Abstract
This study is aimed to measure the deflection of loaded table on machine tool. The deflection rate is measured then the table is in a stationary state and is moved. In conclusion we have found that the more load increases, the more the table deflections. Also, we have found that the deflection rate increases in accordance with the speed of movement. Therefore, we have concluded that inspection of machine tool should be done considering the weight of load and the speed of movement. However, since the condition of accuracy test for domestic brand of machine tool is defined as unloaded case, measures should be explored only for loaded case.
