Variation reduction of a closed-loop precision ceramic micromachining process
… dimension limits are scrapped, so the variance reduction directly impacts immediate and downstream process yields. An alternative approach is proposed using electrostrictive actuators in a closed control loop to deform the bar during lap processing. The closed-loop lapping (CLL) process …

New Strategic and Dynamic Variation Reduction Techniques for Assembly Lines
Variation is inevitable in any process, so it has to be dealt with effectively and economically. Reducing variation can be achieved in assembly lines strategically and dynamically. Implementing both the strategic and dynamic variation reduction techniques is expected to lead to further reduction in …

System variation analysis of MIG welded aluminum structural frames
Variation reduction techniques are developed which explore an entire system for improved quality, rather than a single manufacturing operation. This system-level modeling approach is explored with an example of a complex assembly of aluminum extrusions and castings welded into a structural frame. …

Temporal Comparisons on the Genetic Variation of the Dusky Gopher Frog (Lithobates sevosus)
… a consequence of isolation and population size reduction. However, the temporal changes in genetic variation are not known. Therefore, my objectives were to (1) determine temporal trends in population genetic variation and implications for long-term viability of L. sevosus and (2) estimate …

Manufacturing Process Design and Control Based on Error Equivalence Methodology
… error sources result in identical deviation and variation patterns on part features. This could have dual effects on process variation reduction: it significantly increases the complexity of root cause diagnosis in process control, and provides an opportunity to use one error source as based …
-
Alternate methodology for generation and use of key characteristics
Hardware variation reduction is an issue of paramount importance to manufacturing companies in their efforts to reduce cycle time and manufacturing costs. Hardware variation leads to increased rework, and decreased levels of customer satisfaction. The Boeing Company, the leading manufacturer of …
