Outsource Tolerance Stackup Analysis Services

Tolerance Stackup Analysis Services

Shorten product development cycles with expert product tolerance stackup analysis services at cost-effective prices

When a design model is under the manufacturing phase, it faces a lot of manufacturing limitations and the teams need to accommodate certain tolerances or acceptable degrees of variation. Tolerance analysis allows the product engineers and engineering companies to understand how geometric tolerance stackup and their dimensional variations have an impact on design quality and its manufacturing ability. A careful analysis of the contributing tolerances enables the engineers to modify them for achieving high quality and improved processes.

Due to the complex and specialized nature of the field, most companies choose to outsource the tolerance stackup analysis services to experts. Flatworld's dedicated wing of engineers and testers have handled more than 3000 projects and have proven experience in this domain, making them an ideal choice for outsourcing tolerance stackup analysis services.

Being an experienced tolerance stackup analysis services providing company, we leverage the use of various tools and technologies to accurately determine the tolerance stackup and allow better design quality and manufacturability. Combining the strength of tolerance analysis with geometric dimensioning and tolerancing (GD&T), we fully ensure that the company's designs are compliant with the relevant ASME and ISO standards.

3D Tolerance Stackup Analysis Services We Offer

Some of our key offerings under tolerance stackup analysis include the following methodologies and solutions:

  • Worst-case Scenario Analysis: Many product manufacturing organizations undertake a conservative approach while developing prototypes. In such cases, we follow the traditional stackup calculation method of a worst-case scenario where we set all the tolerances at their maximum limits.
  • Statistical Variation Analysis: We also have experts in our team for statistical variation analysis that uses the Monte Carlo method to determine the percentage of the product parts that will be out of the given tolerance specification limits. We calculate the nominal output using statistical probabilities by modeling each component's statistical distribution and then adding together these distributions to predict the assembly measurement distribution.
  • RSS (Root Sum Square) Analysis: An alternative method of statistical variation, RSS is a three-dimensional stackup analysis that we use to determine the overall variation. We use the data available about the part(s) variation and set their tolerances accordingly to create designs that offer better reliability given the expected part variation. Under this, we also leverage the other two types of analysis: the modified RSS and Process Centering RSS as per the specific requirements of the project.
  • Integration of Tolerance Optimization Software: We understand your project requirements and assess the best and most-suited tolerance optimizer software as per your needs. We select and integrate the most optimal third-party analysis tools to attain efficient tolerance analysis for their product designs.
  • Documentation and Report Generation for Tolerance Stackup Analysis: We provide single-source documentation and create robust reports of our tolerance stackup analysis findings, enabling improved decision-making. Developing GD&T drawings as per ASME Y 14.5 / ISO standards, specifying inspection dimensions for quality control, creating models prior to production and assembly, generating reports for automatic statistical, sensitivity analysis, and SPC, etc., are all the varied services we offer.
