An easy rapid prototyping technique with point cloud data

In recent days, rapid machining through digital prototyping has been popula r for its applicability in a wide range of complex and useful parts. Rapid construction of prototypes from point cloud data based on section plane met hod is available, which is an approximate method. Discusses some suitable m ethodology for conversion of point cloud data to a physical prototype where data acquisition is through a mechanical touch trigger probing process usi ng CNC milling machine. The process is quite useful for reverse engineering of complex sculptured parts. A concept called tangent plane method is adop ted for the generation of 3D geometry on point cloud data of sculptured par ts with due emphasis on probe radius compensation after data capture and to ol radius compensation during tool-path generation. Computer simulated resu lts are presented, based on real-world point cloud data.
