Reliability analysis of CNC machine tools

Reliability Engineering, 1982
A reliability and maintainability study of computer control (CNC) machine tools is described. For this analysis field failure data collected over a period of three years on approximately 35 CNC machine tools during their warranty period were analysed. In order to apply quantitative reliability methods, a coding system was devised to code failure data ...

Geometric accuracy of CNC machine tools

Proceedings of the 16th International Conference on Mechatronics - Mechatronika 2014, 2014
The present article is dedicated to the identification and interpretation of geometric errors of CNC machine tools. Identification of geometric errors plays a large role in the construction of the so-called “Error maps”. These maps can be used to describe the behaviour of the machine in the workspace without load or under conditions of finishing ...

Dynamic calibration of CNC machine tools

International Journal of Machine Tools and Manufacture, 1997
Machine calibration has become an important tool for assessing and maintaining machine accuracy, and for providing a measure of production quality. The calibration techniques supported by the calibration standards and the available metrology technology use static measurement cycles [BS3800, Part 2 (1991); ISO 230-2, Part 2 (1988)].
