Cutting Tools Used in CNC Machining – Choose the Right Tool for the Job

As a mechanical engineer or designer, how much time do you spend thinking about how your parts are going to be machined? Even more specifically, do you know what kinds of tools will be used to make different features or geometries? This article will be your guide to the most common tools used in CNC […]

Introduction to Workholding Options for CNC Machining

Your CNC machining process is only as good as your workholding setup! CNC work holding methods keep your part rigidly in place and reduce the stiffness. You can also refer to work holding as fixturing. A good CNC workholding setup is key for locating the next part to be machined. Fixturing is also important for […]

A Guide to Prototyping Materials for Medical Devices

“Medical device” is a broad umbrella term that covers a huge variety of apparatus and equipment, such as Band-Aids, dental floss, blood pressure cuffs, defibrillators, MRI scanners, and much, much more. It’s probably no surprise that medical device design constitutes a major segment of the field of mechanical engineering, especially in the U.S., which is […]

How to Read Material Data Sheets

To most people, plastics might seem all the same, but to an engineer, plastics come in families, have cousin materials, and have other materials that are as different as cats are from dogs. Of course, our clients expect us to worry about these details, and as nerds, the minute differences between materials, including considerations for […]

PLA vs ABS-like: Getting the Edge on Appearance and Precision

With manufacturing processes evolving quite rapidly in today’s world, it can be difficult to keep up with so many groundbreaking discoveries. In an effort to learn more about the 3D printing world, in particular, I will be showcasing two identical designs composed of two different printing materials: PLA (polylactic acid) and ABS-like (also known as […]

Finding Flexibility: Results of a 3D Printed Strain Wave Gear

One of the most advantageous mechanical gearing systems is the strain wave gear, also known as a harmonic drive. It has high gear reduction ratios (ranging from 30:1 to 320:1), which allow for high speed reduction, no backlash, and high torque, all in a compact and lightweight system. Because of these abilities, the system is […]

How to Accelerate Your Engineering Builds (and Ensure You Get Parts That Fit)

There are very few parts that function on their own—almost every design requires multiple pieces to be joined in some way to create a final product. When was the last time you had something other than a bottle opener that was a single, functional part?  When designing for a multi-part engineering build, there are extra […]

Finite Element Analysis: How to Use Hooke’s Law to Dial in Simple FEAs

Any professional mechanical engineer knows that Finite Element Analysis (FEA) is an essential tool used to analyze stress (deflection, FOS, and more) in a design based on different loading conditions. A huge part of conducting FEA centers around research. When you start the process, you don’t yet know what you don’t know. You need to […]
