Integrated Real Time Compensation System for Thermally Induced Volumetric Errors in Commercial CNC machine tools

摘要

Thermally induced errors have been significant factors affecting the machine tool accuracy. The thermal errors generally come from the thermal deformations of the machine elements caused by heat sources that exist withinthe structure, ball screws, bearings, nuts, axis drive motors, friction onthe way surfaces, cutting processes, the flow of coolant/lubricating oil, and the ambient temperature. Those thermal errors have been reported as much as about 70
