Advanced CNC - Machining Technician Skill

SHOP NOW What on Earth does 2.5D mean? Today we're going to discuss what the hell 2.5D means, and why it's relevant to CNC machining. We all know that real life objects are 3 dimensional. So, anything that you make on your CNC is 3D. But, like everything else CNC related, there's additional terminology used to describe the different types of parts that can be made on a CNC.   There are 3 different strategies used to create all CNC parts. 2D - This refers to a part where every single feature is cut to the full depth of the material. There is no engraving, there are no pockets, and there are no contoured faces. Anything that a laser cutter makes is...

SHOP NOW What cutters do you need? We've rewritten this email about cutters over and over. It's difficult to find the right balance of giving people the information without sharing so much detail that the big picture is lost. In this latest iteration, we'll skip the technical details and talk about what tools you need for 90% of your projects on a Shapeoko-style machine. How many cutters do you need? Assuming you're working mostly in wood, we're going to say that you need four cutters. 1/4", the Bread and Butter A 1/4" cutter is the perfect blend between capability and strength. It's going to give you good durability, in case you make a mistake, and still be long enough to reach all...

SHOP NOW Going from Idea to Part The best part of owning a CNC machine is that it's like owning a robot that makes whatever you want. (Within reason. We'll get into that later.) The only thing you're limited by is imagination, and when that runs out, there's plenty of inspiration online from other CNC owners. That's fine and good for advanced users but new users are usually trying to get their head around how they go from the picture in their head to a physical project. Central to your design process will be your CAD/CAM software. That's actually two different tasks that may or may not be a single piece ...

SHOP NOW Thanks for signing up! Introduction Thank you for checking out our crash course on CNC machining. This tutorial won't turn you into a machinist, but it will give you enough information to learn more about CNC machines and help you decide if a CNC machine is right for your application. Today, we start by learning the terminology around CNC. Parts of a CNC machine This is the Shapeoko CNC Router from Carbide 3D. This style of machine is known as a "gantry-style CNC". It has a wide, open work area that makes it easy to lay down larger pieces of material. A moving gantry design is optimized far a large work area relative to the overall size of t...
