RISInterpolation Error Prediction of a Three-Degree Parallel Kinematic Machine
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, an NC interpolation algorithm for a tripod-based parallel kinematic machine is investigated. The algorithm can be implemented in two steps, the rough interpolation in the Cartesian ...
A General Approach for Geometric Error Modeling of Lower Mobility Parallel Manipulators
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents a general and systematic approach for geometric error modeling of lower mobility manipulators. The approach can be implemented in three steps: (1) development of a linear ...
An Approach for Acceleration Analysis of Lower Mobility Parallel Manipulators
Publisher: The American Society of Mechanical Engineers (ASME)
