1. An adaptive machining system comprising:
- a numerical control (NC) machine configured to machine a component based on a machine tool program code;
a model comparison unit configured to compare electronic measured dimensional surface data of the component with an electronic surface model of the component;
a compromise shape determination unit configured to determine a compromise shape for the component based on the comparison, wherein the compromise shape determination unit comprises a model transformation determination unit configured to modify the electronic surface model based on the comparison, wherein the compromise shape determination unit comprises an offset distribution determination unit that is configured to determine a compromise offset distribution between the modified electronic surface model and the electronic measured dimensional surface data, wherein the offset distribution determination unit is configured to apply the compromise offset distribution to the modified electronic surface model to have a rate of contour deviation within a predetermined tolerance of 0.005 inch/inch; and
a program modification unit configured to modify the machine tool program code based on the compromise shape by modifying at least one line of the machine tool program code.

Abstract
In some examples, an adaptive machining system may include a model comparison unit, a compromise shape determination unit, and a program modification unit. The model comparison unit can be configured to compare electronic measured dimensional surface data of a component with an electronic surface model of the component. The compromise shape determination unit can be configured to determine a compromise shape for the component based on the comparison. The program modification unit can be configured to modify a machine tool program code based on the compromise shape.
