The purpose of this study is to develop a new method in order to improve efficiency and accuracy on cutting using OD-blade for hard and brittle materials, such as various ceramics, single-crystal silicon, etc. This new method is the cutting technique applying mechanical vibration. In this paper, the findings of this investigation on the vibration cutting applying low frequency vibration for a workpiece at parallel direction to the cutting, are reported. The main results obtained are as follows. When the vibration velocity amplitude is larger than the cutting speed (feed speed of the workpiece), grinding force in the vibration cutting is less than the one in the conventional cutting. The tool life in the vibration cutting is improved to compare with the conventional method, and further processing accuracy is improved. With this study, it is proved that this vibration cutting has the possibility of effective cutting method using OD-blade.
