Abstract:
A coordinate measuring machine (industrial machine) includes: a column and a support that extend along the Z-axis; a beam being provided between the column and the support; a slider being movable on the beam; a ram being held on the slider movably along the Z-axis direction; a temperature detecting sensor and a temperature detector that detect the respective temperatures of the column, the support and the ram; and a shift amount calculator that calculates a Z-axis shift amount based on the respective temperatures of the column, the support and the ram, reference position data indicating a positional relationship between the column, the support and the ram at a reference temperature, and respective thermal expansion coefficients for the column, the support and the ram.
