Tolerance Management to support design and to predict the in-service product functionality

Tuesday 29 October 2019   14:00 - 17:30   Workshop | Language: English

Ensuring the reliability of hi-tech products can only be achieved by design engineering processes that properly consider the products’ geometric and dimensional deviations.
This level of detail is vital today to achieve the competitive advantage resulting from reduced re-design cycles, cost-savings at the prototype stage, minimization of nonconformities, more cost-effective manufacturing processes, and reduced time-to-market. Truly robust design is engineered through the integrated management of tolerances. This involves tolerance propagation analysis along with a geometric and dimensional description that complies with the latest international standards (ISO-GPS and ASME/GD&T). These enable the creation of complete sets of tolerance parameters that can be uniformly interpreted to predict the in-service product functionality.

  • The use of the appropriate tolerance management methodology at the design stage is a powerful tool for studying the impact of possible dimensional variations in parts.
  • Product malfunctioning is affected by changes in the tolerances of the design resulting from the precision manufacturing of each component.
  • The same model is used to verify the impact of metrological measurements to support the process of approving quality exceptions (non-conformity management).
  • In addition, tolerance management can study product life, which often changes during use due to small dimensional variations created by different phenomena (e.g. wearing, thermal dilatation, etc.).

Target Audience: Product designers, Design managers, Mechanical engineers, Quality operators and analysts, and Professionals who want to address the new challenges in product life cycle assessment.

Topics: Introduction to dimensional management, Using tolerance management to predict malfunction, GD&T: The basic concepts and the role of the standards in design, Real applications and experience from industrial partners, Dimensional quality control.

PRELIMINARY AGENDA

14.00 - 14.20

Dimensional Management

Introduction: engineering methodology combined with computer-simulation tools used to improve quality and reduce cost. The objective is to create a design and process that "absorbs" as much variation as possible without affecting the function of the product.
