Topic: A colleague of mine recently forwarded me a paper titled Virtual DOE of an Open-End Wrench. What caught my attention was the use of design of experiment to create a new wrench called the Claw. Does it actually look like a claw? Yes.
For those interested in reading more about the use of Design of Experiment, or maybe you just want to see more of the Claw, I have included a link and the abstract of the paper below for your reading pleasure.

Correlation of test data to FEA simulation can be very useful to understand varied physical phenomena for a given design.
However, lacking a clear goal, it can be hazardous and time consuming. A proposed method to overcome this predicament is to combine FEA simulation with Design of Experiment (DOE) analysis methods – Virtual DOE. One must first come up with a measurable output result, then set up DOE and simulate it using FEA. This method was found to be very time and cost effective in clarifying and analyzing an open-end wrench. Furthermore, it allows flexibility for future investigation and minimizes the time to achieve better results. Virtual DOE simulation may not completely eliminate test; however, it will minimize it. FEA helped Danaher Tool Group to achieve 50% reduction on testing cost and lead to a new innovative product.
The purpose of this paper, Virtual DOE, is to not only demonstrate the power of Virtual DOE versus Physical DOE, but to also explain the process that was used to understand Virtual DOE at Danaher Tool Group and its relationship to test and design improvements.
