It is the first time a laser diode and a quadrant sensor have been employed to build a simple contouring measuring system for testing dynamic performance of a CNC machine tool. The experimental work on a CNC machine tool with a Fanuc OM controller for various contouring paths under specified feed rates is carried out. Then, the compensation work is executed with the assistance of this developed contouring system. After the compensation, the contouring error, especially at a high feed rate and small radius, is reduced significantly.Computer control systemsControl equipmentCuttingError analysisMachiningNumerical control systemsSemiconductor lasersSilicon sensorsComputer numerically controlled (CNC) machine toolsMachine toolsconference paper10.1243/09544050215204182-s2.0-0036267428
