Abstract
A support position adjustment amount estimation apparatus includes a reference load data storage storing reference load data for each support device obtained when a reference surface of a machine tool is in a leveled condition, a relational equation storage storing a relational equation between an amount of variation of a support position in each support device from a reference support position and an amount of variation of a load in each support device from the reference load data with the support position in one support device selected from three or more support devices fixed, and an adjustment amount estimator estimating a support position adjustment amount for each support device other than the fixed support device based on load data detected in all of the support devices, and the reference load data for all of the support devices, and the relational equation.
