Precision measurement method of “cradle-type” five-axis machining center
The International Journal of Advanced Manufacturing Technology, 2021This study mainly measures the accuracy of closed impeller machining machines in aerospace. However, this machining center is different from others and belongs to a “cradle type” five-axis machining center. The measuring difficulty of cradle-type five-axis machining center is that the error accuracy of X, Y, Z, B, and C axes can meet the requirements ...

Numerical and experimental modeling of thermal errors in a five-axis CNC machining center
The International Journal of Advanced Manufacturing Technology, 2018This work aims at the establishment of methodology to model and analyze the thermal errors of a five-axis CNC machining center, from an estimated temperature field, to finally model an artificial neural network (ANN) algorithm to accurately predict with robustness the thermal error. The thermoelastic behavior of the machining center was modeled through
