Current approaches to the analysis of metal shaping. It is pointed out that at the current stage it is necessary to design processes ensuring a specified material structure and an essential reserve of plasticity. Particular consideration is given to the problem of manufacturing products of powder and incompact materials. The approaches to the problem solution of metal stamping having anisotropic stress-strain properties are widely covered. It is offered to use methods of experiment planning for processing the results of computational modeling. It is offered to include random characteristics into a solution which could change at new metal lot obtaining. It is shown that changes in geometry, techniques and stress-strain properties can result in the considerable changes of values during metal shaping.
