A Framework for Effective Implementation of Process Failure Modes and Effects Analysis with Control Plans to Mitigate Process, Discrete Manufacturing and Service Industries, Using Aerospace Standard Best Practices

GITAM School of Technology-Mani Rathinam Rajamani, Eshwaraiah Punna
Published 2019-10-11 by SAE International in United States
In Today’s World, Every Manufacturing and Service Industry aims in providing the Highest Quality of Products and Service at the lowest Competitive Cost and timely delivery to its Customers. The Discrete Aerospace Manufacturing and Assembly industry is taking initiatives to implement the Process Failure Modes and Effects Analysis (PFMEA) tool for its critical Aerospace Manufacturing and Assembly suppliers, by implementing Aerospace Standards, in an effort to create a synergy between the End user customers, Original Equipment manufacturers and the suppliers, for ensuring increased safety, quality, reliability for the Aircraft parts and components produced by them. The main aim is to use this concept as a Process Risk Management tool for Identification, Assessment, Mitigation, Control and Prevention of risks associated with Designs and Manufacturing. This method is quite different from conventional FMEA methodology as it focuses on an integrated approach of linking the process flow diagram, followed by a PFMEA again linked with a Control plan to identify and implement controls for measuring and monitoring the process risks. This can identify the manufacturing system’s area of…

Simulation of Aircraft Assembly via ASRP Software

Airbus-Elodie Bonhomme
Peter the Great St. Petersburg Polytechnic University-Nadezhda Zaitseva, Tatiana Pogarskaia, Olga Minevich, Julia Shinder
Published 2019-09-16 by SAE International in United States
ASRP (Assembly Simulation of Riveting Process) software is a special tool for assembly process modelling for large scale airframe parts. On the base of variation simulation, ASRP provides a convenient way to analyze, verify and optimize the arrangement of temporary fasteners. During the assembly of airframe certain criteria on residual gap between parts must be fulfilled. The numerical approach implemented in ASRP allows to evaluate the quality of contact on every stage of assembly process and solve verification and optimization problems for temporary fastener patterns. The paper is devoted to description of several specialized approaches that combine statistical analysis of measured data and numerical simulation using high-performance computing for optimization of fastener patterns, calculation of forces in fasteners needed to close initial gaps, and identification of hazardous areas in junction regions via ASRP software.
