Research on Thermal Error Compensation Technique of the Screw

Abstract:

In the system of the machine tool, the position error is directly affected by the thermal deformation of ball screw. Screw system is a complex thermal system, which is affected by the processing conditions, the processing cycle, the use of cooling fluid, and the surrounding environment. Due to non-linear and interaction of the thermal error, a RBF network thermal error model is proposed in the paper and the model is tested in XHFA2420 large machining center.
