재제조를 위한 노후 선반 스핀들의 열적 안정화 설계에 관한 연구

다국어 초록 (Multilingual Abstract)

Decrepit lathe can be functionally upgraded to like-new or with enhanced performance through remanufacturing. Remanufacturing can reduce resource consumption and waste generation. Machining accuracy is often affected by thermal errors, and spindles are one of the main sources of thermal errors in machine tools. In this study, an optimal design was developed to thermally stabilize the spindle of a machine tool to be remanufactured. The spindle bearing position, diameter of the shaft, and the length of the shaft were selected as design variables, and the object functions of the optimal design were the thermal deformation and the temperature of the spindle. Experiments were performed using computer aided design. As a result, the temperature and thermal deformation of the optimized model were decreased compared with the initial model. The optimized model can be applied to improve the accuracy of a spindle on a decrepit lathe after remanufacturing.
