## Using the MEboost Tolerance Calculator

The MEboost tolerance calculator allows you to see the potential rejection rate given a probability distribution for a dimension.  This allows you to estimate rejection rate while balancing the necessary tolerance for functionality. A tolerance range is specified by a range of sigmas (standard deviation) around the nominal dimension, or you can directly specify the …

## Tolerance Analysis Methods

Tolerance analysis is an important part of mechanical design.  It has an impact on cost, performance, and quality which requires a requisite amount of study to ensure tolerances result in a successful design that can be effectively manufactured.  In this article we will look at tolerance analysis methods, and their pros and cons.  We will …

When designing parts for assembly, part symmetry, or lack of symmetry, can be an important factor to consider.  In this article we look at when it’s appropriate to add part symmetry, and when asymmetry is a better option. Symmetrical Parts Designing symmetrical parts, weldments, and sub-assemblies can provide advantages such as reduction of unique parts, …

## Unique Part Number Reduction for the Enterprise

Unique part number reduction across the enterprise can provide numerous benefits.  While it’s desirable to reduce the part count in a given product, what we are focusing on in this article is reducing the unique part numbers in the ERP system across all product lines. For our purposes here, the terms part number or part …

## Evaluating a Manufacturing Decision with a Decision Tree

In this application brief we will look at a manufacturing decision to make a key sub-assembly of a product in-house or to outsource.  If it’s made in-house, we also will look at whether it should be assembled with highly automated process or a more labor intensive process. Therefore, we have three options in our manufacturing …

## Using Monte Carlo Simulation for Purchasing Decisions

Using Monte Carlo simulation for purchasing decisions can allow for overall cost reduction by selecting optimum order quantities.  In this article we will explore how to use simulation to minimize the total cost of a purchased component. When using purchased components, the purchase price is only part of the total cost.  Carrying cost also should …
