摘要
There is included in apparatus for checking a structural component for intrinsic stresses by attaching strain gage means to a surface measuring area of the component, cutting an annular groove into the component around the area, measuring through terminal leads extending from the strain gage means the change in electrical response of the strain gage means, due to the cutting of successive layers of material out of the groove, as indicative of the intrinsic stress existing prior thereto, and measuring the depth of the layer of removed material or the corresponding depth of the groove after each incremental cut, a crown boring tool for machining the annular groove around the measuring area, the tool having a shaft hollow throughout and being mounted in a hollow boring spindle whereby the terminal leads of the strain gage means attached to the measuring area are extensible through the tool and the hollow spindle.
