The thermal error model of the 5-axis grinding machine tool was acquired by the homogeneous coordinate transformation, including 17 thermal error components. The thermal volumetric error real time compensation model was built by using the multiple regression analysis. The thermal error compensation control system and the temperature sensing system were developed and used as real-time compensation for the 5-axis grinding machine tool.

Basic Experiments

In order to apply the floating nozzle method to an angular grinding on the external cylindrical grinding, basic experiments on V-groove grinding with the wheel edge were performed on the surface-grinding machine. The results showed that the floating nozzle method could maintain a good control of the wheel edge wear, leading to improved surface roughness compared with a conventional nozzle.

Complicated Surface

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.

The Individual

In this paper, a new method is presented for the identification of machine tool component errors. Firstly, the Non-Uniform Rational B-spline (NURBS) is established to represent the geometric component errors. The individual geometric errors of the motion parts are measured by laser interferometer. Then, the volumetric error for a machine tool with three motion parts is modeled based on the screw theory. Finally, the simulations and experiments are conducted to confirm the validity of the proposed method.
