The surface roughness is a decisive criterion for the quality of the machined surface. Many researchers are interested to study the effects of the machining parameters on the surface quality as: the cutting conditions, the machining strategies, the tool geometries and the machining errors. All these studies are developed for the stationary feed rate and neglected the cinematic effects caused by machine deceleration and acceleration when the tool trajectories change a direction. The objective of this research was to investigate the effect of the velocity changes on the surface roughness. A set of machining tests in high-speed end-milling of the 42CrMo4 material by a ball nose end-mill is made. For the same cutting conditions, the roughness is measured on three zones respectively the acceleration, the stationary and the deceleration zone. It was seen that the cinematic change causes a poor surface roughness.
