The procedure for building boundary deformation surfaces has been worked out as well as the method for the evaluation of metal plasticity under volumetric stress conditions. Processes, occurring in the hydraulic drive with proportional electrohydraulic pressure valve, have been investigated. The developed control algorithms provide the required parameter variation law for the plastic forming process. Product Description popup.authors popup.nrat_date 2020-04-02 Close
