Error Modeling and Sensitivity Analysis of a Five‐Axis Machine Tool [PDF]
Mathematical Problems in Engineering, 2014 Geometric error modeling and its sensitivity analysis are carried out in this paper, which is helpful for precision design of machine tools. Screw theory and rigid body kinematics are used to establish the error model of an RRTTT‐type five‐axis machine tool, which enables the source errors affecting the compensable and uncompensable pose accuracy of ...

Tool-path planning method for kinematics optimization of blade machining on five-axis machine tool
The International Journal of Advanced Manufacturing Technology, 2022 Abstract Planning tool-paths on free-form surfaces is a widely discussed issue. However, traditional methods of generating paths capable of meeting all the requirements of blade machining remain challenging. In this study, a new iso-parametric path-planning strategy based on a novel parameterization method combined with the conformal ...

Influence of Tool Length and Profile Errors on the Inaccuracy of Cubic-Machining Test Results
Journal of Manufacturing and Materials Processing, 2021 A cubic-machining test has been proposed to evaluate the geometric errors of rotary axes in five-axis machine tools using a 3 × 3 zone area in the same plane with different tool postures. However, as only the height deviation among the machining zones is
