Dimensional analysis to reduce variation and improve product quality

Vis VSA is a powerful dimensional analysis tool used to simulate manufacturing and assembly processes and predict the amounts and causes of variation. Vis VSA can help reduce the negative impact of variation on product dimensional quality, cost and time to market. Since Vis VSA's foundation lies within Teamcenter® Visualization, it also extensively leverages the digital prototyping and visualization capabilities of Vis Mockup, UGS' powerful real-time visualization and digital prototyping solution.

Vis VSA's business value

Optimize product and process: Vis VSA allows users to identify dimensional problems early in the design cycle, thereby avoiding assembly build and quality issues due to excessive variation. With this solution, design flaws can be caught before committing to tooling. Identify critical dimensions: Vis VSA identifies critical dimensional tolerances and assembly processes that are key contributors to variation. These areas have a significant impact on product quality and therefore warrant careful monitoring. Reduce costs: Vis VSA reduces cost by improving product quality and accelerating time-to-market. In addition, manufacturing costs can be reduced by maximizing allowable part tolerances, while still controlling critical assembly dimensional specifications. Controlling these dimensional characteristics helps minimize scrap, rework and warranty defects. With Vis VSA product quality is significantly improved by insuring that parts fit and work together properly – the first time.

Features and benefits

Vis VSA is one of several interoperable tools in the Teamcenter Quality solution. With Vis VSA, manufacturers can:

• Identify tolerances and assembly processes that contribute to variation and perform quick “what-if” analyses to optimize tolerances, design and the assembly process.
• Create feature-based models before or after geometry is available. Creating models prior to geometry helps drive the design before parts are made or tooling is cut.
• Leverage the most powerful variation assembly constraint engine in the world.
• Perform comprehensive statistical or simulated worst-case analyses
• Incorporate component flexibility through linking with finite element analysis results.
• Display a variety of graphical reports tied to 3D geometry
• Represent tolerances with different types of distributions.
• Extend the analysis to support user-defined equations such as gear backlash, pressure, imbalance, etc.
• Capture knowledge and reuse models; morph features to new geometry
