摘要： A method and system compensates for vertical deflection for parts manufactured by a numerically controlled (NC) machine. The (NC) machine has an application head position programmed to a plurality of nominal tool coordinates. Each nominal tool coordinate has a horizontal coordinate, a rotational coordinate, and a vertical coordinate. A tool used to manufacture the part is placed on the NC machine. The tool has a plurality of actual tool coordinates, each actual tool coordinate has a horizontal component, a rotational component, and a vertical sag component. A difference between each vertical sag component and a corresponding one of the nominal tool coordinates is calculated. Each difference is multiplied by a multiplier value providing an adjusted sag value. Each adjusted sag value is subtracted from the application head position for each actual tool horizontal or rotational coordinate to compensate the part for the vertical sag of the tool during manufacture.

摘要： The present invention provides an NC machine tool which permits a check for the run-out of a spindle thereof at any time. The NC machine tool includes deflection detecting means (22) provided on a base within a machining area, and run-out diagnosing means (8) for conducting a diagnosis on the run-out of the spindle by calculating the amount of the run-out of the spindle on the basis of a deflection detected by the deflection detecting means (22) and comparing the calculated run-out amount with a predetermined tolerance. A test tool is attached to the spindle and rotated about an axis thereof, and the deflection of an outer circumferential surface of the test tool is detected by the deflection detecting means (22). On the basis of the deflection thus detected, the run-out diagnosing means (8) conducts a diagnosis on the run-out of the spindle. The diagnosis on the run-out of the spindle can be achieved through a simple and easy operation by moving the test tool into a detection area of the deflection detecting means (22).
