The elements characterizing the forced

In nonlinear systems, the first order of smallness terms of quadratic nonlinearity and the forced excitation with nonresonance frequency and the second order of smallness terms of linear friction, cubic nonlinearity, forced and parametric excitation with resonance frequencies have no effect on the oscillation in the first approximation.

In nonlinear systems, the first order of smallness terms of nonresonance forced and parametric excitations have no effect on the oscillation in the first approximation. However, they do interact one with another in the second approximation.

This chapter presents basic knowledge on the special kind of the machining process in which a workpiece material hardened to 45–70 HRC hardness or more is machined with mixed ceramic or CBN tools. An extended comparison with finish grinding, as well with other abrasive finishing processes, is carried out. Specific cutting characteristics, including cutting forces, chip formation mechanisms and tool wear modes with relevant interface temperatures are discussed in terms of process conditions. Currently developing finite element (FE) and analytical modelling is overviewed.
