Effects of workpiece thermal properties on machining-induced residual stresses - thermal softening and conductivity

Workpiece material properties play a key role in controlling the cutting process, and consequently residual stresses. Different materials may behave totally differently under the same cutting conditions; they may produce different types of chip, surface finish, residual stress, etc. The current work examines the effects of two workpiece thermal properties, specifically thermal conductivity ( k) and thermal softening exponent ( m), on …
