Purpose: New laboratory equipped for modelling of technological processes. Methods of modelling. Design/methodology/approach: Laboratory equipped by two Silicon Graphic Indigo R 5000 stations, by one 500 an DEC OSF/1station and by Forge 2D and 3D, Hypermesh, Systus and Sysweld software systems was built up in the Department of Material Science and Technology at WBU Plzen. Findings: Some research programmes solving modeling of optimization of technological processes like simulation of cold deformation influence on the structure of P900 steel, or simulation of free forging of shafts manufactured from CrMo steel were carried out. Research limitations/implications: Partial results give a good agreement between experimental results and simulation methods. It is suitable to extent the experiments on further forged components. Practical implications: Results can be successfully used for efficient technology of components forging. Originality/value: Published results are original informations about contribution of modelling to specifying of technological parameters.
