Proper Part Dimensioning in Build to Print Stamping Applications

In order to properly manufacture a custom metal-stamped component, Rotation Engineering needs to have an acceptable drawing that describes all of the product’s key shapes and features. A complete dimensioned print includes measurements and required tolerances, highlighting both critical and non-critical design elements.

An Overview of Print Dimensioning

The goal of a properly dimensioned print is to ensure the end product’s full functionality and compatibility, while also maintaining manufacturing consistency. Furthermore, a detailed part blueprint gives your metal stamping provider a guide so they can create an optimized production plan and perform engineering improvements if necessary.

For these reasons, proper dimensioning and tolerancing is perhaps the most critical initial step in the design for manufacturability (DFM) process for build to print applications.

Critical vs. Non-Critical Design Features in Print Dimensioning

Every custom metal-stamped part or assembly is designed with a specific functionality in mind for the end product. Some design features and tolerances are absolutely critical to the product’s functionality while others are not.

In the case of precision manufacturing, critical design features generally need to adhere to tighter tolerances and higher degrees of accuracy. A properly dimensioned print details all of the critical design features so that your manufacturer can produce your products with the utmost quality, consistency, and efficiency.

An Example of Critical and Non-Critical Dimensional Tolerancing

As an example – a dimensioned print for a custom-stamped metal bracket might illustrate numerous different bends featured throughout the part. Some bends may be critical design features that require tight tolerances.

However, other bends in the bracket may be less critical to the part’s functionality, or purely aesthetic. For those features, precision tolerances are not required. A properly dimensioned print will highlight which design features are functionally non-critical to streamline the manufacturing process.

At Rotation, we can save time and money through engineering enhancements aimed at optimizing the manufacturability of your products.

What Details Should a Dimensional Print Include?

A complete dimensional print not only details the tolerances and dimensions of the product. When required, it will also include additional design and engineering information, including:

  • Full assembly details: hardware locations, bends, welds, etc.
  • Functionally critical vs. non-critical design features.
  • Required material type, specification, and thicknesses.
  • Custom finishing requirements and associated specifications.
