PRELIMINARY RESULTS FOR AN INSTRUCTION DESIGN PROCEDURE IN AERONAUTICAL MANUFACTURING

In the field of aeronautical manufacturing, compliance with strict quality standards is essential for ensuring the safety and reliability of aircrafts. Within this demanding environment, operators engaged in assembly tasks are bound to follow meticulous, standardized procedures. Under these conditions, providing clear and effective assembly instructions to the workforce becomes paramount for both meeting quality requirements and boosting production efficiency. With the aim of refining the existing protocols, this paper introduces a structured proposal to assembly instruction design. The contribution of this work is twofold. Primarily, by introducing a taxonomy of Assembly Features (AFs) it provides the designer with a valuable tool for identifying task-specific instruction content. Secondly, it offers a systematic framework for evaluating the most appropriate format for delivering task-specific instructions. The framework is based on two assessment dimensions: (i) the Representation Ability (RA), which gauges the format's capability in conveying the required AFs; and (ii) the Processing Efficiency (PE), which assesses the immediacy and clarity with which the format presents this information. Overall, this work introduces a structured, step-by-step approach to support designers, aiding them to strike a balance between the efficacy of information representation and the efficiency of its processing. To enhance its clarity and showcase its real-world utility, the approach is elucidated through applied examples focused on the assembly of a mechanical component.
