The main point of this paper is simulation focused on passive safety of manufacturing systems. The passive safety of manufacturing system is connected with smaller safety risk compared with another fields of industry (e.g. automotive passive safety, rail vehicles passive safety or terminal ballistics protection). The revolutions of manufacturing system could reach 10000 [rpm]. The tangential speed on the larger diameter of a manufacturing tool can be sometimes higher than a speed of rifle bullet. The safety risk during an accident is significant. The parts could exceed the safety barrier and they can cause fatal injury to the staff. The simulations, presented in this paper, are aimed to the problem of terminal ballistic where the experiment is complicated. The paper summarizes the findings from the field of injuries caused by machine tools. Statistics of injuries are described here as a possible starting point for determining the frequency of occurrence. As an interesting point of research is described evaluation of the safety risk caused by released machine parts. The two possible ways for numerical simulations are shown in this paper. The first approach is the FE (finite elements) simulation. The second approach is SPH (smooth particle hydrodynamics) methodology. The advantages, disadvantages and applications of these methods are described at the end of the paper. The conclusions could represent the first step in simulations for safer structural design of machines.
