The spindle axial time-varying thermal error compensation method for horizontal boring and milling machine tool based on edge computing

[摘要] The time-varying thermal error of the horizontal boring and milling machine tool (HBMMT) directly affects the performance of high-end parts. The time-varying thermal error is in the axial direction due to the radial symmetry of the spindle box being good. The spindle axial time-varying thermal error compensation method based on edge computing was studied for reducing the effect of the spindle axial time-varying thermal error of HBMMT on the accuracy consistency of parts. The spindle axial time-varying thermal error model was established based on the speed and acceleration of spindle temperature change. The error compensation value was acquired by edge computing, and the error was compensated based on the principle of coordinate origin offset. The error fluctuation range with compensation was reduced, and the accuracy stability of HBMMT was greatly improved.
