Tooling adjustment strategy for acceptable product quality in assembly processes
This paper develops an approach to minimize the number of process tooling adjustments and deliver an acceptable fraction of non-conforming products based on given product quality specification limits in assembly processes. A linear model is developed to describe the relationships between product quality and process tooling locating positions. Based on the model, the process mean shifts of tooli...
متن کاملFeedforward Control of Multistage Assembly Processes Using Programmable Tooling
The combination of feedforward control and programmable tooling has emerged as a promising method to reduce product variation in multistage manufacturing systems. Feedforward control allows compensation of deviations on a part-by-part basis using programmable tooling. This paper addresses the problem of designing an optimal feedforward control law that improves quality. The controller design in...
متن کاملMulti-model based real-time final product quality control strategy for batch processes
A novel real-time final product quality control strategy for batch operations is presented. Quality control is achieved by periodically predicting the final product quality and adjusting process variables at prespecified decision points. This data-driven methodology employs multiple models, one for each decision point, to capture the time-varying relationships. Thesemodels combine real-time bat...
متن کاملIntegration of Energy Information for Product Assembly and Logistics Processes
This paper presents an on-going effort at NIST to model the energy information in assembly and logistics processes as a part of a larger sustainability improvement goal. Energy information comprises energy input, baseline energy consumption, and energy performance. An information model in this paper is developed for enabling integration of energy information in assembly and logistics processes....
متن کاملSimulation and analysis of assembly processes considering compliant, non-ideal parts and tooling variations
Variations in parts and tooling are a major problem in automobile body assembly processes. Those discrepancies adversely affect body assembly quality, functionality, cost and time-to-market. Variation simulation analysis has been used in the design stage to predict such uncertainties, but variation analysis based on rigid body assumptions usually yields over-estimates of the assembly variations...
