Abstract
Five-axis hybrid machine tools are widely used due to the advantages of high speed, high precision, and good performance in the aviation and aerospace manufacturing industry. Many scholars have stu...
Highlights
Parallel mechanisms have been widely applied in the manufacture of aviation and aerospace industry components with high speed, high precision, good dynamic performance, and other advantages
On the basis of previous research results, this work proposes an integrated error modelling method for the general 3-PRS-XY hybrid machine tool, and analyses the various error sources affecting position errors of the end-effector from the perspective of manufacturing. This method can separate the compensable and non-compensable error sources affecting the accuracy of the end-effector, and it is critical for the further accurate design and kinematic calibration of such a hybrid machine tool
The error model for the 3-PRS parallel spindle head and the X-Y serial workbench is established based on the theory of vector chains and small perturbations: an integrated error model of a hybrid machine tool is established
Summary
Parallel mechanisms have been widely applied in the manufacture of aviation and aerospace industry components with high speed, high precision, good dynamic performance, and other advantages. Keywords 3-PRS parallel spindle head, hybrid machine tool, error model, error source separation, sensitivity analysis
