The recent introduction of low‐cost vision sensors has greatly increased the range of applications for vision. Within the arena of automated assembly there are a number of tasks that vision is suited to and these are outlined. Also the idea of distributing vision throughout the assembly process together with networking via Ethernet is examined.

The article aims to highlight the advantages of using vision‐based code readers to ensure part traceability.

With the implementation of legislation and regulations within a number of industries, (e.g. aerospace, automotive etc.) manufacturers are under increasing pressure to produce compliant parts and ensure complete product traceability. To accommodate these industry changes, 2D codes are being marked directly onto parts.

There are seven principle factors to consider while implementing direct part marking identification, thus ensuring that product traceability is achieved and effectively monitored using vision‐based code readers.

Direct part marking can be achieved on a variety of product surfaces, and is therefore attractive to a vast range of manufactured products. With ever‐changing developments in technology, new markets are being continually opened up to the benefits of product traceability.

Achieving compliant production not only improves overall productivity and reduces operating costs, but it also enhances the chance of contract renegotiation and avoids costly and possible reputation‐damaging product recalls.
