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 ...

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.
