Machined surfaces are judged to determine machining conditions. Quantitative parameters like surface roughness and sensory parameters, such as glossiness, cloudiness, sense of discomfort and so on, of the tester, are used as the criteria. Sensory par

It is necessary to increase the damping of a machine support structure (support damping) to reduce the residual vibrations caused by rocking vibration. The stiffness of the machine support system (support stiffness) is also an important parameter tha
