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.

Method of estimating adjustment amount for support position of support device, method of adjusting support position of support device, and apparatus for estimating adjustment amount for support position of support device

A reference mirroris disposed on a table, a first laser displacement sensor Lfor measuring a machined surface of a workpiece W and a second laser displacement sensor Lfor measuring a reference surface of the reference mirrorare disposed to a tool holder. A measurement motion applying sectioncauses the tableand the tool holderto relatively move in a sinusoidal trajectory, and a sensitivity calculating sectioncalculates sensitivity of the first laser displacement sensor Lbased on machined-surface displacement data and reference-surface displacement data which are measured during the relative movement. Subsequently, an actual shape data calculating sectioncorrects the machined-surface displacement data based on the calculated sensitivity, and calculates actual shape data of the machined surface by taking the difference between the corrected machined-surface displacement data and the reference-surface displacement data.
