In a method of manufacture, a displacement sensor is provided over a conditioner disk. The conditioner disk is rotated to perform a conditioning process on a polishing surface of a polishing pad. A displacement of the rotating conditioner disk is detected using the displacement sensor during the conditioning process. A height of the conditioner disk is calculated from the detected displacement. An end point of the conditioning process is determined on the polishing surface based on the calculated height.

A substrate processing apparatus includes a rotary table configured to move each of multiple substrate chucks to, in sequence, a carry-in position where a carry-in of a substrate is performed, a processing position where thinning of the substrate is performed, and a carry-out position where a carry-out of the substrate is performed; a tilt angle adjusting device configured to adjust a tilt angle of the substrate chuck with respect to the rotary table at the processing position; and a tilt angle controller configured to control the tilt angle adjusting device based on a measurement result of a plate thickness measuring device. The plate thickness measuring device measures a plate thickness of the substrate at the carry-out position.

The present application discloses a method for calibrating a measuring probe in a gear cutting machine by using a workpiece received in a workpiece holder of the gear cutting machine, wherein the measuring probe includes a measuring probe tip which is movably arranged on a measuring probe base, wherein the deflection of the measuring probe tip relative the measuring probe base can be determined via at least one sensor of the measuring probe, and wherein the measuring probe is traversable relative to the workpiece holder via at least two axes of movement of the gear cutting machine. The method comprises rotating the workpiece via an axis of rotation of the workpiece holder and traversing the measuring probe via the at least two axes of movement of the gear cutting machine such that in the case of a perfect calibration the touch point of the measuring probe tip on the tooth flank would remain unchanged.

The present invention provides a measurement device for grinding wheel. One or more thickness measurement device is disposed slidably on a platform. A spinning device is disposed on the platform. A grinding wheel is fixed on the spinning device. The spinning shaft spins the grinding wheel. The one or more thickness measurement device measures the flatness condition of the grinding wheel. Furthermore, according to the present invention, a diameter measurement device is disposed inside the platform and measures the roundness of the outer periphery of the grinding wheel. Since the structure can be disassembled easily, the whole measurement device for grinding wheel can be carried conveniently. In addition, measurements can be performed by users on the site where the grinding wheel is located for real-timely understanding the real size and wear condition of grinding wheel.
