Cnc Glass Cutting Machine, Automatic Programming System Design And Development

Glass has a good perspective, light transmission, reflection, insulation, sound insulation and high chemical stability of the properties, which make it essential to life. With the development of automotive, construction, decoration, furniture, the information industry and the rising requirements of people's living space, so the demand of glass is very broad, but advanced glass processing equipment comparing with foreign's, there is still a certain gap, producing automatic glass cutting machine independent has important practical significance, it will break the dependence on imported foreign equipment in the situation, meanwhile meet Market demand.The NC automatic programming system of glass cutting machine glass cutting that studied meets for the current market demand in this paper, combining with the actual production, developed an easy to use for automatic programming system software.The software could be running in PC. Operators Typesetting according to the pre-cut graphics layout, and then generate G-code for tools movement. coupled with the PMAC controller and other auxiliary equipments to achieve the automatic glass cutting machine programming,whitch Not only eliminates the shortcomings arising from manual programming, but also meets the requirements of glass cutting the use of desktop publishing.The issue process is according to the characteristics of glass cutting, and compares with other CNC glass cutting machine programming systems,then analyzes the key technology, so we selected a more appropriate Program and gave a detailed description of the automatic programming system designed ideas. First of all, the layout of the system is divided into rectangular layout, graphics library parametric and alien graphics layout. Rectangular layout is The most common used method, which refers to different sizes piece Typesetting on the original glass, requiring the highest possible utilization of glass.it bases on a hierarchical structure principle; parametric graphics library layout is also commonly used in the actual production of non-rectangular graphics layout, such as triangular, trapezoidal, circle, and parallelogram, etc. into the graphics library, the operators select graphics needed from the graphics library and set its parameters typesetting; alien graphics layout is more complex graphics for typesetting, the Manner of the layout is generally easy to use, but the layout is relatively simple manner, according to this feature can help AutoCAD-aided design, layout graphics to be ranked well in AutoCAD edition, save as the DXF file format, the system can read this file to extract anti-graphic information to achieve alien graphics layout. After the end of the three graphical layout,to generate G code,we should reduce Redundancy of graphic information, according to "the principle of the nearest point". The system can also carry out real-time monitoring system state, you can complete the processing of documents of historical inquiry, Can not only save sheet, reduce costs, improve processing efficiency and the quality of glass products, with considerable economic significance.
