Some Guidelines for Implementing Error Compensation on Machine Tools

摘要

Some guidance is presented for implementing error compensation for geometric and thermally induced errors of a machine tool. Error compensation has the potential for relatively low cost improvements in the accuracy of finished parts since machines are more repeatable than accurate and most errors are predictable and can be compensated. Measurement of individual error components and the development of a rigid-body, kinematic model of the machine tool is discussed. Some methods of implementing the predicted error compensation on existing machine-tools controllers is presented.
