Numerical control system and control method for achieving automatic optimization of tool paths based on DBF

Abstract

The invention relates to a numerical control system and a control method for achieving automatic optimization of tool paths based on DBF, and belongs to the technical field of numerical control system control. The numerical control system comprises a file information read module, a graphic primitive information analysis module and an NC code generation module. The control method includes that after DBF graphic files are read by the file information read module, graphs in the DBF graphic files are divided by the graphics primitive information analysis module according to a preset graphic primitive, and at last, NC codes are generated by the NC code generation module according to divided graphs. By adoption of the numerical control system and the control method, graphic information can be extracted from CAD graphs and converted to coordinate point data, combined with numerical control machining technique knowledge, the data are converted to the NC codes which can be identified by a machine tool to generate a numerical control program and achieve control of numerical control system machining, moreover according to the numerical control system and the control method for achieving the automatic optimization of the tool paths based on the DBF, the implementation mode is easy and convenient, implementation cost is low, and the application range is relatively wide.

Description

technical field [0001] The invention relates to the technical field of numerical control systems, in particular to the technical field of automatic machining control methods for numerical control machine tools, and specifically refers to a numerical control system and a control method for realizing automatic optimization of tool paths based on DBF. Background technique [0002] Graphical NC programming is the development direction of NC programming. For simple parts with less complex geometry, the calculation is simple and there are not many processing procedures. Manual programming is easier to implement, but for parts with complex shapes or a large amount of programs, manual Programming is hard work. Compared with manual programming, language automatic programming can improve programming efficiency several times or even dozens of times, but it must accurately describe and define each geometric body to be processed, and some complex geometric figures are almost difficult to...

AI Technical Summary

Problems solved by technology

[0003] At present, there are some software for realizing graphical NC programming, but most of the CAD drawing software used are difficult to master, and through the research of some lathe final products, it can be found that there are not many types of final processing graphics, and there is no need to use complicated ones at all. CAD drawing software

The software for drawing DBF graphics is easier to use than other software because of its small number of shapes.
