement technology. A novel experimental approach also taken, uses workpiece, rather than total coupled an estimate partition, previously has proven difficult to achieve accurately. verified work predicted temperatures reasonable agreement associated onset damage, determined via metallographic examination Barkhausen noise. Finally, some challenges noise evaluate damage investigated, namely differing response characteristics stressed overtempered material vs. rehardened material, how these can be overcome practice.
