| Abstract | ||
| In this work the methodology to evaluation the abrasive wear in closed warm forging die blocks material were manufactured from hot work tool steel H13 in two conditions; unquenched and quenched and tempered (QT).Two hundred flat countersunk head rivet are produced by warm forging operation, 100 forging (rivet) in each die block material. The wear in die is evaluated by implementing a methodology of measuring the used (worn) dies profile by a coordinate measurement machine CMM, then compensate the predicted plastic deformation die surface by using FEM-simulation code DEFORMTM-2D to separate the captured wear depth in die surface profile. The measured (separated) wear depth is used in Archad’s wear model to estimate the experimental wear coefficient (K) in order to comparing it with the predicted (numerical) wear coefficient (K) from simulation of forging operation. The suggestion of a new wear coefficient (K) to optimizing the forging process, gives the designer a possibility of forecasting the reached wear level. The numerical results showed a good agreement with experimental where the maximum differences are (12 % and 12.6 %) for unquenched and quenched and tempered die material respectively. | ||
