Machine Stiffness an overview ScienceDirect Topics. The grinding performance of a grinding machine can be greatly improved by increased machine stiffnessThe effect of stiffness in a real grinding situation can be shown by the stiffness factor K described in Chapter 2, where K is the ratio of real depth of cut to set depth of cut A low stiffness factor reflects high grinding forces and low ...

Most machine tools are lightly damped. Machine stiffness and damping vary according to the vibration mode. The impulsive response shown in Fig. 12.1 is typical for a lightly damped machine. For a spring-mass-damper system, motion is described by, where x is deflection and F is the applied excitation force.The equation of motion states that the applied force is reacted by the elastic, damping ...
