Abstract
A gear measuring method allows multi-point continuous measurement using a touch probe and is capable of reducing measuring time compared with known methods. For example, a base action for moving a sensing element of a touch probe along an ideal tooth form line of a workpiece (gear; W) or a tooth form line determined by calculation by controlling the movement of the sensing element and the rotation of the workpiece (W) and, in addition, an oscillation action for receiving first signals (ON signals or OFF signals) from the touch probe by bringing the sensing element into contact with the tooth surface of the workpiece during the base action and subsequently for receiving second signals (OFF signals or ON signals) from the touch probe by moving the touch probe in a direction along which the sensing element is separated from the tooth surface of the workpiece are continuously performed.
