Intermittent motion mechanisms are widely used in semiautomatic and automatic machinery. Currently, the most common are mechanisms with a one-way coupling or mechanisms of variable structure. The intermittent movement in these mechanisms is provided by breaking the kinematic chain, so their use is undesirable in high-speed machines. The paper presents and analyzes kinematics of planetary ...

Difference Between Kinetics and Kinematics. Kinetics and kinematics are branches in physics that deal with the motion of an object. Although both the terms sound similar, there are a few differences between them. Kinematics desrcibes motion using equations of motion. Kinetics explains how a body responds when a force or torque is applied to it.

The KSF-team developed an innovative system with a new kinematic for internal cylindrical machining, based on the following aims: • The grinding forces should not cause elastic deformation of the spindle. • Internal cylindrical grinding should be possible with higher metal removal rate. • Thermal damage should be reduced.

Actuation of Machines. A machine is an integration of different mechanisms designed and assembled such that they can perform required work. The linkages and mechanisms inside the machine transfer the input mechanical work from the input point or generating site to the point where a useful effect is produced.
