Modeling method of CNC tooling volumetric error under consideration of Abbé error [PDF]
The International Journal of Advanced Manufacturing Technology, 2022 AbstractThe Abbé error is a key factor for high-precision CNC machine tools. Unluckily, it is not taken into account in traditional machine tool volumetric error models. In this respect, based on the traditional machine tool volumetric error models, a new machine tool volumetric error model containing Abbé error is performed by analyzing the mechanism ...
