Reliability analysis of CNC machine tools
Reliability Engineering, 1982A 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, 2014The 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, 1997Machine 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)].

Feedback Interpolators for CNC Machine Tools
Journal of Manufacturing Science and Engineering, 1997This paper presents interpolators that are capable of generating 2D curves in general implicit forms and 3D curves in general parametric forms. In contrast to the existing interpolators, which utilize complicated algorithms to meet the interpolation requirements such as maintaining high accuracy and constant feedrate, the proposed interpolators utilize

Weighted Multilateration in Volumetry of CNC Machine Tools
2018Our research study describes utilization of a weighted multilateration principle in the multi axis machine error modeling. Multilateration plays on of the most important role in the identification of the exact position of the point in the machine tool work space. Using laser tracer, the measured data were obtained in spherical coordinates.
