| With the rapid development of manufacturing industry of China,the demand for high-speed CNC machining is increasing.Meanwhile,High-speed CNC carving and milling machine has brought bright prospects for the advertising industry as a high-tech equipment developed as a whole.However,the traditional engraving and milling equipment needs artificial long-term delivery and correction of materials,which is dangerous.In this thesis,the realization of automation and digitization of engraving and milling machine is studied to further reduce the cost of enterprise personnel and improve the product yield.Based on the research of related literature at home and abroad,this thesis realizes the vision-based engraving and milling machine software.The main research contents are as follows:1)The software functional requirements of engraving and milling machine equipped with CCD industrial camera are analyzed.The hardware platform of the software application and the function and implementation process of each module in the software are introduced.2)An analytical method is designed for CAD files of DXF file format and the discrete point analysis method of spline curve element is studied.The computational complexity is optimized by improving the discrete criterion of spline curve.3)The method of material localization based on vision and the application of algorithm to optimize the machining path are studied to realize the precise machining of materials,improve the work efficiency and reduce human intervention.4)Developed the software of engraving and milling machine based on vision.The functions of parsing CAD graphics file,correcting and optimizing machining path are realized.The software can realize accurate calculation of material processing,effectively improve the efficiency of engraving and milling machine,reduce the accumulation of processing defective products and material waste.Finally,the whole thesis is summarized,some prospects for improvement are put forward. |
