Mechanical Design

I am a Certified Engineering Technologist (CET) , specializing in mechanical design. I work for Optech Incorporated. Optech specializes in laser remote sensing. Most of the things I have worked on have been electronics enclosures and optical sensors and scanners. Much of this has been aircraft mounted.

Calculating Locational Tolerances

As a mechanical designer, I prepare fabrication drawings. I apply a lot of dimensions to holes, and I have to work out tolerances. Finally, I sat down and did the math. If you prepare or check mechanical drawings, this article should be useful for you. This document also is available in Adobe Acrobat format.

Parametric Threads in SolidWorks

You can model a threaded assembly and create fabrication drawings of the parts, and make it so that all the thread specifications update. It does have to be a metric thread. Let me show you how.

Engineering Tips

This is an engineering forum I found on the internet. You can log in and ask technical questions. You can be helpful and answer some of the questions if you know what you are talking about.

Matweb

Here is a very useful database on engineering materials.

Engineering and Technology

This contains all sorts of articles on engineering related topics. I still have an old slide rule lying around somewhere.
