    Abstract: A cutting tool adjustment method is disclosed to lower a cutting tool on a transparent Mylar to produce an indentation before actual scribing operation, and then to pick up the image of the indentation, and then to use a numerical analysis method and the set formula to automatically calculate the correction angle and position and to adjust the angle and position of the cutting tool subject to the calculation result, and then to repeat the calculation and adjustment procedure if necessary. Thus, the cutting tool and its cutting edge can be accurately adjusted to the correct angle and position to obtain a precise indentation. Further, by means of the automatic adjustment procedure, the present invention saves much adjusting time, thereby improving the productivity.
