Calculation technique for cutting forces prediction in 5-axis ball end milling is worked out and realized as computational program. The curvilinear cutting edge is divided into small segments and the path for each segment is defined.
What is a force Everything on Earth is powered by forces pushes and pulls which act on our bodies and the things around us.. Forces make things move and stop moving. Some of the forces we are subject to are gravity (which keeps us on the Earth s surface) the centripetal force (the force that makes things move in circles) and friction (the force
