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...

Abstract

The invention provides an automatic programming method for processing the finish machining allowance of a die. The method comprises the following steps of: 1, saving a processing program in a TXT format in the G code form; 2, reading data of the processing program TXT document; 3, extracting a row of data from the processing program document in sequence, and classifying and integrating the information; 4, judging whether the data extracted in the step 3 needs to be corrected, if YES, skipping to the step 5, and otherwise, skipping to the step 7; 5, obtaining the size and vector direction of the machining allowance; 6, correcting the machining G codes according to the size and the vector direction of the machining allowance, and outputting a new G code; 7, directly outputting the remainingprocessing G codes to a text window, extracting the next row of data from the processing program TXT document, if the next row is the last row, ending a G code modification part in the automatic programming, and otherwise, skipping to the step 3. According to the invention, the numerical control programming efficiency can be improved, and the error rate is reduced.

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...
