2.2 Demand analysis of the blanking system
The blanking optimization system in this paper is a computer-aided prototype system used to solve the optimization of sheet metal layout and blanking in enterprises. It has a better automatic optimization layout function and automatic CNC programming function. During the development of this software, through the communication with the engineering and technical personnel of the enterprise and the communication of the operating workers, the performance of the software has been improved to a certain extent. It has a strong practicability in helping companies save sheet metal raw materials, and at the same time can help enterprises save production Cost and improve economic benefits. The blanking optimization system for irregular sheet metal parts mainly has five major function modules, which are the data interaction function of the software, the preprocessing function of the blanking data, the display function of the part graphics, the automatic layout function of the part, and the automatic layout function. CNC programming function.
2.2.1 Data interaction function of software
A complete blanking system should have data input and output functions, so that operators can interact with the software more intuitively and complete the required tasks. The graphics files input and output by the company's general blanking software are in DXF format. This is also a consideration of the versatility of the file to ensure transferability when used in other systems. In addition to the graphics files, the processing path data after part layout And the CNC machining code should be stored in the background of the software.
The blanking optimization system in this paper has the following data interaction functions:
(1) Input of DXF format file and acquisition of part information;
(2) Display of part graphics and selection of required layout parts;
(3) Display of part layout results and layout files are stored in DXF format;
(4) Storage and acquisition of processing path information of parts;
(5) The numerical control program code of the layout result is generated and stored.
