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)].

Load spectra of CNC machine tools
Quality and Reliability Engineering International, 2000Load spectra of CNC machine tools are described in this paper; 112 CNC machine tools have been traced for 3 years. Data including machining parameters and conditions, drawings and NC programs of parts, process cards and specifications of each individual CNC machine tool are gathered. A database containing this information is designed.

Parametric Programming of CNC Machine Tools
Applied Mechanics and Materials, 2013CNC machine tools are increasingly often used in industry, and the development of the methods of their programming is also proceeding. Modern multipurpose multi-axial machine tools are programmed using special CAD/CAM software programs. Universal special programs for controlling CNC machine tools can, however, be generated in programs written in high ...

2009
The introduction of CNC machines has radically changed the manufacturing industry. Curves are as easy to cut as straight lines, complex 3-D structures are relatively easy to produce, and the number of machining steps that required human action has dramatically reduced.

A high speed machining algorithm for CNC machine tools
IECON'99. Conference Proceedings. 25th Annual Conference of the IEEE Industrial Electronics Society (Cat. No.99CH37029), 2003This paper introduces a high speed machining algorithm based on a look-ahead interpolation technique for the machining of 3D surface obtained by a CAD/CAM system. Generally, specification of CNC system for high speed machining requires an additional hardware and it burdens end users with additional cost.
