A theoretical expression of a workpiece (W) the curved surface of which is measured by a measuring probe () equipped with a stylus () is specified, a measuring area where the measurement is executed on the measuring surface of the workpiece (W) is determined, and the axis angles of the stylus () are determined based on the coordinate values and the normal vector of a representative point determined in the measuring area.

Method for measuring curved surface of workpiece, program and medium thereof

A linear measuring machine is provided, the linear measuring machine having a base ( ), a column ( ) disposed on the base, a slider ( ) elevatable along the column and an elevation driving mechanism ( ) including a motor for lifting and lowering the slider. The linear measuring machine further includes a touch-and-back mechanism for driving the elevation driving mechanism in a direction for a probe ( ) to move away from a measurement surface of the workpiece after fetching a detection value of a displacement sensor ( ) when the probe touches the measurement surface of the workpiece and for stopping the elevation driving mechanism.
