2019-6-18 · Centripetal and Centrifugal Force are the action-reaction force pair associated with circular motion. Centripetal Acceleration. Velocity is a vector - specifying how fast or slow a distance is covered and the direction of the movement. Since the velocity vector the direction of a body changes when moved in a circle - there is an acceleration.
Milling is the most common form of machining a material removal process which can create a variety of features on a part by cutting away the unwanted material. The milling process requires a milling machine workpiece fixture and cutter. The workpiece is a piece of pre-shaped material that is secured to the fixture which itself is attached.
