Gears can be fabricated using a myriad of different manufacturing methods. As you may expect, the profile of the teeth needs to follow specific dimensions and constraints in order to transmit torque, prevent slippage and excessive undesired contact stresses. Therefore, the fabrication process you select should accomplish the necessary tolerances and properties. This article will […]

M06? G54? S1000? Do those numbers mean anything to you? Knowing the most common commands in your G-code may not be at the top of your priority list, but it can go a long way in helping you understand what your machine is doing. CNC machines are really good at doing exactly what they’re told. […]

Welcome to part II of our three-part series about secondary operations. This article covers finishing options, while the others discuss heat treatments and hardware installation. When discussing CNC machining surface finishing options, you may have heard terms like as-machined, anodizing, powder coating, or media blasting. But before we dig into the details of those processes, […]

It’s not always easy, but don’t make it harder than it needs to be. Moving from 3D printing to injection molding isn’t as simple as just using your computer-aided design (CAD) file with a different piece of equipment. Because 3D printing offers greater design freedom than injection molding, you may need to modify your CAD […]

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 […]

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 […]

“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 […]

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 […]

In the world of plastics, there are a lot of different options for a designer to choose from. There are so many plastic materials, in fact, that the process of selecting the proper 3D printing plastics for prototyping and subsequent manufacturing plastics for production may seem intimidating. This article seeks to clarify the main types of plastic materials […]

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 […]
