Özet:
The problem of surface quality and cutting stability in the machining processes
is very important and is strictly connected with the final quality of the product.
Therefore, this paper describes a new theoretical model for the dynamic cutting forces
of orthogonal cutting in turning. A specific advantage for the presented model is the
convenience for vibration prediction. The presented dynamic force model is used to
predict variable cutting forces with dynamic cutting between cutting tool and
workpiece. This model is considered two degree of freedom complex dynamic model
of turning with orthogonal cutting system. The complex dynamic system consists of
dynamic cutting system force model which is based on the shear angle (φ) oscillations
and the penetration forces which are caused by the tool flank contact with the wavy
surface.
