Measuring Vibration with Accelerometers - .

14.03.2019 · Vibration is the movement or mechanical oscillation about an equilibrium position of a machine or component. It can be periodic, such as the motion of a pendulum, or random, such as the movement of a tire on a gravel road. Vibration can be expressed in metric units (m/s 2) or units of gravitational constant "g," where 1 g = 9.81 m/s 2. An object can vibrate in two ways: free vibration .

Development of a vibration device for grinding with ...

The vibration amplitude was in the range of 0 to1.5mm. The risk of surface burning and tempering was reduced with increased vibration amplitude. Vibration with a frequency up to 400Hz was used and grinding of a hardened nickel alloy was carried out, resulting in reduced cracking and surface burning. A superposition of grinding kinematics

Effect of grinding forces on the vibration of .

The steady-state dynamics and vibration behavior of the grinding machine spindle is simulated by a five degree of freedom model. The results indicate that when grinding different materials using a grinding wheel with fixed wear flat area, different vibration behavior is noticed. As the grinding wheel flat area increases, the level of vibration increases for all the degrees of freedom, which ...

Tips of Vibration Analysis in Grinding Machines – .

Tips of vibration analysis in grinding machines. When precision dies grinding, it is very difficult to solve the problem of vibration of the grinding machine. Because the vibration of the machine tool directly affects the effect of the dies processing. For example, the surface finish is poor. If it is precision molding grinding such as plug-in connector molds or cutting grooves, it cannot be ...
