The material of a part or component has a decisive impact on the complexity and laboriousness of assembly process. Thus, solid, fragile and flexible parts and components are all handled in a different way. The present paper classifies some of the most common types of materials parts are usually made of, while also analyzing their impact on the assembly process. In mechanical engineering, solid parts are most often used, given that these do not require special measures in known assembly orientation and handling techniques. However, such solid materials pose several challenges as well, and this mainly due to their several specific shapes, which means a specific problem in gripping and especially in their orientation during the assembly process. In this regard, the paper also addresses with one of the most important and assembly-troublesome properties of these solid parts, which the degree of symmetry. The degree of symmetry of solid parts has a direct impact on the complexity and laboriousness of their orientation in assembly. The last part of the paper focuses on the theoretical basis for the calculation of complexity and laboriousness in the assembly of parts.
