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.
