Field of the Invention The present invention relates to a program of a CNC (Computer Nemeric Control) system. In particular, it is about A CNC drilling program generator, a method for generating a CNC drilling program, and a computer-readable recording medium for recording a computer that causes a computer to execute the function of generating a CNC drilling program. 2. The previous technical description At present, the general CNC drilling program usually requires many complicated editing and calculation procedures before it can be completed. As shown in Figure 1, at the beginning, the original program for drilling must be obtained and entered into CAD / CAM (Computer-Aided Design / Computer-Aided Manufacture) for typesetting and editing. It takes about several hours. PE2 software is used for editing and calculation, such as zero point setting, drill conversion, printing holes, testing holes, slotted holes and round holes, etc., which need to be manually entered into PE2 through manual calculation. Not only does the operation take a long time, the file is large, and serious Ground affects the operation of the production line. In addition, human editing is prone to errors, and trial drilling must be performed to ensure that the program is correct before mass production can begin. In addition, for a small variety of drilling operations, the previous very tedious work, but only a small amount of work, is very cost-effective. Usually electronic circuit designers only provide single-chip programs to printed circuit board factories. Engineers must edit and calculate drilling programs, and must operate under CAD / CAM and PE2. Only a few programs can be processed for several hours, which is not only a waste of time and human The calculation operation is unavoidable, and it needs to be revised and recalculated, and the work efficiency cannot be improved. -4- This paper size is applicable to China National Standard (CNS) A4 (210 X 297 mm) (Please read the precautions on the back before

Description of the invention (4) At the stop t * u The length of the slotted hole or the diameter of the circular hole is entered at this time. At this time, the drilling core data has been entered. The CNC drilling program generator of the present invention can automatically calculate according to the original program and the drilling data. To generate a drilling program that can be executed on a CNC machine. According to the original program and the drilling data, first, when the input use quadrant is 1 or 4, the subprogram A is called to perform the calculation of the zero setting (χ axis), as listed in formula (1): Q-12 .008-x + 2 + 25.4 (1) where X is the actual total length and width. The fixed format of the Q value is 6 digits, and two digits are kept before the decimal point, otherwise 0 is added, and the decimal point is not marked. For example: if the Q value is calculated as 1.234, the value stored in the format content position should be 0123 40. The so-called "format content position" is a specific "format content position" where the q value should be placed in the cnc drilling program. If the input quadrant is 2 or 3, call subroutine B and perform the calculation of zero setting (Z axis), as listed in formula (2): Q = 12.008 -y + 2 + 25.4 (2) where y is Actual total length and width. According to the input data, the diameter of the drill pin is in millimeters (mm). Therefore, it must be converted into English leaves (.inch). The calculation is performed when the actual iron head is a general hole (drill pin diameter / 25.4) And stored in "format content position", when the actual drill bit is a square hole or a circular hole, it is calculated (1.2 / 25.4) or (3.0 / 25.4) and stored in "format content position".
