The criterion for selecting the right cutting technique for a specific application is not limited to the intended cutting speed and material thickness, but it is also related to the material's physico-mechanical properties. In other words, the large number of composite features necessitates an individual approach to determine the likelihood of cutting a composite material with a specific method. Although it is well known that plasma cutting is not commonly used in cutting composites, the authors took into account this type of cutting therapy. The paper discusses the phenomena that have a direct influence on the surface quality of the produced surface and the formation of the most common defects encountered. For each cutting technique, the paper discusses the phenomena that have a direct effect on both the quality of the resulting surface and the emergence of the most common defects.

Computer simulation has successfully managed the executive components of the CNC machines's development trajectories today. The changes in the cutting system properties along the route routes are not taken into account in this case. These shifts can be made a priori as a result of the energy released in the cutting zone and then delivered to the machine controls as a result of the changes. This paper introduces a new approach to the numerical simulation of a controlled dynamic cutting machine, whose behavior changes as a result of lower forces operating in the interface between the tool and machining zone due to the aforementioned introduction of parameter changes of interacting subsystems and the effect of reducing forces acting in the interface between the tool and machining zone. The CNC system with the variable process properties matches regularly, according to it, making it possible to increase processing quality while still ensuring the consistent quality of the batch production of parts.
