Robot manipulators with 6 degree-of-freedom (DOF) have advantages of good flexibility and
large working space. However, the relatively low stiffness deteriorates the machining …

Robots are increasingly employed in machining applications, such as milling, grinding and
polishing, etc, and contour error can be used to assess the robotic machining accuracy …

G01 commands generated by computer-aided manufacturing (CAM) software need to be
smoothed to eliminate the tangential discontinuities at corners. Although the smoothing …

Existing contour error pre-compensation methods are sensitive to modeling errors during the
prediction of contour errors. This article proposes an adaptive contour error pre …

This paper focuses on solving the contour performance reduction problem caused by
inaccurate contour error estimations. We will show that the task coordinate frame (TCF) …

Considering the amount of unmanned aerial vehicles (UAV) and the forthcoming new kinds
of UAV's, it is important to design a control strategy for different kinds of UAV's tasks to …

To address the inaccurate contour error calculation problem in traditional cross-coupled
control (CCC) methods for biaxial motion systems, this paper presents a novel CCC method …

Five-axis linear commands are blended as the local smoothed toolpaths by inserting
clothoid and airthoid splines at corners in five-axis CNC machining. The contour error is the …

The machining accuracy is mainly indicated by the contour error especially in high-precision
processing. Previously, scholars have proposed many controllers to reduce contour errors in …

Most of the molds of automobile panels are spliced with insert-type modules. Sudden
variations in load and impact vibration can occur while processing splicing area, which …
