    摘要: A thermal displacement estimating method includes: detecting each temperature of a predetermined heat generating portion and a predetermined main body structure portion by a temperature measurement device; and estimating a thermal displacement of the heat generating portion by an estimation model based on a detected temperature. The estimating of the thermal displacement includes: obtaining a conversion coefficient equivalent temperature change amount equivalent to a change amount of a conversion coefficient before and after a cooling capacity change from a relationship between a predetermined cooling heat amount of a cooling device and the conversion coefficient between the temperature and the displacement for estimating the thermal displacement from the detected temperature and/or a cooling heat amount equivalent temperature change amount equivalent to a changed heat amount before and after the cooling capacity change from a relationship between the predetermined cooling heat amount and a temperature equivalent to the cooling heat amount.
