Research on Recognition of Complex Shape Features in Castings and Automated Polishing Systems
In order to improve the efficiency of casting grinding,a deep research on grinding robot was done.The grinding robot can automatically recognize the complex shape of the casting,making the grinding more accurate.The design concept of the curved workpiece was studied as the test object.First,the point cloud data of the workpiece was measured by using a 3D profile scanner.The shape features were extracted by comparing the point cloud data of the original workpiece with the point cloud data of the workpiece with the shape of the weld convex and concave,and the CAD model of the actual workpiece was generated by using rational B-spline curve fitting,which was imported into the offline programming software.Automatically generate grinding track.In order to verify the correct-ness of the grinding track,the off-line simulation method was first used to simulate the grinding process,and then the simulated grind-ing track was uploaded to the grinding system for grinding the actual workpiece to improve the grinding accuracy.
