Embodiment Construction
[0063] The present invention will be described in further detail below in conjunction with the embodiments and accompanying drawings, but the embodiments of the present invention are not limited thereto.
[0064] Such as figure 1 As shown, an automatic programming method for processing mold finishing allowance, including the following steps:
[0065] S1. Convert the processing G code from ptp format to TXT format to form a processing program TXT file, and install the corresponding language environment;
[0066] In this embodiment, step S1 converts the processed G code from ptp format to TXT format, and installs the corresponding language environment as follows:
[0067] Use the CNC programming software to export the processing G code, open it in Notepad, and save it in TXT format. Then install Microsoft Visual Studio 2010, where the header files needed for programming are as follows figure 2 shown.
[0068] S2. Read all the information in the TXT file of the G code as fol...

The present invention provides an automatic programming method for processing the machining allowance of mold finishing, comprising the following steps: 1. Save the machining program in the form of G code as TXT format; 2. Read the data of the TXT file of the machining program; 3. It extracts a line of data in the processing program file in order, and classifies and integrates the information; 4. Determines whether the data extracted in step 3 needs to be corrected. If it needs to be corrected, skip to step 5; otherwise, skip to step 7; 5. Obtain the size of the machining allowance and its vector direction; 6. Correct the machining G code according to the machining allowance size and its vector direction, and output the new G code; 7. Directly output the remaining machining G code to the text window, and extract the next line of data in the processing program TXT file, if the line is the last line, the G code modification part in the automatic programming ends, otherwise jump back to step 3; the present invention can improve the efficiency of numerical control programming and reduce the error rate simultaneously.
Description
technical field [0001] The invention belongs to the technical field of mold numerical control programming, and in particular relates to an automatic programming method for processing the finishing allowance of molds. Background technique [0002] NC programming is one of the main contents of the preparation stage of NC machining. It is the whole process from part drawing to obtaining NC machining program; it usually includes analyzing the part drawing to determine the processing process; calculating the tool path to obtain the tool position data; writing NC Processing procedure; making control medium; proofreading procedure and first piece trial cutting. [0003] CNC programming is divided into two methods: manual programming and automatic programming. [0004] Manual programming is a method in which programmers directly complete the whole process of part drawing process analysis, process and data processing, calculation and writing of NC programs, input of NC programs to p...
