The styrofoam is used well for the model material of the Evaporative Pattern Casting Process. However, the styrofoam is difficult to cut, because it is soft and low-intensity. It is found that the styrofoam is easy to cut with the cutter knife on large rake angle and large inclination angle. In this paper, experiments to obtain a basic data of plane cutting are carried out with round blade. As a result, it has been found that the good surface can be obtained with 45°or more rake angle and 70°or more inclination angle. Furthermore, the prototype rotary cutter is made and examinations are carried out.
