ABSTRACT:
A method for controlling operations of a measuring machine is provided. The method includes the steps of: clearing faults when there are the faults occur in a measuring machine; sending a restart instruction via a control card to the measuring machine for controlling the movable arm to return to an initial position in relation to an X-axis, a Y-axis and a Z-axis directions; sending a move instruction comprising information of a final position to the control card; executing the move instruction; calculating a current position of the movable arm according to a count tracked by a raster ruler; determining whether the movable arm locates at the final position of the measuring machine according to the count; and controlling the movable arm to move along the measuring machine by executing a next move instruction, if the movable arm locates at the final position. A related system is also disclosed.
