One of the proposals of Industry 4.0 is the integration of machines and operators through network connections and information management. One of the challenges that can be addressed following this approach is the management of knowledge in the industry or, in other words, the transmission of knowledge from the expert operators to the new ones. This work has been developed a system that combines Virtual Reality and Process Mining to allow this knowledge transmission in the particular case of assembly tasks. Virtual Reality allows to create work environments that reproduce the real ones and interact with them without detracting resources of other processes or facing the risks of working with real systems. Process Mining allows to acquire the knowledge of experts, store it in models and then transmit it to novices. The developed system has been tested by means of several examples of assemblies with Lego
