  • Form measuring apparatus and form measurement method
    Patent number: 9366522
    Abstract: Stylus head displacer displaces a stylus head on a first measurement path. A path definer defines the first measurement path. A displacement controller controls the stylus head displacer such that the stylus head displaces along the first measurement path. A position detector detects a position of the stylus head. A depression amount detector detects the depression amount of the stylus head. A measurement results memory stores the position and amount of depression of the stylus head. The depression amount detector outputs an error signal when detecting a measurement error. The displacement controller stops displacement of the stylus head in response to the error signal and displaces the stylus head to a starting point of the first measurement path, and controls the stylus head displacer such that the stylus head is displaced from the starting point to an end point of the first measurement path with a fixed depression amount.
