The purpose of this thesis is to study a new contouring system for CNC machine tools. The system, which uses the tooling taser and photo diode of position sensor detector, is different form the traditional telescope magnetic Ball Bar system. The system is employed to obtain the contouring error in each of two single axises and these two error components also can be integrated as a radial error such as the error obtained by the Ball Bar system.
The work of employing the multi-single axis contouring system includes the displacement calibration of the PSDs, the setting-up of the PSDs mounted on the table, the lay out of the contouring path, the method deciding the start point and the end point in a contouring test, the intergration of the circularity and the research of contouring error of two single axis in the contouring test.
First, in the tesis the error of the CNC machine and other traditional contouring systems are introduced. Then, the software and the hardware of the system are described. The system is employed to test the CNC machine. At last, the analysis of the test results and some discussions and suggestions are provided in this system.
