| Abstract: | This paper analyzes the reason of thermal error on NC machine tool and its characterist ics synthetically, introduces the basic principle of its on-line measurement usi ng laser interferometer simply and expatiates the execution process of thermal e rror compensation for NC machine tool. Making full use of programmable logical c ontroller (PLC)'s strong anti-jamming ability, high reliability, quick calculati on and excellent interface performance, this paper presents the hardware system' s implementation method for thermal error compensation of NC machine tool. The a pplication of PLC improves the precision of error compensation, which is an impo rtant reference to the hardware implementation of error compensation. |
