Research on Error Compensation Techniques for NC Machine Tools

Abstract:

Cause of machining error for NC Machine Tools is described, and principle of NC machinings error compensation on the basis of the existing in-line detection model of NC machine tools is analyzed in this paper. Regularity of error Modeling based on multi-body system is found,accordingly, we will find the corresponding characteristic matrix and transformation matrix if location features and sport features of the adjacent body are confirmed. Then, formula of error model is found, and we can get numerical solution and compensate error according to the identified error parameter. As a result, the machining accuracy of machine tools can be greatly improved.
