Analysis of material properties of internal surfaces using machining processes to enable stress relief in the material under test

An appliance for use in residual stress analysis of a component under test (CUT), the appliance comprising:

• a motion platform having two or more mutually orthogonal axes of motion;
• a drive mechanism for each motion axis coupled to a control system;
• a machining tool coupled to the control system, wherein the tool is configured to machine a plurality of light cuts in an internal surface of a component under test (CUT) without introducing additional stress from a machining process, so that residual stress in an area proximate to a machined feature of the component under test is interrupted from a bulk of the CUT, thereby preparing the area proximate to the machined feature for locating a sensor configured to measure strain or displacement of the area proximate to the machined feature of the component under test in response to the residual stress being interrupted from the bulk of the CUT;
• an adjustable mount for positioning the machining tool;
• an image sensor having a viewing area proximate to a cutting location of the machining tool;
• and
• wherein the control system includes a processor and interface enabling the entry and execution of operational instructions and parameters, a display of images, and the calculation and storage of measured and derived information.
