"Opposed dies shearing process" is based on the idea of smooth surface formation by cutting mechanism and can be applied to brittle materials in principle. This feature is considered to be available for finishing of cast products and new demand for this process is expected. In this paper, precision shearing of cast materials by "Opposed dies shearing process" was studied. Four kinds of cast iron and cast aluminum under practical use were tested and unique characteristics in applying this process to brittle materials were cleared. Influences of working conditions on sheared surface were investigated and optimum conditions to obtain fracture-free sheared surface were given for each material. In comparison with other shearing processes, it was cleared that the sheared surface quality of this process was much better than that of conventional shearing process and almost equal to that of shaving process.
