Machining and more specifically face milling are productive ways of material shaping. Predictive models are very important for effective: quick, easy-to-use and accurate process planning. There are many industrial and scientific researches about modelling the prominent process parameters of machining, notably the machining forces. The main cutting force is one of the most important indicators as it is a primary output parameter of the chip-removing process. The specific cutting force is long time used, traditional type of modelling the main cutting force but still there are missing or difficult-to-find numerical information about the effect of some of the input machining parameters such as cutting speed. In this research, the effects of the theoretical chip-section geometry and the cutting speed were examined through face milling experiments of the S960QL high strength structural steel.

Nowadays, there is a growing need for parts, which are made directly to final size because of the favorable cost of the production. However technologies that keep the high geometry accuracy and good mechanical properties are required such as moulding, forming or powder metallurgy. This is the reason, why these technologies are improved continuously. In the paper our research focused on the technology of the powder metallurgy is introduced. This paper gives a short survey about the mechanical properties of sintered metal components and their manufacturing technology. The goal of the introduced research is the improvement of the mechanical characteristics of the examined sintered metals by varying the process parameters, like material composition, compact density and sintering conditions. The authors explain the test methods, the experimental tests, and the results regarding the experiences.
