Development And Test Research Of CAD/CAM/Robotic Integration Stone Engraving Systems

With the improvement of living standards, stone carvings become more popular in people’s daily life. The demand for stone handicrafts grows and stone carving gradually develops into an important industry. Currently the level of automation in stone carving is generally low in China. There are many problems of traditional processing methods of stone carving product. Stone industry is a high energy, highly labor-intensive, low-margin industry. Automation of the engraving process equipment needs strongly.Based on domestic stone carving mechanical defects and learning from foreign advanced processing methods, this paper develops a robotic stone carving system. The engraving system applies CAD/CAM ideas in stone processing, achieving a three-dimensional model created from stone products to the machining path generation and then integrated robotic machining process. The system takes advantage of industrial robots in space motion positioning, which overcome the disadvantage of domestic carving small machining range and the complexity of the object is not high enough.Firstly, according to the characteristics of the stone processing, an overall plan is developed, then completing the design of electronic part and mechanical part. To achieve the expansion of robot processing space, carried out positioner overall design and experiments. Positioner algorithms and hardware are Completed. Using Visual C++6.0as development platform, combined with solid high motion control library function to achieve the synchronized movement of the positioner and robot. In terms of the formation of cutter path, robot sculpture of cutter path generation process were studied. Achieved sculpture CNC machining trajectory by STL model and by CAM software. Finally, carved stone processing robot experiment shows the process and results, problems encountered during the experiment were analyzed. In the cutter path form, the cutter path generation for machining robot sculpture was studied sculpture realized by STL model CNC machining CAM software to generate trajectories and sculptures based CNC machining trajectory. Finally, carved stone processing robot experiment shows the process and results, problems encountered during the experiment were analyzed.CAD/CAM/Robotic integration stone engraving systems have the versatility, flexibility, high level of automation advantages. The research of stone engraving systems has positive significance, which can reduce labor costs, improve efficiency engraving, improve processing quality and reduce the cost of engraving.
