The measuring unit 42 measures the length of the tool to determine the starting position of the tool in the machining unit, and transmits the information of the starting position to the machining module 4 (4) For example, the electric control unit 43 sets the starting point of the machining according to the starting position of the tool., i^Sl〇9. Download the numerical control code to the processing module for NC machining. The computer numerical control unit 43 is based on the post processing unit 32. The generated NC code and the starting position of the tool obtained by the measuring unit 42 control the machining unit movement 41. The method of adding the first method of the present invention is to establish an X-turn to save the processing unit that has the initial processing surface. And the grinding wheel database that holds the information of the grinding wheel, when grinding a certain tool, the φ is used to decompose the tool to be processed: the L surface 'selects the processing unit corresponding to each processing surface from the process database to display The grinding wheel data selection selects the grinding wheel of the processing surface to form a processing technology suitable for tool grinding processing by combining the H art units. In summary, the invention has indeed met the requirements of the invention patent, and patented according to law. The above is only the preferred embodiment of the present invention, and the scope of the patent application is not limited thereto. Any equivalent modifications or changes made by those skilled in the art to the spirit of the present invention are It should be covered by the following patent application. 098124275 [Simple description of the drawing] Form No. A0101 Page 9 of 16 0982041442-0 201103698 [0044] Fig. 1 is a block diagram showing the system composition of a processing apparatus for grinding a tool by a grinding wheel according to an embodiment of the present invention. 2 is a flow chart of a tool grinding process using the processing apparatus shown in FIG. 1.
