Abstract
This paper presented several newly developed contouring systems for the different testing purpose of CNC machine tools. The first system, a quadrant sensor contouring system with a small contouring radius, composed of a laser diode and a quadrant sensor, was employed for checking the dynamic performance of a CNC machine tool. The second system, an optic scale contouring system with a larger contouring radius, composed of an optic scale and the designed linkages was developed for the verification of the positional error and the volumetric error of a CNC machine tool. The third system, a 2D optic encoder contouring system was introduced to test the performances of CNC machine tools under various NC paths. Finally, a self-supported linkage measurement device was described for checking the contouring performance of a CNC machine tool under the actual cutting conditions. Experimental works were carried out and the test results showed these proposed systems are successfully applied to test a CNC machine tool.
