What are jigs and templates used for in assembly methods?

Jigs and templates are essential tools used in assembly methods primarily to facilitate accurate assembly and alignment. They are designed to hold pieces in the correct position during the assembly process, ensuring that components are correctly aligned and secured, which ultimately leads to improved precision and consistency in manufacturing.

By using jigs, workers can efficiently repeat processes without excessive measuring or trial and error, significantly reducing production time and errors. Templates serve a similar function, often providing a guide or pattern for cutting or positioning components. This accuracy is critical in industrial settings where even slight misalignments can lead to functional issues in the final product.

In contrast, enhancing aesthetic design, joining materials using heat, or calculating material volume do not relate directly to the primary function of jigs and templates. These tools are specifically tailored to improve the assembly process rather than focusing on aesthetic aspects, material joining techniques, or volumetric calculations.
