A Geometrical Simulation of Ball End Finish Milling Process and Its Application for the Prediction of Surface Topography
Sculptured surfaces are widely used in the die and mold industries. The finishing process of these surfaces is time consuming and expensive. Improvement on the process must be applied to reduce or even eliminate the burden of manual polishing. Therefore, it is practically of great importance to predict and further to control the products surface finish during the finish milling process. This paper presents a general simulation methodology based on a Zmap model of workpiece for predicting surface topographic features and roughness formed in the finish milling process. The adoption of the discretization concept of the tool and workpiece makes it possible to dynamically track the cutting tool-workpiece interaction with the tool movement. Also, the effects of the cutting tool run-out and wear can be incorporated into the developed model through modifying the tool center motion and the cutting-edge shape respectively. At last, Experiments are carried out to study the milling process and to verify the simulation results.
