3D Scanning System of Structured Light for Aiding Workpiece Position of CNC Machine Tool

This study develops a 3D scanning system using structured light of gray code for aiding workpiece position of CNC machine tool online. Resulted showed that the dimensional accuracy error of 3D scanning system after reconstructing 3D model points is about ±1mm for each axis. The repeated precision error of the 3D model edge points is about 0.05 mm. The running time of the 3D scanning system with automatic workpiece position is about 99~103 seconds.
