Abstract

Orthogonal cutting tests of aluminum plates were carried out in such manners as repeated dry cutting, wet cutting, repeated wet cutting and combinations of them under different depths of cut, cutting speeds and rake angles to minimumize the residual stress. In the repeated cutting, the distribution of residual stress in the finally cut surface is considerably influenced by such a cutting condition that leads to high cutting resistance. Both wet and dry cutting result in the same patterns of stress distribution. A combination of dry rough cutting and wet finishing under the adequate cutting conditions ensures the cut surface free from residual stress.
