In a Multi-operational Machining Process (MMP), final product variation is an accumulation, or stack-up of variations generated at all the manufacturing operations. In this paper, variation transmission in the MMP is analyzed by relating part variations to operational errors from machine tools, fixtures and datums. At each operation, total part variation is separated into several components cor...

This work focuses on a robot’s task of predicting the navigation intent of human teammates using Inverse Reinforcement Learning. The purpose of this study is to introduce the On-the-fly Maximum Margin Planner (OTF-MMP) method which estimates a predictive navigation model in real-time from the observed actions of a human teammate. We include an experiment to test the predictive ability of the me...
