The dynamic error of CNC machine tools, which often exceeds the quasi-static error at high-
speed machining, becomes the main reason affecting the machining error of the sculptured …

Computer numerical control (CNC) machine tools are widely used in various industrial fields
ranging from aerospace, automotive, ship building, and the die/mould to manufacture …

Modern high-speed 5-axis machining toolpaths consist of densely discretized tool center
points (TCP) and tool orientation vectors (TOV). This paper presents a global interpolation …

Linear motion commands of computer numerical control (CNC) machine tools need to be
smoothed at the transition corners in order to guarantee continuous and steady machining …

Tool path smoothness is important to guarantee good dynamic and tracking performance of
robot manipulators. An analytical C 3 continuous tool path corner smoothing algorithm is …

Five-axis linear toolpaths (or G 01 blocks) are widely used in CNC machine tools. The
tangential and curvature discontinuities at the corners of linear toolpath result in feed …

axis machining tool-paths, when programmed in workpiece coordinates, translational and
rotational tool motion in terms of Cartesian tool center points (TCPs), and unit tool orientation …

A novel analytical five-axis path-smoothing algorithm is developed for the high speed
machining of a linear five-axis tool path. Segment junctions of the linear tool path in the …

In this paper, a time-optimal trajectory planning method based on quintic Pythagorean-
Hodograph (PH) curves is proposed to realize the smooth and stable high-speed operation …

The joint dynamic constraints of robot manipulators are normally set to conservative constant
values to meet the dynamic tolerances at different poses, which leads to incomplete …
