Getting Started with CNC Milling

Computer numerical control, or CNC, is one of the most common and well-known automated processes in manufacturing. CNC machines help companies and individuals make manufacturing processes easier to inspect and control while reducing human errors. They’re used for milling, turning, plasma cutting, electrical discharge machining, water jet cutting, punching, drilling, laser cutting, and more. This […]

The Basics of Electrical Discharge Machining (EDM)

Sometimes when you’re choosing what manufacturing method to use, the requirements for dimensions, materials, and specifications make conventional production processes too expensive. Milling, turning and drilling to machine a block with openings and chamfers that will hold bearings or other components is complex and difficult. Of course, you can cast parts, but the up-front cast […]

The 3 Essential Methods for Gear Machining

Historically, gear fabrication methods fall into three main categories: generation, forming, and form cutting. As new technologies are developed, there may be new gear machining methods added to the list, but the big three are still the most common ways to make a gear: Gear generation methods use cutting tools in the shape of the […]

EDM: Sparks Fly with This Gear Manufacturing Process

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 […]

The Ultimate Guide to Finishing CNC Machined Parts

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, […]

What is ISO 2768? A Guide to Tolerance Standards for CNC Machining

Fabricating a product without deviations from the original design is extremely complicated. Even if you’re able to get an instance comparable to your design intention, it’s nearly impossible to achieve the same exact dimensions in a batch process. That said, you can decide how much a fabricated product can deviate from the original intention in […]
