Ball-end milling is widely used in five-axis high-speed machining. The abrupt change of tool orientations or rotary axes movements will scrap the workpiece. This research presents a smoothing method of rotary axes movements within the feasible domains of the rotary-axes space.
In many milling operations the cutting tool must step over and make several adjacent cuts to complete machining a feature. As a result a small cusp of material called a scallop will remain between these cuts on any surrounding walls or on the machined surface if a ball end mill is used.

Ball milling motion has been previously studied through computationally expensive off-line experimental video processing and numerical simulations by the discrete element method. This research establishes a more efficient formulation of the ball energetics and kinetics similar to the Brownian kinetic theory of statistical mechanics.

2013-9-29 · a complex machining process like five-axis ball-end milling. Most of the models developed in the literatures consider three-axis ball-end milling. Besides cutting force has been considered as a vector that is applied on tip of the tool rather than take it as distributed load acting on cutting edge.
The agreement between the results indicates that the model can accurately calculate the CWE boundaries in the ball-end milling of all inclined convex concave and saddle surfaces. Good performance of the model is also demonstrated by comparing the computation time of the model with that of the z-map method. Finally parametric studies are.
