Abstract
A surface texture measuring machine includes a vertical V-axis column D, a vertically movable table E, a horizontal X-axis guide and a slider disposed on the vertically movable table E, a probe C attached to the slider a V-axis detector a displacement detector an X-axis detector and a control device CPU. The control device CPU calculates the amount of a bending deformation in the X-axis direction at the height of the X-axis guide from a height signal from the V-axis detector and a displacement amount signal from the X-axis detector and sets a value that is obtained by subtracting the bending deformation amount from the X-axis direction displacement amount, as an X-axis displacement in measurement.
