CMSC 2019 PRESENTATION - Towards right-sized limits: rationalizing build tolerances In activities such as aerospace tool building the tracker operator is often faced with a demand to build to extremely tight, perhaps even impossible, tolerances. Although there are many unknowns it is possible to estimate the uncertainties associated... Citation: KARL CHRISTENSEN, JOANCLAIRE CORBETT AND ROBERT FLYNN; FLYNN AT ELECTROIMPACT, INC.

CMSC 2019 PRESENTATION - Tracker Kinematics and Uncertainty using Quaternions Kinematic modeling of trackers has typically used Euclidean vectors. Measurement uncertainty is estimated with Monte Carlo methods or linear propagation of errors, operating on the parameter for range, horizontal, and vertical angles. A downside of this...

CMSC 2019 PRESENTATION - Point Density and Fitting Algorithm Interaction in Part Profile Scanning One of the major differences between tactile and optical profile scanning methods is the sampled point density. Not only do optical methods collect many more points, the point spacing (which is almost uniform in tactile measurement) can be highly variable... Citation: Farid Javidpour, Edward Morse
