The article deals with the possibility of additional devices in closed die forging technology using mechanical presses. The main purpose of the additional equipment should be increasing of the productivity. Way to increase productivity may be appropriate connection of the press with a device for material preforming. The article presents ways of preforming with usage of forging rolls and cross wedge rolling. The output is a comparison of both methods on the example of preform and evaluation of the advantages and disadvantages of the individual methods. Both methods of preforming are analyzed using finite element method simulations.

The article is aimed at verifying the state of a real workplace using virtual reality. In analyzing the readiness of virtual reality applications, augmented reality was selected for the following work. The most significant advantage of augmented reality is the implementation of a virtual model and the ability to deal with the analysis in a real environment, which is particularly beneficial in the case of production plants. In the first phase of the work, an analysis of the current state of the workplace was carried out, where the requirements for the design of the new workplace were specified. This was followed by the phase of design preparation in 3D modeller. At this very stage it appeared to be advantageous to use virtual reality applications; in the design process, regular approval procedures are required as for an expert team (management, design, quality, ...), which puts high qualification requirements on the readiness of this team. In this phase, the 3D design of the new workplace was inserted into the application supported by augmented reality and some options were indicated to deal with the ergonomic and risk analysis. The result of this work is, in particular, an extension of options in designing and analyzing production workplaces and machinery in multidisciplinary teams.
