摘要
This paper deals with the reliability design of elements of computerized numerical control (CNC) machine tools and the practical applications of multidimensional force spectra of CNC machine tools described in part one of this paper. To illustrate the application of multidimensional force spectra, part two considers the design example of an S1-273 CNC lathe. First the force distribution of transmission elements is calculated. Then the equivalent fatigue force with specified reliability for the important transmission elements of the lathe under various working conditions is calculated. Use of the equivalent fatigue force determined to design the CNC lathe element enables obtaining the expected reliability. (C) 2003 Elsevier Science Ltd. All rights reserved.
