Decuna worked together with a counterpart responsible for mechanics developing an automated storage system for an automotive seat supplier.

An automated storage and retrieval machine and a buffer for the products were automated.

The system saves an important amount of storage space and allows our customer to meet not only "Just in Time" requirements, but also "Just in Sequence" (delivering the sequence that the OEM is going to build in the production line).

Decuna adapts old equipment and machinery with modern CNCs that improve significantly productivity and reduce downtime and maintenance. Such examples can be found in grinding and cutting machines for several industries.

If the mechanical part of the tooling is in good condition, this investment pays off in a short period of time and implies savings compared to installing brand new machinery.

The Excello grinding machine does six grinding operations in the halfshaft production process.

This operation needs an accurate control to perform the task correctly, and therefore it has been coupled to a CNC processing unit. Decuna developed the software that allows the machines to work together.

 
 
Decuna integrated the data retrieval of statistic process control data (assembly control parameters and tolerances) in seven halfshaft assembly cells with the ERP at the customer's site.
There were controlled four operations in each machine. The information was distributed and stored in an Oracle database with Decuna applications.
Some PanelPCs were installed to monitorize the process and allow user interaction

Decuna developed a system with applied computer vision to check if the grinding operation was performed satisfactorily or not in the gear cages of the halfshafts.

The system has to be able to detect this in less that two seconds, because of strict operation cycle requirements. Nevertheless, the system could meet customer requirements.
