CALCULATION OF THE TEMPERATURE DISTRIBUTION IN DIELESS DRAWING

Dieless drawing is an example of flexible metal forming processes. The investigation of the main process parameters and their interdependenc e is the prerequisite for the deliberate choice of input parameters to get the desired quality of the workpiece. Drawing force, drawing velo city, and temperature are the main control parameters. But only the te mperature can be influenced locally whereas the force and the velocity can be adjusted only globally. Because of this special importance of the temperature analytical and numerical models for the temperature di stribution along the deformation zone have been developed.
