Ease of use


The interaction interface of TADM software is rather intuitively simple and common – it’s Microsoft Excel. Studies have found that most design engineers use Excel to perform tolerance stack-up & analysis. So, TADM takes advantage of a tool such as Excel, that the users already familiar with.

Sophistication of Database System

At the core of this system lies a sophisticated database to warehouse complex application logic, volumes of part records and tolerance analysis information. This enforces to standardize and centralize design requirements, inspection data and tolerance analysis information into one application, one storehouse with one version of truth. Such bold feature helps eliminate confusion,  hours to maintain and update multitude of stacks, and shorten design cycle time when as-built inspection data can be incorporated into the design process.

Automatic Tolerance Stacks Updates


One of the major benefits of this system is that, when changes are made to the parts design, the system can automatically update tolerance stacks created within this system. This feature can alone eliminate hundreds of hours of manual work. Moreover, it reduces the chance to make mistakes by reducing manual intervention.

Incorporation of Full GD&T Requirements into Tolerance Analysis

The system provides GD&T capabilities into its tolerance analysis application. The predefined rules and formulas to handle GD&T based tolerance analysis are stored in the database. The application is dynamic enough to automatically apply these rules and formulas to the basic dimensions and geometric tolerances in conjunction with associated GD&T requirements if they are applied.

Advanced Analyses


TADM-System is far more than a standard tolerance analysis solution. The application provides advanced and powerful tools to fine-tune Tolerance Analysis for higher accuracy and better cost-effectiveness. Some of these advanced tools are as follows:

  • Scenario Analysis allows the engineers to realize possible impacts on the current stacks and/or all existing stacks if changes are made to the design
  • Sensitivity Analysis allows the user to quickly recognize how each component/part can have impacts on other components /parts on the same tolerance stack
  • Monte Carlo simulations allows¬†the users to perform advanced statistical Tolerance Analysis on the tolerance stacks whose components/parts may have different levels of process capabilities and on the non-linear tolerance stacks whose standard RSS method cannot provide accurate results.

Inspection Data Management and Assessment


Another major benefit from this system is that First Article Inspection (FAI) data can be stored, managed and assessed much easily. With this system, FAI reports can be prepared with a click of a button. Suppliers can fill in the inspection data quickly. Then the data can be imported and stored back to the central TADM warehouse allowing the engineers to compare and simulate the tolerance stacks with the FAI data and the original design requirements. This helps engineers manage non-conforming requirements, relax tight tolerances on non-critical parts to cut the manufacturing costs, and also reduce design cycle time with the as-built FAI data incorporated into the design process.

iPhone App

Dashboard reporting and high-level summary information is available via TADM app for iPhone users. This complimentary software module lets essential and critical information at the fingertip when a full version of the software is not needed.
