1. A system for manufacturing a component, comprising:
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;
a correction module in communication with the CMM module and the correction module is in communication with stored reference inspection data relating to the component; and
a system controller in communication with the CNC machine tool, the correction module, and non-transitory memory storing instructions, which instructions when executed cause the system controller to:
(a) control the CNC machine tool to modify at least one surface of the component;
(b) control the CMM module to determine said multi-axis coordinates for the one or more surface points on the modified surface of the component;
(c) determine 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) determine if any of the one or more surface position variances exceed a threshold; and
(e) using the correction module, create 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) repeat steps (a) through (e) until the one or more surface position variances are within the threshold.
