RISDesign Evaluation of Sheet Metal Joints for Dimensional Integrity
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The design of joints between parts is one of the most critical issues in the design of sheet metal assemblies. This paper presents a new part-to-part joint design evaluation index developed ...
Sensor Optimization for Fault Diagnosis in Multi-Fixture Assembly Systems With Distributed Sensing
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Sensing for the system-wide diagnosis of dimensional faults in multi-fixture sheet metal assembly presents significant issues of complexity due to the number of levels of assembly and the number ...
Fixture Failure Diagnosis for Autobody Assembly Using Pattern Recognition
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, a fault diagnostic method is proposed for autobody assembly fixtures. This method uses measurement data to detect and isolate dimensional faults of part caused by fixture. The ...
Fixture Failure Diagnosis for Sheet Metal Assembly with Consideration of Measurement Noise
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper expands previously developed assembly fixture fault diagnosis methodology (Ceglarek and Shi, 1996) by considering the impact of measurement noise on the diagnostic results. The proposed ...
Process Yield Improvement Through Optimum Design of Fixture Layouts in 3D Multistation Assembly Systems
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Fixtures control the positions and orientations of parts in an assembly process. Inaccuracies of fixture locators or nonoptimal fixture layouts can result in the deviation of a workpiece from ...
A Knowledge-Based Diagnostic Approach for the Launch of the Auto-Body Assembly Process
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper is the first attempt to implement a knowledge-based diagnostic approach for the auto-body assembly process launch. This approach enables quick detection and localization of assembly ...
Dimensional Fault Diagnosis for Compliant Beam Structure Assemblies
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A model-based diagnostic methodology is proposed for the dimensional fault diagnosis of compliant beam structures in automotive or aerospace assembly processes. In the diagnosis procedure, the ...
Modeling and Optimization of End Effector Layout for Handling Compliant Sheet Metal Parts
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Material handling of compliant parts is one of the most critical and underresearched problems in the sheet metal stamping industry. The fundamental shortcoming of currently studied material ...
Adjusted Least Squares Approach for Diagnosis of Ill-Conditioned Compliant Assemblies
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Least squares (LS) estimation has been extensively used for parameter identification and model-based diagnosis. However, if ill-conditioning is present, the LS estimation approach tends to generate ...
A Dexterous Part-Holding Model for Handling Compliant Sheet Metal Parts
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Material handling of compliant sheet metal parts significantly impacts both part dimensional quality and production rate in the stamping industry. This paper advances previously developed material ...
