• CETOL 6σ is a software designed for designers and managers of production and quality, specifically designed to identify and eliminate problems arising from the propagation of intrinsic errors in all production processes.
  • CETOL 6σ it allows the analysis of the propagation of tolerances inside assembled products, in rapid and intuitive way, directly working inside the environment CAD.



The perfect integration with the solid modeler allows to define the interactions among the components in few clicks inside the graphic environment. Once defined, the contacts are automatically managed by the software, in order to reproduce multiple operating configurations of the same device. Since CETOL 6σ uses a complex mathematical formulation of the surfaces, it is able to update the contact points (and therefore the interactions between the components) in real time, regardless of the complexity of the geometries. This allows to visualize by means of animation in CAD environment the effects of the variations of the single quotas involved in the study. The Derivative Based approach with which CETOL 6σ solves the statistical combination of tolerances, allows to reach the results in a few moments, unlike other computationally much more expensive methods (Monte Carlo method).

The post-processor of CETOL 6σ was designed to highlight in few steps the presence of problems with respect to functional shares. When it is necessary to intervene to reduce production waste, optimal corrective interventions (more effective, at lower cost) can be identified by combining together the information returned from the advanced graphical output of CETOL 6σ. In particular, for each functional portion, it is possible to view both the expected distribution and the influence of the individual parts of the components on any non-compliant result. The work ends with the automatic generation of a detailed descriptive report, useful both to the product designer and to the quality controller.

CETOL 6σ is therefore a powerful tool of Concurrent Engineering that allows to save both in the design phase and on the prototyping, reducing waste to a minimum, in an increasingly widespread view of Lean Thinking.
