Ball end milling process is one of the most widely used end milling process, which is used for creating intricate shapes, contour and generating 3D shapes on the workpiece. It is extensively used in automobile, aerospace and die/Mold industries. Tool wear is one of the most important criteria which directly affects the cutting forces, surface roughness, dimensional accuracy and machine tool health condition. Thus, it is of paramount importance to accurately predict the tool wear in ball end milling process. In the present research, tool wear in ball end milling of Ti6Al4V has been determined using the three cutting factors such as rotational speed, feed and axial depth of cut. A four flute ball end milling has been used for the experiments and wear behavior of all the four flutes have been analyzed in terms of machining time. From the results, it has been observed that the wear is more on the cutting flue number 1 which is also the first flute which first engages with the workpiece. Wear was also found equivalent to the first flute on flute 4. The wear on the second and third flutes was relatively small.
