Tolerance Designer

CQM Tolerance Designer helps engineers predict the impact of tolerances on product designs and assess whether a design meets its specifications. The tool helps determine the tolerances required for underlying component parameters to ensure optimal end-product performance.

Why CQM Tolerance Designer?

In manufacturing, variation in raw materials, components, and processes is inevitable. These variations are expressed as tolerances. CQM Tolerance Designer helps you:

Predict whether a design will meet its specified requirements
Determine optimal tolerances for modules, components, and processes throughout the V-model
Avoid specifications that are either too tight or too loose, helping control costs without compromising quality
Identify critical parameters and dimensions for technical drawings

CQM Tolerance Designer can be used across a wide range of applications, from injection-molded products and process industries to high-tech product development.

How does CQM Tolerance Designer work?

The tool uses transfer functions: mathematical models that describe the relationship between end-product performance and component parameters. These transfer functions are typically based on physical knowledge, experiments using Design of Experiments (DoE), or regression models of varying complexity based on observational data.

With its intuitive interface, CQM Tolerance Designer offers powerful functionality, including:

Support for a wide range of transfer functions and tolerances with statistical distributions
Statistical metrics (Cp, Cpk) and histograms of end-product performance
Interactive optimization using sliders for input parameters, with real-time updates
Impact analysis of parameters and their tolerances on end-product quality

Who is CQM Tolerance Designer for?

The tool is designed for professionals in industries such as high-tech, food, and process manufacturing. It is used by professionals including design engineers, mechanical engineers, product developers, and process engineers.

When should you use CQM Tolerance Designer?

When developing a new product
When making changes to an existing design
When changing suppliers

The tool also helps retain and transfer knowledge. Completed tolerance analyses, including transfer functions and tolerances, are stored in a case file that can be incorporated into the Technical Product Documentation (TPD).

Easy to use

CQM Tolerance Designer was designed with engineers in mind: practical, intuitive, and ready to use. The tool is provided through an annual named-user license, and its results can be used directly in presentations and decision-making.
