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.

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.
