A Study of Improvement of Machining Accuracy Induced Thermal Deformation

열변형에 따른 가공 정밀도 개선에 관한 연구

Development of high speed feed drive system has been a major issue for the past few decades in machine tool industries. The reduction of the tool change time as well as rapid travel time can enhance the productivity. However, the high speed feed drive system generates more heat in nature, which leads thermal expansion that has adverse effects on the accuracy of machined parts. The detail of the model proposed is described in the paper together with the experimental methodologies using a proposed compact measurement system to examine the validity of the proposed approach. The results showed the machining accuracy could be maintained to better than $\pm$5${\mu}{\textrm}{m}$ while using this T-18 sensor
