Recently, a lot of advanced materials have been developed. Therefore, the cutting conditions suitable for such materials are diversified, and the damage of the tool becomes complex. For example, temperature damage, steadily propagating wear, chipping of the tool edge, failure, etc, and those damages are created by the various causes. To analyze the tool damages, it is very important to make clear the stress induced in the tool under cutting operation. Main purpose of this research is to measure the dynamic cutting stress, especially in orthogonal cutting, momentarily by applying the caustic experimental method. The cutting conditions employed are; the cutting speed is 26.4 〜 659.7 m/min, the relief angle is kept as +15 degree constant, the rake angle is adjusted to +15 degree, 0 degree, -15 degree and the feed rate is 0.1 〜 0.5 mm/rev. The laser ray is irradiated to the cutting region, and the reflected and the caustic patterns created by the reflected light ray are observed. We investigated the effect of cutting conditions on the caustic patterns. As the result, it was obtained that the size of the caustic pattern increases with the cutting resistance. In addition, the shape of the caustic curves becomes smaller gradually with the decrease of the rake angle.
