... film strain gauge array that is suitable for in situ measuring of temperatures and strains in manufacturing processes was designed and fabricated for testing in the vertical end milling process. Time- and spatial-resolved signals were obtained during the milling process. The signals were decomposed...

... of residual stress measurement are very time consuming and expensive. In this paper we presents a wet etching approach to obtain strain as a function of slot depth introduced in the subsurface. The strain readings were collected from a strain gauge mounted on the specimen surface near the slot edge...

...), which produces blanket depositions of films and coatings, with ultrafast laser micromachining (a subtractive process) to produce functional sensors. Microheaters and strain gauges have been successfully fabricated in this work to demonstrate the feasibility and advantages of the proposed technique...

... surface is instrumented with strain gauges. Relative to previous sensor designs, this sensor offers reduced disturbance of the frictional interaction between the tool and the workpiece. A proof-of-concept prototype has been constructed and tested in a laboratory test apparatus. The results of testing...
