4 Ways Excel is Failing Your Tolerance Analysis

4 Ways Excel is Failing Your Tolerance Analysis

Excel is a useful tool for a lot of applications, and can be used in a pinch for stack analysis, but it misses a lot of important features. 

Excel can be used a for a lot of equation based applications. Many companies rely on it for their tolerance analysis; doing 1D stacks and stack-up analysis using Excel macros and Visual Basic code. For basic cases, this works great and can be a fast and effective way to get answers quickly, but as soon as products, models and requirements become more complex, Excel falls flat. 

Integrated CAD tools give more accurate analysis results by incorporating additional influences

This means that your Excel answers might be misleading you, and can cause some embarrassing, and expensive, problems later on. 

In what ways is Excel failing? 

Here are 4 ways Excel is failing your tolerance analysis: 

1. No 3D Influence 

It is rare that all the parts in your product line up into a perfect linear line. Most often, there are parts arranged around your stack-up, and these part's tolerances will influence your linear stack. This 3 dimensional influence can cause more variation than you'd expect, and a 1D stack-up in Excel is not going to account for this.

Even with a linear stack-up, you can have angularity that will cause additional variation, or variation and issues unaccounted for in your Excel stack. These 3 dimensional issues are related to the geometry of the parts, and require a CAD-based approach to properly simulate and validate.  

Not all scenarios can be calculated with an Excel 1D stack-up

Case Study: Structural and Functional Analysis of Drive Train of Major Vehicle System (Star Wars Humor)

Case Study: Structural and Functional Analysis of Drivetrain of Major Transportation System (Humor)

DCS was involved in a previously confidential assignment for a defense OEM to analyze the functional requirements of their primary vehicle's drivetrain. 

DCS has completed a number of projects for aerospace and defense companies, most of which cannot be disclosed. With the declassification of documents in recent years, some of these projects have been approved to be shown.

Back to Basics: How to Quickly Add Points, Moves and Tolerances to Your 3DCS CAD Model

How to Quickly Add Points, Moves and Tolerances to Your 3DCS CAD Model

This Back to Basics article covers a number of ways to quickly add Moves, Tolerances and Points to a 3DCS model

Anyone who has worked with CAD knows that the most time consuming task is preparing the model for analysis. This process is the 'necessary evil' in order to get the results you need to make decisions and validate your GD&T. This is, of course, needed in order to model assembly joints and constraints that mimic the real world. There are, of course, ways of speeding up the process.

CENIT Hosts 3DCS User Meeting in Germany to Showcase Tolerance Analysis

DCS Reseller CENIT Hosts User Meeting in Germany to Showcase the Combination of Tolerance Analysis Software with SPC, CAD and Quality Management

Armin Schöne (Head of Simulation) and his team at CENIT set up a program of interesting lectures on Digital Twins using 3DCS and QDM, 3DCS integrated into Creo, NX and 3DEXPERIENCE.

Nearly 50 visitors from industries like automotive, aviation, engineering and machining took part in the 3DCS User Meeting held in Stuttgart, Germany this week. Hosted by DCS Reseller CENIT, the event showcased new technology in tolerance analysis, as well as the combination of manufacturing software and simulation software to improve production quality and problem solving.
