Abstract
The volumetric error of a measurement-processing integrated machine tool was studied by using a complicated surface workpiece grinding machine as a special example. The model of volumetric error was established by using homogeneous transformation matrices, and the effect of volumetric error on coordinate transformation between the measurement and the processing work station was analysed. Various error components of the machine tool were measured with a laser interferometer and an electronic level, and the volumetric error was compensated by external software. With a ball bar system and grinding experiments, the volumetric position accuracy was tested after compensation. The experiment results illustrated that both the volumetric position accuracy and machining precision were improved dramatically after compensation.
