It’s a given that you need to take your time to perfectly CNC machine a part. But what happens afterwards? Freshly machined parts are covered in machining marks and have edges so sharp that you could use them to carve your overcooked turkey at Thanksgiving dinner — but this is where bead blasting is useful! […]

Historically, gear fabrication methods have been classified into three main categories: generation, forming, and form cutting. As new gear manufacturing technologies are developed, new methods will be added to the list, but for now, those three are still the most common ways for machining a gear: Gear Generation Sunderland Method Rack-type cutters are one of […]

Jacob Schweizer isn’t a household name, but in the engineering world, it should be. It was his desire to build better watches that led to the invention of precision manufacturing equipment now used worldwide. To make watches more portable, he invented the machinery required to build the tiny components that go inside pocket watches and […]

When choosing a metal for your application, there are countless options, and each has pros and cons. Material strength, ductility, toughness, fatigue resistance, hardness, and conductivity are key properties that must be considered when choosing your metal for CNC machining. And depending on the metal, your machining methods and costs can greatly differ due to […]

CAD (Computer Aided Design) and CAM (Computer Aided Manufacturing) are critical software components of modern CNC (Computer Numerical Control) machining. Most modern machine shops make extensive use of CAD and CAM software because the vast majority of manual machines have been replaced by CNC versions. If CAD and CAM terminology has you confused, you aren’t […]

I’ve been through the gauntlet of prototyping, design, and manufacturing a few times. I started out fixing other people’s designs with a hand file, and I’ve also designed involute gears for a low-precision injection mold. Thanks to this breadth of experience, I was able to create a simple cheat sheet for making quick manufacturing decisions […]
