Claim 8:
9. A method for manufacturing a component using a computer numerical control (CNC) machine tool having a machining module selectively controllable to machine the component and a coordinate measuring machine (CMM) module that is selectively controllable to determine a set of multi-axis coordinates for one or more surface points on the component, the method comprising:
(a) controlling the CNC machine tool to modify at least one surface of the component;
(b) controlling the CMM module to determine multi-axis coordinates for one or more surface points on the modified surface of the component;
(c) determining one or more surface position variances using the reference inspection data and using the multi-axis coordinates for the one or more surface points on the modified surface;
(d) determining if any of the one or more surface position variances exceeds a threshold;
(e) creating one or more executable correction action instructions for controlling the CNC machine if the one or more surface position variances exceed the threshold; and
(f) repeating steps (a) through (e) until the one or more surface position variances are within the threshold.
