Laser Deposition Cladding On-Line Inspection Using 3-D Scanner
Laser deposition directly deposits metal cladding to fabricate and repair components. In
order to finish the fabrication or repair, 3-D shape of the deposition needs to be inspected, and
thus it can be determined if it has sufficient cladding to fabricate a part after deposition process.
In the present hybrid system in the Laser Aided Manufacturing Lab (LAMP) at the University of
Missouri - Rolla, a CMM system is used to do the inspection. A CMM requires point-by-point
contact, which is time consuming and difficult to plan for an irregular deposition geometry. Also,
the CMM is a separate device, which requires removal of the part from the hybrid system, which
can induce fixture errors. The 3-D scanner is a non-contact tool to measure the 3-D shape of laser
deposition cladding which is fast and accurate. In this paper, A prototype non-contact 3-D
scanner approach has been implemented to inspect the free-form and complex parts built by laser
deposition. Registration of the measured model and 3-D CAD model allows
the comparison between the two models. It enables us to determine if the deposition is sufficient
before machining.Mechanical Engineerin
