When the spindle buits in machine tool rotates with very high speed, it may be shortened by the centrifugal force, and in contrast elongated by the thermal effect, resulting in the deterioration of the machning accuracy Whilst the speed is in low or moderate range, the displacement behavior is rather simple, therfore its compensation is easy. In very high speed range, the spindle shows complicated behavior in its displacement because of the additional effect of the centrifugal force, and duty the conventional compensation becomes erroneous. This paper describes that the spindle displacement can be represented with a linear equation considering the historical data for function values of the spindle speed. A multiple regression analysis is used to determine the coefficients in the linear equations.
