Abstract

Abstract--- Walking Line Assembly (WLA) is performed by positioning workers along assembly line at every process stations in the production line as and when required. This has benefitted the assembly and fabrication industry without the need for a dedicated layout, thereby leading to reduction in the fixed costs. This paper describes the application of WLA in prototype fabrication of yoke sub-assembly and details its effectiveness. The WLA procedure is described in two parts: Part I presents the technical aspects and challenges involved in development and fabrication of engine mount yoke tube assembly for a civil aircraft. This highlights the importance and significance of the parts, brackets, dimensional robustness, procedures, assembly, jigs and fixtures associated and the necessity of categorizing it as Class-1. Activities representing reverse engineering process and fabrication of yoke tube are detailed comprehensively. Part II presents the WLA model adopted for this assembly. Comparison with conventional methods and layouts of fixed and walking line assembly are done. Further, WLA is modified with a common stage set on every process where the expected capability of the task in shop floor is brought out in consensus with the operational demand and standards. This is achieved with very little disturbance to the existing aircraft fixed line fabrication set up. This model has given encouraging results by expediting the processes and provides an ideal option for building of prototypes in development stage of an aircraft project. Keywords--- Engine Mount Assembly, Model Effectiveness, Reverse Engineering, Walking Line Assembly
