Effects of machining system parameters and dynamics on quality of high-speed milling
(University of Missouri--Columbia, 2013)
mathematical force models including the effect of the helix angle are presented for an end-milling process. The linear force model includes cutting-edge coefficients. The cutting force coefficients are determined for an end-milling process using two methods...
Robust control design for a proportional valve with backlash compensation
(University of Missouri--Columbia, 2013)
uncertainties. Thus, unexpected changes in the stability can be exhibited and can lead these systems to become unstable exhibit oscillatory behavior. Engineers have been trying to develop nonlinear mathematical models to be able to predict whether or not a...
Chatter detection and prevention in high-speed milling
(University of Missouri--Columbia, 2011)
In this work, two separate mathematical models, a traditional and new model, are presented for an end-milling process. The traditional model assumes circular tool motion, while the new model accounts for trochoidal tool motion resulting from...
Effect of chip thickness, sub-critical bifurcations and process parameters in high-speed milling
(University of Missouri--Columbia, 2010)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] The main focus of the current research is to experimentally and numerically investigate of subcritical bifurcations in milling accounting for actual ...
Investigation of the performance of an automatic arterial oxygen controller
(University of Missouri--Columbia, 2018)
trial at the NICU of the MU Women's and Children's Hospital. The crossover design was used for the clinical trial to allow within-subject comparison and to eliminate interpatient variability. Two human subjects, with two different target ranges of SpO2...
A method of frequency domain error modeling to predict the probability of stability and performance of dynamic systems with parametric uncertainty
(University of Missouri--Columbia, 2012)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] In this work a method is developed for modeling frequency domain error in dynamic systems with parametric uncertainty. Within any mass-manufactured ...
