2008-3-24Simulation of ball end tools milling by N. Vidakis1 A. Antoniadis2, C. Savakis3 and P. Gotsis4 Abstract Milling by ball end tools is extensively used for finishing of complex surfaces. The topomorphy of the resulting surface is a research assignment of great interest for many years, whereas various models have been proposed in this area.
In order to predict tool deflection more accurately, this paper presents a special three segments cantilever beam model for ball-end tool deflection in sculptured surface milling. Different from the traditional two segments cantilever beam method, the ball-end tool is divided into the shank, the flute and the ball-end parts in this new model.
Model of geometry and tilt tool milling process is established. A double helix micro-flute ball end mill made of cemented carbide is used in the groove milling tests with radius 0.5mm at a helix angle of 30. The rotational axis of the tool is inclined to improve the surface finish.
