Within the software, fluid cutterpaths ensure the best possible surface finish, for example, trochoidal movements which favor climb milling optimize cutting conditions and minimize tool load - ideal for tough materials. The result is much less risk of tool breakage, longer tool life and lower stress on the component. For aerospace components these factors are particularly important, as tool failure can seriously damage the part, while excessive machining forces can be deleterious to the material structure, which may affect the performance of the finished part.
