Handling features in assembly: Integrating manufacturing considerations early in design discussions

Abstract

The early stages of product design are critical for incorporating manufacturing perspectives. Recognizing the significance of assembly in discrete product manufacturing, the study emphasizes the need to consider the intricacies of assembly early in the design stages. While existing research has addressed assembly features, especially for insertion, this study focuses on handling features, seeking to bridge the gap in their comprehensive representation within the product model. Based on a relational analysis, product characteristics relevant for handling were identified and represented by using a modelling strategy that facilitates their timely addition to the product model. A case study was developed to demonstrate its application. The main contributions of this work comprise an extensive list of product characteristics related to handling processes, a proposal for integrating these characteristics into the product model, and a collaborative way to define product features during product design. Future research directions point to the establishment of a model-based definition for assembly processes, paving the way for enhanced cross-disciplinary communication in the fields of product design and assembly planning.
