Abstract

The wear produced by free-pinned tools is difficult calculate, since their angular movement is not entirely predictable. First, we analyze the wear produced with free-pinned ring tools using both simulations and experiments. We conclude that the wear of an incomplete ring is directly proportional to its angular size, independently from the mean radius of the ring. Second, we present an algorithm for the calculation of the wear produced by free-pinned petal tools, since they can be considered as a linear combination of incomplete free-pinned ring tools. Finally, we apply this result to the enhancement of a defective flat surface and to aspherate a concave spherical surface.
