Cutting force modelling with effects of cutting tool geometry and tool wear in milling of DIN C45 steel

Popis výsledku v původním jazyce

This paper focuses on mathematical modelling of the cutting force with tool wear effect for milling by milling heads. With regard to a small number of experiments with sufficient accuracy, universality, speed and applicability in practice, a mathematical model based on the specific cutting force and cutting area was created. The proposed mathematical model, in comparison with other models, is refined by more accurate calculation of the specific cutting force and cutting area. The calculation of the specific cutting force is more precise due to considering the influence of the cutting speed as well as due to more accurate calculation of the undeformed chip thickness and because of the implementation of the correction factor of the tool flank wear which has a significant impact on the cutting force. The calculation of the cutting area is performed by more accurate calculation of the chip width as well as undeformed chip thickness. The chip width and undeformed chip thickness is refined by considering the straight as well as the rounded part of the cutting edge. For the proposed mathematical model, material constants for the workpiece material made of DIN C45 steel were obtained.
