Abstract: A drilling drive system is provided. The drilling drive system has a mast having a longitudinal axis and a surface extending along the longitudinal axis. A bar is fixed to the surface of the mast and extends along the longitudinal axis. A plurality of rungs is disposed along the length of the bar, and a floating chain is disposed around the mast. A drive sprocket has a plurality of teeth that engage the plurality of rungs and the floating chain.

Abstract: A system is disclosed for use in measuring a component. The system may have a probe configured to generate signals associated with a proximity to actual target points of the component, an actuator configured to move the probe relative to the component, and a controller in communication with the probe and the actuator. The controller may be configured to receive coordinates of intended form target points, to determine coordinates of the actual target points of the component relative to a component datum based on the signals, and to make a comparison of the coordinates of the intended form target points and the coordinates of the actual target points. The controller may also be configured to generate a deviation report based on the comparison, and to filter information from the deviation report according to wavelength into a plurality of deviation categories corresponding to component specification requirements of the component.
