Elliptical Vibration Assisted Machining with Single

Optical quality surfaces on non-ferrous materials are commonly produced with single crystal diamond tools and precision turning machines. To add ferrous and brittle materials to the list of diamond turnable materials, a process know as elliptical vibration assisted machining (EVAM) has been developed.

How to Reduce the Effect of Vibration in Production Grinding

Sep 01, 2018 In a production-grinding operation, waviness on the part surface is a potential clue that the machine or process has developed a vibration problem. The effect might be seen in inspection, or if there is a lapping or polishing step, more time might be spent during that step removing the waves.

Measuring Vibration with Accelerometers NI

Jul 15, 2020 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

Whole-body vibration: An effective workout? Mayo Clinic

Whole-body vibration can offer some fitness and health benefits, but it's not clear if it's as good for you as regular exercise. With whole-body vibration, you stand, sit or lie on a machine with a vibrating platform. As the machine vibrates, it transmits energy to your body, forcing your muscles to contract and relax dozens of times each second.
