In Laser Metal Deposition (LMD), a blown powder metal additive manufacturing process, functional metal parts are fabricated in a layer-by-layer fashion. In addition to the inlayer dynamics, which describe how the process evolves within a given layer, the additivefabrication property of LMD creates a second set of dynamics which describe how the process(More)
Bearing systems and harmonic drives in robots introduce complex kinematic errors which result in joint kinematic errors that reduce the accuracy of their manipulators. Typical calibration methods do not consider these complex errors, thus, limiting post calibration performance. In this paper, a method of modeling and calibrating robot kinematic errors by(More)
