Critical Parameter Management Platform

Managing the impacts of Geometrical Dimensioning and Tolerancing (GD&T) decisions on fit for assembly and functionality (for example, forces, gaps, or kinematics) is highly complex for products with many tolerancing stackups. To avoid costly quality problems, changes to GD&T parameter values that are most critical to meeting requirements must be quickly assessed across all impacted stacks to identify any unacceptable failure rates.

Adding to complexity, these products typically involve teams of mechanical designers. A parameter change critical to meeting a requirement made by one designer can easily adversely impact stackups and failure rates of requirements managed by others. This can easily lead to delays in prototyping, tooling, and production — potentially costing millions of dollars.

Typically, teams rely on spreadsheets containing all of the stackup calculations across a product, or family of products. The spreadsheets can include hundreds of stackups and tabs, making them time consuming to set up and prone to human errors.

Enventive 360 (E360) uniquely meets the challenges of managing mechanical variation for products with numerous tolerancing stackups — often totaling well into the hundreds or thousands. As a web-based, collaborative platform, E360 organizes and updates tolerance analysis results for all affected 1D, 2D, and 3D stacks in seconds, providing 100% confidence that nothing is missed.

Built on Enventive’s industry leading variational analysis engine, E360 is the only available tolerance analysis software that guides designers to focus on the critical design parameters contributing to failure rates of the most important requirements for product fit and functionality.

E360 uniquely ranks contributors across all stackups based on: 1) the number of stacks affected, 2) the severity of a failure for each affected stack, and 3) the sensitivities of contributor impacts on each stack.

With E360, designers can rapidly identify critical parameters, run what‑if simulations to evaluate impacts across all stacks within seconds, and then manage the parameters throughout design, prototyping, and production.

The results? Designers can identify and focus on the most important contributing parameters, slashing time and effort to improve quality, reduce manufacturing costs, and improve product performance. And because E360 is analyzing failure rates concurrently for all stackups using up-to-date values, designers and management have far greater confidence in their decisions.

E360’s focus on critical parameters further enables Quality Assurance (QA) and Production teams to confidently create control plans that result in more efficient inspection and manufacturing of parts that meet specifications.

“Enventive 360 provides a comprehensive view of your design projects with unmatched abilities to identify, organize, rank, analyze, and manage critical parameters, offering a unique platform for improving product quality and reducing manufacturing costs.”

• Cloud and browser access – Hosted cloud solution with a web browser interface secures data and enables team collaboration.
• Import 3D, 2D, and 1D tolerancing stackups – Import and combine stackup models from 3D models created with Enventive’s 3D&T software, 2D models created in Enventive Concept, or 1D hand stack contributor files created in spreadsheets.
• Revision control / change management – Track all parameter changes with public and private publishing, including merging of changes from multiple users, to support team productivity and traceability of change histories.
• Review and manage all stackups – Visually organize and navigate all stackups quickly to manage status and parameter values.
• Individual stackup details – Immediately view any individual stackup for a detailed report and to make parameter changes to analyze impacts on failure rates of requirements.
• Analyze risks – Quickly pinpoint and manage critical design parameters.
• What-if analyze – Rapidly what-if analyze, within seconds, the impacts of design parameter changes on failure rates of product requirements across all stackups. Analysis can assess the effects of changes to functional limits, failure severities, target statistical Cp values, nominal values, and tolerancing values. E360 calculates stackup results using worst case or statistical RSS methods.
