Research Of Nesting System Based On QT Platform For Raiser Cutting

The nesting system is widely used in computer aided intelligent manufacturing,in the research of the past nesting system,the main research gaps are that the researchers mostly separated the CAD software from the nesting system.But in the actual application process,the two are function docking,the platoon-like system relies on the CAD module reading and editing function to display the nesting effect,finally enters the cam processing cutting link.At present,domestic and foreign mature nesting software support CAD/CAM system integration.The paper researches and realizes the nest system with complete CAD module function based on the open source framework,and solves the problem that the system function is simple in the traditional layout algorithm research background.With the analysis of DXF format data and graph metadata structure,the paper in-depth analysis the parts from the CAD file access,finds out system Data transformation and processing,problems,carding the reasons for the pretreatment process and the necessary,the two parts of the pretreatment of the layout of the part of the discussion and research,put forward a part of the feature information to solve the idea,The realization scheme of collision detection by envelope rectangle in the nesting system is proposed.Secondly,based on the specific circumstances of the open source framework,the paper analyzes the technical docking standards such as the implementation technology and the design mode of the framework,and probes and filters the nesting algorithm,realizes the layout system of the function of the complete CAD module,and designs the extended cam function.
